The concept of Germany as a distinct region in Central Europe can be traced to Julius Caesar, who referred to the unconquered area east of the Rhine as Germania, thus distinguishing it from Gaul. The victory of the Germanic tribes in the Battle of the Teutoburg Forest (AD 9) prevented annexation by the Roman Empire, although the Roman provinces of Germania Superior and Germania Inferior were established along the Rhine. Following the Fall of the Western Roman Empire, the Franks conquered the other West Germanic tribes. When the Frankish Empire was divided among Charles the Great's heirs in 843, the eastern part became East Francia. In 962, Otto I became the first Holy Roman Emperor of the Holy Roman Empire, the medieval German state.

During the High Middle Ages, the Hanseatic League, dominated by German port cities, established itself along the Baltic and North Seas. The growth of a crusading element within German Christendom led to the State of the Teutonic Order along the Baltic coast in what would later become Prussia. In the Investiture Controversy, the German Emperors resisted Catholic Church authority. In the Late Middle Ages, the regional dukes, princes, and bishops gained power at the expense of the emperors. Martin Luther led the Protestant Reformation within the Catholic Church after 1517, as the northern and eastern states became Protestant, while most of the southern and western states remained Catholic. The Thirty Years' War, a civil war from 1618 to 1648 brought tremendous destruction to the Holy Roman Empire. The estates of the empire attained great autonomy in the Peace of Westphalia, the most important being Austria, Prussia, Bavaria and Saxony. With the Napoleonic Wars, feudalism fell away and the Holy Roman Empire was dissolved in 1806. Napoleon established the Confederation of the Rhine as a German puppet state, but after the French defeat, the German Confederation was established under Austrian presidency. The German revolutions of 1848–1849 failed but the Industrial Revolution modernized the German economy, leading to rapid urban growth and the emergence of the socialist movement. Prussia, with its capital Berlin, grew in power. German universities became world-class centers for science and humanities, while music and art flourished. The unification of Germany was achieved under the leadership of the Chancellor Otto von Bismarck with the formation of the German Empire in 1871. The new Reichstag, an elected parliament, had only a limited role in the imperial government. Germany joined the other powers in colonial expansion in Africa and the Pacific.

By 1900, Germany was the dominant power on the European continent and its rapidly expanding industry had surpassed Britain's while provoking it in a naval arms race. Germany led the Central Powers in World War I, but was defeated, partly occupied, forced to pay war reparations, and stripped of its colonies and significant territory along its borders. The German Revolution of 1918–1919 ended the German Empire with the abdication of Wilhelm II in 1918 and established the Weimar Republic, an ultimately unstable parliamentary democracy. In January 1933, Adolf Hitler, leader of the Nazi Party, used the economic hardships of the Great Depression along with popular resentment over the terms imposed on Germany at the end of World War I to establish a totalitarian regime. This Nazi Germany made racism, especially antisemitism, a central tenet of its policies, and became increasingly aggressive with its territorial demands, threatening war if they were not met. Germany quickly remilitarized, annexed its German-speaking neighbors and invaded Poland, triggering World War II. During the war, the Nazis established a systematic genocide program known as the Holocaust which killed 17 million people, including 6 million Jews (representing 2/3rds of the European Jewish population). By 1944, the German Army was pushed back on all fronts until finally collapsing in May 1945. Under occupation by the Allies, denazification efforts took place, large populations under former German-occupied territories were displaced, German territories were split up by the victorious powers and in the east annexed by Poland and the Soviet Union. Germany spent the entirety of the Cold War era divided into the NATO-aligned West Germany and Warsaw Pact-aligned East Germany. Germans also fled from Communist areas into West Germany, which experienced rapid economic expansion, and became the dominant economy in Western Europe.

In 1989, the Berlin Wall was opened, the Eastern Bloc collapsed, and East and West Germany were reunited in 1990. The Franco-German friendship became the basis for the political integration of Western Europe in the European Union. In 1998–1999, Germany was one of the founding countries of the eurozone. Germany remains one of the economic powerhouses of Europe, contributing about 1/4 of the eurozone's annual gross domestic product. In the early 2010s, Germany played a critical role in trying to resolve the escalating euro crisis, especially concerning Greece and other Southern European nations. In 2015, Germany faced the European migrant crisis as the main receiver of asylum seekers from Syria and other troubled regions. Germany opposed Russia's 2022 invasion of Ukraine and decided to strengthen its armed forces.

Pre-human apes such as Danuvius guggenmosi, who were present in Germany over 11 million years ago, are theorized to be among the earliest apes to walk on two legs prior to other species and genera such as Australopithecus.^[1] The discovery of the Homo heidelbergensis mandible in 1907 affirms archaic human presence in Germany by at least 600,000 years ago,^[2] so stone tools were dated as far back as 1.33 million years ago.^[3] The oldest complete set of hunting weapons ever found anywhere in the world was excavated from a coal mine in Schöningen, Lower Saxony. Between 1994 and 1998, eight 380,000-year-old wooden javelins between 1.82 and 2.25 m (5.97 and 7.38 ft) in length were eventually unearthed.^[4][5] One of the oldest buildings in the world and one of the oldest pieces of art was found in Bilzingsleben.^[6]

In 1856, the fossilized bones of an extinct human species were salvaged from a limestone grotto in the Neander valley near Düsseldorf, North Rhine-Westphalia. The archaic nature of the fossils, now known to be around 40,000 years old, was recognized and the characteristics published in the first-ever paleoanthropologic species description in 1858 by Hermann Schaaffhausen.^[7] The species was named Homo neanderthalensis, Neanderthal man in 1864.

The oldest traces of homo sapiens in Germany were found in the cave Ilsenhöhle [de] in Ranis, where up to 47,500-year-old remains were discovered, among the oldest in Europe.^[8] The remains of Paleolithic early modern human occupation uncovered and documented in several caves in the Swabian Jura include various mammoth ivory sculptures that rank among the oldest uncontested works of art and several flutes, made of bird bone and mammoth ivory that are confirmed to be the oldest musical instruments ever found. The 41,000-year-old Löwenmensch figurine represents the oldest uncontested figurative work of art and the 40,000-year-old Venus of Hohle Fels has been asserted as the oldest uncontested object of human figurative art ever discovered.^{[9][10][11][12]} These artefacts are attributed to the Aurignacian culture.

Between 12,900 and 11,700 years ago, north-central Germany was part of the Ahrensburg culture (named for Ahrensburg).

The first groups of early farmers different from the indigenous hunter-gatherers to migrate into Europe came from a population in western Anatolia at the beginning of the Neolithic period between 10,000 and 8,000 years ago.^[13]

Central Germany was one of the primary areas of the Linear Pottery culture (c. 5500 BC – c. 4500 BC), which was partially contemporary with the Ertebølle culture (c. 5300 BC – c. 3950 BC) of Denmark and northern Germany. The construction of the Central European Neolithic circular enclosures falls in this time period with the best known and oldest being the Goseck circle, constructed c. 4900 BC. Afterwards, Germany was part of the Rössen culture, Michelsberg culture and Funnelbeaker culture (c. 4600 BC – c. 2800 BC). The oldest traces for the use of wheel and wagon ever found are located at a northern German Funnelbeaker culture site and date to around 3400 BC.^[14]

The settlers of the Corded Ware culture (c. 2900 BC – c. 2350 BC), that had spread all over the fertile plains of Central Europe during the Late Neolithic were of Indo-European ancestry. The Indo-Europeans had, via mass-migration, arrived into the heartland of Europe around 4,500 years ago.^[16]

By the late Bronze Age, the Urnfield culture (c. 1300 BC – c. 750 BC) had replaced the Bell Beaker, Unetice and Tumulus cultures in central Europe,^[17] whilst the Nordic Bronze Age had developed in Scandinavia and northern Germany. The name comes from the custom of cremating the dead and placing their ashes in urns, which were then buried in fields. The first usage of the name occurred in publications over grave sites in southern Germany in the late 19th century.^[18][19] Over much of Europe, the Urnfield culture followed the Tumulus culture and was succeeded by the Hallstatt culture.^[20] The Italic peoples, including the Latins, from which the Romans emerged, come from the Urnfield culture of central Europe.^[21][22][23]

The Hallstatt culture, which had developed from the Urnfield culture, was the predominant Western and Central European culture from the 12th to 8th centuries BC and during the early Iron Age (8th to 6th centuries BC). It was followed by the La Tène culture (5th to 1st centuries BC).

The people who had adopted these cultural characteristics in central and southern Germany are regarded as Celts. How and if the Celts are related to the Urnfield culture remains disputed. However, Celtic cultural centres developed in central Europe during the late Bronze Age (c. 1200 BC until 700 BC). Some, like the Heuneburg, the oldest city north of the Alps,^[24] grew to become important cultural centres of the Iron Age in Central Europe, that maintained trade routes to the Mediterranean. In the 5th century BC the Greek historian Herodotus mentioned a Celtic city at the Danube – Pyrene, that historians attribute to the Heuneburg. Beginning around 700 BC (or later), Germanic peoples (Germanic tribes) from southern Scandinavia and northern Germany expanded south and gradually replaced the Celtic peoples in Central Europe.^{[25][26][27][28][29][30]}

The ethnogenesis of the Germanic tribes remains debated. However, for author Averil Cameron "it is obvious that a steady process" occurred during the Nordic Bronze Age, or at the latest during the Pre-Roman Iron Age^[33] (Jastorf culture). From their homes in southern Scandinavia and northern Germany the tribes began expanding south, east and west during the 1st century BC,^[34] and came into contact with the Celtic tribes of Gaul, as well as with Iranic,^[35] Baltic,^[36] and Slavic cultures in Central/Eastern Europe.^[37]

Factual and detailed knowledge about the early history of the Germanic tribes is rare. Researchers have to be content with the recordings of the tribes' affairs with the Romans, linguistic conclusions, archaeological discoveries and the rather new yet auspicious results of archaeogenetic study.^[38] In the mid-1st century BC, Republican Roman statesman Julius Caesar erected the first known bridges across the Rhine during his campaign in Gaul and led a military contingent across and into the territories of the local Germanic tribes. After several days and having made no contact with Germanic troops (who had retreated inland) Caesar returned to the west of the river.^[39] By 60 BC, the Suebi tribe under chieftain Ariovistus, had conquered lands of the Gallic Aedui tribe to the west of the Rhine. Consequent plans to populate the region with Germanic settlers from the east were vehemently opposed by Caesar, who had already launched his ambitious campaign to subjugate all Gaul. Julius Caesar defeated the Suebi forces in 58 BC in the Battle of Vosges and forced Ariovistus to retreat across the Rhine.^[40][41]

Augustus, first Roman emperor, considered conquest beyond the Rhine and the Danube not only regular foreign policy but also necessary to counter Germanic incursions into a still rebellious Gaul. Forts and commercial centers were established along the rivers. Some tribes, such as the Ubii consequently allied with Rome and readily adopted advanced Roman culture. During the 1st century CE Roman legions conducted extended campaigns into Germania magna, the area north of the Upper Danube and east of the Rhine, attempting to subdue the various tribes. Roman ideas of administration, the imposition of taxes and a legal framework were frustrated by the total absence of an infrastructure. Germanicus's campaigns, for example, were almost exclusively characterized by frequent massacres of villagers and indiscriminate pillaging. The tribes, however maintained their elusive identities. A coalition of tribes under the Cherusci chieftain Arminius, who was familiar with Roman tactical doctrines, defeated a large Roman force in the Battle of the Teutoburg Forest. Consequently, Rome resolved to permanently establish the Rhine/Danube border and refrain from further territorial advance into Germania.^[42][43] By AD 100 the frontier along the Rhine and the Danube and the Limes Germanicus was firmly established. Several Germanic tribes lived under Roman rule south and west of the border, as described in Tacitus's Germania. Austria formed the regular provinces of Noricum and Raetia.^[44][45][46] The provinces Germania Inferior (with the capital situated at Colonia Claudia Ara Agrippinensium, modern Cologne) and Germania Superior (with its capital at Mogontiacum, modern Mainz), were formally established in 85 AD, after long campaigns as lasting military control was confined to the lands surrounding the rivers.^[47] Christianity was introduced to Roman controlled western Germania before the Middle Ages, with Christian religious structures such as the Aula Palatina of Trier built during the reign of Constantine I (r. 306–337).^[48]

Rome's Third Century Crisis coincided with the emergence of a number of large West Germanic tribes: the Alamanni, Franks, Bavarii, Chatti, Saxons, Frisii, Sicambri, and Thuringii. By the 3rd century the Germanic speaking peoples began to migrate beyond the limes and the Danube frontier.^[49] Several large tribes – the Visigoths, Ostrogoths, Vandals, Burgundians, Lombards, Saxons and Franks – migrated and played their part in the decline of the Roman Empire and the transformation of the old Western Roman Empire.^[50] By the end of the 4th century the Huns invaded eastern and central Europe, establishing the Hunnic Empire. The event triggered the Migration Period.^[51] Hunnic hegemony over a vast territory in central and eastern Europe lasted until the death of Attila's son Dengizich in 469.^[52] Another pivotal moment in the Migration Period was the Crossing of the Rhine in December of 406 by a large group of tribes including Vandals, Alans and Suebi who settled permanently within the crumbling Western Roman Empire.^[53]

Stem duchies (German: Stammesherzogtümer) in Germany refer to the traditional territory of the various Germanic tribes. The concept of such duchies survived especially in the areas which by the 9th century would constitute East Francia,^[54] which included the Duchy of Bavaria, the Duchy of Swabia, the Duchy of Saxony, the Duchy of Franconia and the Duchy of Thuringia,^[55] unlike further west the County of Burgundy or Lorraine in Middle Francia.^{[56] [57]}

The Salian emperors (reigned 1027–1125) retained the stem duchies as the major divisions of Germany, but they became increasingly obsolete during the early high-medieval period under the Hohenstaufen, and Frederick Barbarossa finally abolished them in 1180 in favour of more numerous territorial duchies.

Successive kings of Germany founded a series of border counties or marches in the east and the north. These included Lusatia, the North March (which would become Brandenburg and the heart of the future Prussia), and the Billung March. In the south, the marches included Carniola, Styria, and the March of Austria that would become Austria.

The Western Roman Empire fell in 476 with the deposition of Romulus Augustus by the Germanic foederati leader Odoacer, who became the first King of Italy.^[58] Afterwards, the Franks, like other post-Roman Western Europeans, emerged as a tribal confederacy in the Middle Rhine-Weser region, among the territory soon to be called Austrasia (the "eastern land"), the northeastern portion of the future Kingdom of the Merovingian Franks. As a whole, Austrasia comprised parts of present-day France, Germany, Belgium, Luxembourg and the Netherlands. Unlike the Alamanni to their south in Swabia, they absorbed large swaths of former Roman territory as they spread west into Gaul, beginning in 250. Clovis I of the Merovingian dynasty conquered northern Gaul in 486 and in the Battle of Tolbiac in 496 the Alemanni tribe in Swabia, which eventually became the Duchy of Swabia.

By 500, Clovis had united all the Frankish tribes, ruled all of Gaul^[59] and was proclaimed King of the Franks between 509 and 511.^[60] Clovis, unlike most Germanic rulers of the time, was baptized directly into Roman Catholicism instead of Arianism. His successors would cooperate closely with papal missionaries, among them Saint Boniface. After the death of Clovis in 511, his four sons partitioned his kingdom including Austrasia. Authority over Austrasia passed back and forth from autonomy to royal subjugation, as successive Merovingian kings alternately united and subdivided the Frankish lands.^[61]

During the 5th and 6th centuries the Merovingian kings conquered the Thuringii (531 to 532), the Kingdom of the Burgundians and the principality of Metz and defeated the Danes, the Saxons and the Visigoths.^[62] King Chlothar I (558 to 561) ruled the greater part of what is now Germany and undertook military expeditions into Saxony, while the South-east of what is modern Germany remained under the influence of the Ostrogoths. Saxons controlled the area from the northern sea board to the Harz Mountains and the Eichsfeld in the south.^[63]

The Merovingians placed the various regions of their Frankish Empire under the control of semi-autonomous dukes – either Franks or local rulers,^[64] and followed imperial Roman strategic traditions of social and political integration of the newly conquered territories.^[65][66] While allowed to preserve their own legal systems,^[67] the conquered Germanic tribes were pressured to abandon the Arian Christian faith.^[68]

In 718 Charles Martel waged war against the Saxons in support of the Neustrians. In 743 his son Carloman in his role as Mayor of the Palace renewed the war against the Saxons, who had allied with and aided the duke Odilo of Bavaria.^[69] The Catholic Franks, who by 750 controlled a vast territory in Gaul, north-western Germany, Swabia, Burgundy and western Switzerland, that included the alpine passes allied with the Curia in Rome against the Lombards, who posed a permanent threat to the Holy See.^[59] Pressed by Liutprand, King of the Lombards, a Papal envoy for help had already been sent to the de facto ruler Charles Martel after his victory in 732 over the forces of the Umayyad Caliphate at the Battle of Tours, however a lasting and mutually beneficial alliance would only materialize after Charles' death under his successor Duke of the Franks, Pepin the Short.^[70]

In 751 Pippin III, Mayor of the Palace under the Merovingian king, himself assumed the title of king and was anointed by the Church. Pope Stephen II bestowed him the hereditary title of Patricius Romanorum as protector of Rome and St. Peter^[71] in response to the Donation of Pepin, that guaranteed the sovereignty of the Papal States. Charles the Great (who ruled the Franks from 774 to 814) launched a decades-long military campaign against the Franks' heathen rivals, the Saxons and the Avars. The campaigns and insurrections of the Saxon Wars lasted from 772 to 804. The Franks eventually overwhelmed the Saxons and Avars, forcibly converted the people to Christianity, and annexed their lands to the Carolingian Empire.

After the death of Frankish king Pepin the Short in 768, his oldest son "Charlemagne" ("Charles the Great") consolidated his power over and expanded the Kingdom. Charlemagne ended 200 years of Royal Lombard rule with the Siege of Pavia, and in 774 he installed himself as King of the Lombards. Loyal Frankish nobles replaced the old Lombard aristocracy following a rebellion in 776.^[72] The next 30 years of his reign were spent ruthlessly strengthening his power in Francia and on the conquest of the Slavs and Pannonian Avars in the east and all tribes, such as the Saxons and the Bavarians.^[73][74] On Christmas Day, 800 AD, Charlemagne was crowned Imperator Romanorum (Emperor of the Romans) in Rome by Pope Leo III.^[74]

Fighting among Charlemagne's three grandsons over the continuation of the custom of partible inheritance or the introduction of primogeniture caused the Carolingian empire to be partitioned into three parts by the Treaty of Verdun of 843.^[75] Louis the German received the Eastern portion of the kingdom, East Francia, all lands east of the Rhine river and to the north of Italy. This encompassed the territories of the German stem duchies – Franks, Saxons, Swabians, and Bavarians – that were united in a federation under the first non-Frankish king Henry the Fowler, who ruled from 919 to 936.^[76] The royal court permanently moved in between a series of strongholds, called Kaiserpfalzen, that developed into economic and cultural centers. Aachen Palace played a central role, as the local Palatine Chapel served as the official site for all royal coronation ceremonies during the entire Medieval period until 1531.^[74][77]

In 936, Otto I was crowned German king at Aachen, in 961 King of Italy in Pavia and crowned emperor by Pope John XII in Rome in 962. The tradition of the German King as protector of the Kingdom of Italy and the Latin Church resulted in the term Holy Roman Empire in the 12th century. The name, that was to identify with Germany continued to be used officially, with the extension added: Nationis Germanicæ (of the German nation) after the last imperial coronation in Rome in 1452 until its dissolution in 1806.^[76] Otto strengthened the royal authority by re-asserting the old Carolingian rights over ecclesiastical appointments.^[78] Otto wrested from the nobles the powers of appointment of the bishops and abbots, who controlled large land holdings. Additionally, Otto revived the old Carolingian program of appointing missionaries in the border lands. Otto continued to support celibacy for the higher clergy, so ecclesiastical appointments never became hereditary. By granting lands to the abbots and bishops he appointed, Otto actually turned these bishops into "princes of the Empire" (Reichsfürsten).^[79] In this way, Otto was able to establish a national church. Outside threats to the kingdom were contained with the decisive defeat of the Hungarian Magyars at the Battle of Lechfeld in 955. The Slavs between the Elbe and the Oder rivers were also subjugated. Otto marched on Rome and drove John XII from the papal throne and for years controlled the election of the pope, setting a firm precedent for imperial control of the papacy for years to come.^[80][81]

Otto I was followed on the throne by his son Otto II (955–983), emperor 973–983, Otto II’s wife Theophanu (955–991), regent 983–991, his own wife Adelaide of Italy (931–999), regent 991–995, and his grandson Otto III (980–1002), emperor 996–1002. Otto III died childless and was succeeded by his second cousin Henry II, who likewise died childless as the last emperor of the Ottonian dynasty.

Henry II was succeeded by Conrad II, a great-great-grandson of Otto I and the first emperor of the Salian dynasty. During the reign of Conrad II's son, Henry III (1039 to 1056), the empire supported the Cluniac reforms of the Church, the Peace of God, prohibition of simony (the purchase of clerical offices), and required celibacy of priests. Imperial authority over the Pope reached its peak. However, Rome reacted with the creation of the College of Cardinals and Pope Gregory VII's series of clerical reforms. Pope Gregory insisted in his Dictatus Papae on absolute papal authority over appointments to ecclesiastical offices. The subsequent conflict in which emperor Henry IV was compelled to submit to the Pope at Canossa in 1077, after having been excommunicated came to be known as the Investiture Controversy. In 1122, a temporary reconciliation was reached between Henry V and the Pope with the Concordat of Worms. With the conclusion of the dispute the Roman church and the papacy regained supreme control over all religious affairs.^[83][84] Consequently, the imperial Ottonian church system (Reichskirche) declined. It also ended the royal/imperial tradition of appointing selected powerful clerical leaders to counter the Imperial secular princes.^[85]

Between 1095 and 1291 the various campaigns of the crusades to the Holy Land took place. Knightly religious orders were established, including the Knights Templar, the Knights of St John (Knights Hospitaller), and the Teutonic Order.^[86][87]

The term sacrum imperium (Holy Empire) was first used officially by Friedrich I in 1157,^[88] but the words Sacrum Romanum Imperium, Holy Roman Empire, were only combined in July 1180 and would never consistently appear on official documents from 1254 onwards.^[89]

The Hanseatic League was a commercial and defensive alliance of the merchant guilds of towns and cities in northern and central Europe that dominated marine trade in the Baltic Sea, the North Sea and along the connected navigable rivers during the Late Middle Ages ( 12th to 15th centuries ). Each of the affiliated cities retained the legal system of its sovereign and, with the exception of the Free imperial cities, had only a limited degree of political autonomy.^[90] Beginning with an agreement of the cities of Lübeck and Hamburg, guilds cooperated in order to strengthen and combine their economic assets, like securing trading routes and tax privileges, to control prices and better protect and market their local commodities. Important centers of commerce within the empire, such as Cologne on the Rhine river and Bremen on the North Sea joined the union, which resulted in greater diplomatic esteem.^[91] Recognized by the various regional princes for the great economic potential, favorable charters for, often exclusive, commercial operations were granted.^[92] During its zenith the alliance maintained trading posts and kontors in virtually all cities between London and Edinburgh in the west to Novgorod in the east and Bergen in Norway. By the late 14th century the powerful league enforced its interests with military means, if necessary. This culminated in a war with the sovereign Kingdom of Denmark from 1361 to 1370. Principal city of the Hanseatic League remained Lübeck, where in 1356 the first general diet was held and its official structure was announced. The league declined after 1450 due to a number of factors, such as the 15th-century crisis, the territorial lords' shifting policies towards greater commercial control, the silver crisis and marginalization in the wider Eurasian trade network, among others.^[93][94]

The Ostsiedlung (lit. Eastern settlement) is the term for a process of largely uncoordinated immigration and chartering of settlement structures by ethnic Germans into territories, already inhabited by Slavs and Balts east of the Saale and Elbe rivers, such as modern Poland and Silesia and to the south into Bohemia, modern Hungary and Romania during the High Middle Ages from the 11th to the 14th century.^[95][96] The primary purpose of the early imperial military campaigns into the lands to the east during the 10th and 11th century, was to punish and subjugate the local heathen tribes. Conquered territories were mostly lost after the troops had retreated, but eventually were incorporated into the empire as marches, fortified borderlands with garrisoned troops in strongholds and castles, who were to ensure military control and enforce the exaction of tributes. Contemporary sources do not support the idea of policies or plans for the organized settlement of civilians.^[97]

Emperor Lothair II re-established feudal sovereignty over Poland, Denmark and Bohemia from 1135 and appointed margraves to turn the borderlands into hereditary fiefs and install a civilian administration. There is no discernible chronology of the immigration process as it took place in many individual efforts and stages, often even encouraged by the Slavic regional lords. However, the new communities were subjected to German law and customs. Total numbers of settlers were generally rather low and, depending on who held a numerical majority, populations usually assimilated into each other. In many regions only enclaves would persist, like Hermannstadt, founded by the Transylvanian Saxons in the medieval Hungarian Kingdom (today in Romania) who were called on by Geza II to repopulate the area as part of the Ostsiedlung, having arrived there and founding the city in 1147 [Saxons called these parts of Transylvania "Altland" to distinguish them from later immigrant Saxon settlements established in about 1220 by the Teutonic Order].^[98][99]

In 1230, the Catholic monastic order of the Teutonic Knights launched the Prussian Crusade. The campaign, that was supported by the forces of Polish duke Konrad I of Masovia, initially intended to Christianize the Baltic Old Prussians, succeeded primarily in the conquest of large territories. The order, emboldened by imperial approval, quickly resolved to establish an independent state, without the consent of duke Konrad. Recognizing only papal authority and based on a solid economy, the order steadily expanded the Teutonic state during the following 150 years, engaging in several land disputes with its neighbors. Permanent conflicts with the Kingdom of Poland, the Grand Duchy of Lithuania, and the Novgorod Republic, eventually led to military defeat and containment by the mid-15th century. The last Grand Master Albert of Brandenburg converted to Lutheranism in 1525 and turned the remaining lands of the order into the secular Duchy of Prussia.^[100][101]

Henry V, great-grandson of Conrad II, who had overthrown his father Henry IV became Holy Roman Emperor in 1111. Hoping to gain greater control over the church inside the Empire, Henry V appointed Adalbert of Saarbrücken as the powerful archbishop of Mainz in the same year. Adalbert began to assert the powers of the Church against secular authorities, that is, the Emperor. This precipitated the "Crisis of 1111" as yet another chapter of the long-term Investiture Controversy.^[102] In 1137, the prince-electors turned back to the Hohenstaufen family for a candidate, Conrad III. Conrad tried to divest his rival Henry the Proud of his two duchies—Bavaria and Saxony—that led to war in southern Germany as the empire was divided into two powerful factions. The faction of the Welfs or Guelphs (in Italian) supported the House of Welf of Henry the Proud, which was the ruling dynasty in the Duchy of Bavaria. The rival faction of the Waiblings or Ghibellines (in Italian) pledged allegiance to the Swabian House of Hohenstaufen. During this early period, the Welfs generally maintained ecclesiastical independence under the papacy and political particularism (the focus on ducal interests against the central imperial authority). The Waiblings, on the other hand, championed strict control of the church and a strong central imperial government.^[103]

During the reign of the Hohenstaufen emperor Frederick I (Barbarossa), an accommodation was reached in 1156 between the two factions. The Duchy of Bavaria was returned to Henry the Proud's son Henry the Lion, duke of Saxony, who represented the Guelph party. However, the Margraviate of Austria was separated from Bavaria and turned into the independent Duchy of Austria by virtue of the Privilegium Minus in 1156.^[104]

Having become wealthy through trade, the confident cities of Northern Italy, supported by the Pope, increasingly opposed Barbarossa's claim of feudal rule (Honor Imperii) over Italy. The cities united in the Lombard League and finally defeated Barbarossa in the Battle of Legnano in 1176. The following year a reconciliation was reached between the emperor and Pope Alexander III in the Treaty of Venice.^[105] The 1183 Peace of Constance eventually settled that the Italian cities remained loyal to the empire but were granted local jurisdiction and full regal rights in their territories.^[106]

In 1180, Henry the Lion was outlawed, Saxony was divided, and Bavaria was given to Otto of Wittelsbach, who founded the Wittelsbach dynasty, which was to rule Bavaria until 1918.

From 1184 to 1186, the empire under Frederick I Barbarossa reached its cultural peak with the Diet of Pentecost held at Mainz and the marriage of his son Henry in Milan to the Norman princess Constance of Sicily.^[107] The power of the feudal lords was undermined by the appointment of ministerials (unfree servants of the Emperor) as officials. Chivalry and the court life flowered, as expressed in the scholastic philosophy of Albertus Magnus and the literature of Wolfram von Eschenbach.^[108]

Between 1212 and 1250, Frederick II established a modern, professionally administered state from his base in Sicily. He resumed the conquest of Italy, leading to further conflict with the Papacy. In the Empire, extensive sovereign powers were granted to ecclesiastical and secular princes, leading to the rise of independent territorial states. The struggle with the Pope sapped the Empire's strength, as Frederick II was excommunicated three times. After his death, the Hohenstaufen dynasty fell, followed by an interregnum during which there was no Emperor (1250–1273). This interregnum came to an end with the election of a small Swabian count, Rudolf of Habsburg, as emperor.^[109][110]

The failure of negotiations between Emperor Louis IV and the papacy led to the 1338 Declaration at Rhense by six princes of the Imperial Estate to the effect that election by all or the majority of the electors automatically conferred the royal title and rule over the empire, without papal confirmation. As result, the monarch was no longer subject to papal approbation and became increasingly dependent on the favour of the electors. Between 1346 and 1378 Emperor Charles IV of Luxembourg, king of Bohemia, sought to restore imperial authority. The 1356 decree of the Golden Bull stipulated that all future emperors were to be chosen by a college of only seven – four secular and three clerical – electors. The secular electors were the King of Bohemia, the Count Palatine of the Rhine, the Duke of Saxony, and the Margrave of Brandenburg, the clerical electors were the Archbishops of Mainz, Trier, and Cologne.^[111]

Between 1347 and 1351 Germany and almost the entire European continent were consumed by the most severe outbreak of the Black Death pandemic. Estimated to have caused the abrupt death of 30 to 60% of Europe's population, it led to widespread social and economic disruption and deep religious disaffection and fanaticism. Minority groups, and Jews in particular were blamed, singled out and attacked. As a consequence, many Jews fled and resettled in Eastern Europe.^[112][113]

Total population estimates of the German territories range around 5 to 6 million by the end of Henry III's reign in 1056 and about 7 to 8 million after Friedrich Barbarossa's rule in 1190.^[114][115] The vast majority were farmers, typically in a state of serfdom under feudal lords and monasteries.^[103] Towns gradually emerged and in the 12th century many new cities were founded along the trading routes and near imperial strongholds and castles. The towns were subjected to the municipal legal system. Cities such as Cologne, that had acquired the status of Imperial Free Cities, were no longer answerable to the local landlords or bishops, but immediate subjects of the Emperor and enjoyed greater commercial and legal liberties.^[116] The towns were ruled by a council of the – usually mercantile – elite, the patricians. Craftsmen formed guilds, governed by strict rules, which sought to obtain control of the towns; a few were open to women. Society had diversified, but was divided into sharply demarcated classes of the clergy, physicians, merchants, various guilds of artisans, unskilled day labourers and peasants. Full citizenship was not available to paupers. Political tensions arose from issues of taxation, public spending, regulation of business, and market supervision, as well as the limits of corporate autonomy.^[117]

Cologne's central location on the Rhine river placed it at the intersection of the major trade routes between east and west and was the basis of Cologne's growth.^[118] The economic structures of medieval and early modern Cologne were characterized by the city's status as a major harbor and transport hub upon the Rhine. It was the seat of an archbishop, under whose patronage the vast Cologne Cathedral was built since 1240. The cathedral houses sacred Christian relics and it has since become a well known pilgrimage destination. By 1288 the city had secured its independence from the archbishop (who relocated to Bonn), and was ruled by its burghers.^[119]

Benedictine abbess Hildegard von Bingen wrote several influential theological, botanical, and medicinal texts, as well as letters, liturgical songs, poems, and arguably the oldest surviving morality play, Ordo Virtutum, while supervising brilliant miniature Illuminations. About 100 years later, Walther von der Vogelweide became the most celebrated of the Minnesänger, who were Middle High German lyric poets.

Around 1439, Johannes Gutenberg of Mainz, used movable type printing and issued the Gutenberg Bible. He was the global inventor of the printing press, thereby starting the Printing Revolution. Cheap printed books and pamphlets played central roles for the spread of the Reformation and the Scientific Revolution.

Around the transition from the 15th to the 16th century, Albrecht Dürer from Nuremberg established his reputation across Europe as painter, printmaker, mathematician, engraver, and theorist when he was still in his twenties and secured his reputation as one of the most important figures of the Northern Renaissance.

See List of states in the Holy Roman Empire for subdivisions and the political structure

The early-modern European society gradually developed after the disasters of the 14th century as religious obedience and political loyalties declined in the wake of the Great Plague, the schism of the Church and prolonged dynastic wars. The rise of the cities and the emergence of the new burgher class eroded the societal, legal and economic order of feudalism.^[127]

The commercial enterprises of the mercantile elites in the quickly developing cities in South Germany (such as Augsburg and Nuremberg), with the most prominent families being the Gossembrots, Fuggers (the wealthiest family in Europe during the fifteenth and sixteenth centuries^[130]), Welsers, Hochstetters, Imholts, generated unprecedented financial means. As financiers to both the leading ecclesiastical and secular rulers, these families fundamentally influenced the political affairs in the empire during the fifteenth and sixteenth century.^{[131][132][133][134]} The increasingly money based economy also provoked social discontent among knights and peasants and predatory "robber knights" became common.^[135]

From 1438 the Habsburg dynasty, who had acquired control in the south-eastern empire over the Duchy of Austria, Bohemia and Hungary after the death of King Louis II in 1526, managed to permanently occupy the position of the Holy Roman Emperor until 1806 (with the exception of the years between 1742 and 1745).

Some Europe-wide revolutions were born in the Empire: the combination of the first modern postal system established by Maximilian (with the management under the Taxis family) with the printing system invented by Gutenberg produced a communication revolution^{[136][137][138]} – the Empire's decentralized nature made censorship difficult and this combined with the new communication system to facilitate free expression, thus elevating cultural life. The system also helped the authorities to disseminate orders and policies, boosted the Empire's coherence in general, and helped reformers like Luther to broadcast their views and communicate with each other effectively, thus contributing to the religious Reformation.^{[139][140][141]}

Maximilian's military reforms, especially his development of the Landsknechte, caused a military revolution that broke the back of the knight class^[142][143] and spread all over Europe shortly after his death.^[144][145]

During his reign from 1493 to 1519, Maximilian I, in a combined effort with the Estates (who sometimes acted as opponents and sometimes as cooperators to him), his officials and his humanists, reformed the empire. A dual system of Supreme Courts (the Reichskammergericht and the Reichshofrat) was established (with the Reichshofrat playing a more efficient role during the Early Modern period),^[150] together with the formalized Reception of Roman Law;^{[151][152][153][154]} the Imperial Diet (Reichstag) became the all-important political forum and the supreme legal and constitutional institution, which would act as a guarantee for the preservation of the Empire in the long run;^[155][156] a Permanent Land Piece (Ewiger Landfriede) was declared in 1495 with regional leagues and unions providing the supporting structure, together with the creation of the Reichskreise (Imperial Circles, which would serve the purpose of organize imperial armies, collect taxes and enforce orders of the imperial institutions);^{[157][158][159]} the Imperial and Court Chanceries were combined to become the decisive government institution;^[160][161] the Landsknechte that Maximilian created became a form of imperial army;^[162] a national political culture began to emerge;^[163][164] and the German language began to attain an unified form.^[165][166] The political structure remained incomplete and piecemeal though, mainly due to the failure of the Common Penny (an imperial tax) that the Estates resisted.^[150][a] Through many compromises between emperor and estates though, a flexible, future-oriented problem-solving mechanism for the Empire was formed, together with a monarchy through which the emperor shared power with the Estates.^[168][b] Whether the Reform also equated to a (successful or unsuccessful) nation building process remains a debate.^[170]

The addition Nationis Germanicæ (of German Nation) to the emperor's title appeared first in the 15th century: in a 1486 law decreed by Frederick III and in 1512 in reference to the Imperial Diet in Cologne by Maximilian I. In 1525, the Heilbronn reform plan – the most advanced document of the German Peasants' War (Deutscher Bauernkrieg) – referred to the Reich as von Teutscher Nation (of German nation). During the fifteen century, the term "German nation" had witness a rise in use due to the growth of a "community of interests". The Estates also increasingly distinguished between their German Reich and the wider, "universal" Reich.^[171]

In order to manage their ever growing expenses, the Renaissance Popes of the 15th and early 16th century promoted the excessive sale of indulgences and offices and titles of the Roman Curia.

In 1517, the monk Martin Luther published a pamphlet with 95 Theses that he posted in the town square of Wittenberg and handed copies of to feudal lords. Whether he nailed them to a church door at Wittenberg remains unclear. The list detailed 95 assertions, he argued, represented corrupt practice of the Christian faith and misconduct within the Catholic Church. Although perhaps not Luther's chief concern, he received popular support for his condemnation of the sale of indulgences and clerical offices, the pope's and higher clergy's abuse of power and his doubts of the very idea of the institution of the Church and the papacy.^[172]

The Protestant Reformation was the first successful challenge to the Catholic Church and began in 1521 as Luther was outlawed at the Diet of Worms after his refusal to repent. The ideas of the reformation spread rapidly, as the new technology of the modern printing press ensured cheap mass copies and distribution of the theses and helped by the Emperor Charles V's wars with France and the Turks.^[172] Hiding in the Wartburg Castle, Luther translated the Bible into German, thereby greatly contributing to the establishment of the modern German language. This is highlighted by the fact that Luther spoke only a local dialect of minor importance during that time. After the publication of his Bible, his dialect suppressed others and constitutes to a great extent what is now modern German. With the protestation of the Lutheran princes at the Imperial Diet of Speyer in 1529 and the acceptance and adoption of the Lutheran Augsburg Confession by the Lutheran princes beginning in 1530, the separate Lutheran church was established.^[173]

The German Peasants' War, which began in the southwest in Alsace and Swabia and spread further east into Franconia, Thuringia and Austria, was a series of economic and religious revolts of the rural lower classes, encouraged by the rhetoric of various radical religious reformers and Anabaptists against the ruling feudal lords. Although occasionally assisted by war-experienced noblemen like Götz von Berlichingen and Florian Geyer (in Franconia) and the theologian Thomas Müntzer (in Thuringia), the peasant forces lacked military structure, skill, logistics and equipment and as many as 100,000 insurgents were eventually defeated and massacred by the territorial princes.^[174]

The Catholic Counter-Reformation, initiated in 1545 at the Council of Trent was spearheaded by the scholarly religious Jesuit order, that was founded just five years prior by several clerics around Ignatius of Loyola. Its intent was to challenge and contain the Protestant Reformation via apologetic and polemical writings and decrees, ecclesiastical reconfiguration, wars and imperial political maneuverings. In 1547, emperor Charles V defeated the Schmalkaldic League, a military alliance of Protestant rulers.^[175] The 1555 Peace of Augsburg decreed the recognition of the Lutheran Faith and religious division of the empire. It also stipulated the ruler's right to determine the official confession in his principality (Cuius regio, eius religio). The Counter-Reformation eventually failed to reintegrate the central and northern German Lutheran states. In 1608/1609 the Protestant Union and the Catholic League were formed.

The 1618 to 1648 Thirty Years' War, that took place almost exclusively in the Holy Roman Empire has its origins, which remain widely debated, in the unsolved and recurring conflicts of the Catholic and Protestant factions. The Catholic emperor Ferdinand II attempted to achieve the religious and political unity of the empire, while the opposing Protestant Union forces were determined to defend their religious rights. The religious motive served as the universal justification for the various territorial and foreign princes, who over the course of several stages joined either of the two warring parties in order to gain land and power.^[176][177]

The conflict was sparked by the revolt of the Protestant nobility of Bohemia against emperor Matthias' succession policies. After imperial triumph at the Battle of White Mountain and a short-lived peace, the war grew to become a political European conflict by the intervention of King Christian IV of Denmark from 1625 to 1630, Gustavus Adolphus of Sweden from 1630 to 1648 and France under Cardinal Richelieu from 1635 to 1648. The conflict increasingly evolved into a struggle between the French House of Bourbon and the House of Habsburg for predominance in Europe, for which the central German territories of the empire served as the battleground.^[178]

The war ranks among the most catastrophic in history as three decades of constant warfare and destruction had left the land devastated. Marauding armies incessantly pillaged the countryside, seized and levied heavy taxes on cities and indiscriminately plundered the food stocks of the peasantry. There were also the countless bands of murderous outlaws, sick, homeless, disrupted people and invalid soldiery. Overall social and economic disruption caused a dramatic decline in population as a result of pandemic murder and random rape and killings, endemic infectious diseases, crop failures, famine, declining birth rates, wanton burglary, witch-hunts and the emigration of terrified people. Estimates vary between a 38% drop from 16 million people in 1618 to 10 million by 1650 and a mere 20% drop from 20 million to 16 million. The Altmark and Württemberg regions were especially hard hit, where it took generations to fully recover.^[176][179]

The war was the last major religious struggle in mainland Europe and ended in 1648 with the Peace of Westphalia. It resulted in increased autonomy for the constituent states of the Holy Roman Empire, limiting the power of the emperor. Most of Alsace was ceded to France, Western Pomerania and Bremen-Verden were given to Sweden as Imperial fiefs, and the Netherlands officially left the Empire.^[180]

The population of Germany reached about twenty million people by the mid-16th century, the great majority of whom were peasant farmers.^[182]

The Protestant Reformation was a triumph for literacy and the new printing press.^{[183][c][185][186]} Luther's translation of the Bible into High German (the New Testament was published in 1522; the Old Testament was published in parts and completed in 1534) was a decisive impulse for the increase of literacy in early modern Germany,^[181] and stimulated printing and distribution of religious books and pamphlets. From 1517 onward religious pamphlets flooded Germany and much of Europe. The Reformation instigated a media revolution as by 1530 over 10,000 individual works are published with a total of ten million copies. Luther strengthened his attacks on Rome by depicting a "good" against "bad" church. It soon became clear that print could be used for propaganda in the Reformation for particular agendas. Reform writers used pre-Reformation styles, clichés, and stereotypes and changed items as needed for their own purposes.^[187] Especially effective were Luther's Small Catechism, for use of parents teaching their children, and Larger Catechism, for pastors.^[188] Using the German vernacular they expressed the Apostles' Creed in simpler, more personal, Trinitarian language. Illustrations in the newly translated Bible and in many tracts popularized Luther's ideas. Lucas Cranach the Elder, the painter patronized by the electors of Wittenberg, was a close friend of Luther, and illustrated Luther's theology for a popular audience. He dramatized Luther's views on the relationship between the Old and New Testaments, while remaining mindful of Luther's careful distinctions about proper and improper uses of visual imagery.^[189]

Luther's translation of the Bible into High German was also decisive for the German language and its evolution from Early New High German to Modern Standard German.^[181] The publication of Luther's Bible was a decisive moment in the spread of literacy in early modern Germany,^[181] and promoted the development of non-local forms of language and exposed all speakers to forms of German from outside their own area.^[190]

Notable late fifteenth to early eighteenth-century polymaths include: Johannes Trithemius, one of the founder of modern cryptography, founder of steganography, as well as bibliography and literary studies as branches of knowledge;^{[191][192][193]} Conrad Celtes, the first and foremost German cartographic writer and "the greatest lyric genius and certainly the greatest organizer and popularizer of German Humanism";^{[194][195][196][197]} Athanasius Kircher, described by Fletcher as "a founder figure of various disciplines—of geology (certainly vulcanology), musicology (as a surveyor of musical forms), museum curatorship, Coptology, to name a few—and might be claimed today as the first theorist of gravity and a long-term originator of the moving pictures (with his magic lantern shows). Through his many enthusiasms, moreover, he was the conduit of others' pursuits in the rapidly widening horizon of knowledge that marks the later Renaissance.";^[198] and Gottfried Wilhelm Leibniz, one of the greatest, if not the greatest "Universal genius", of all times.^[199][200]

Cartography developed strongly, with the center being Nuremberg, at the beginning of the sixteenth century. Martin Waldseemüller and Matthias Ringmann's Universalis Cosmographia and the 1513 edition of Geography marked the climax of a cartography revolution.^[201][202] The emperor himself dabbled in cartography.^[203]

In 1515, Johannes Stabius (court astronomer under Maximilian I), Albrecht Dürer and the astronomer Konrad Heinfogel produced the first planispheres of both southern and northerns hemispheres, also the first printed celestial maps. These maps prompted the revival of interest in the field of uranometry throughout Europe.^{[204][205][206][207]}

Astronomer Johannes Kepler from Weil der Stadt was one of the pioneering minds of empirical and rational research. Through rigorous application of the principles of the Scientific method he construed his laws of planetary motion. His ideas influenced contemporary Italian scientist Galileo Galilei and provided fundamental mechanical principles for Isaac Newton's theory of universal gravitation.^[208]

German Colonies in the Americas existed because the Free Imperial Cities of Augsburg and Nuremberg got colonial rights in the Province of Venezuela or North of South America in return for debts owed by the Holy Roman Empire Charles V, who was also King of Spain. In 1528, Charles V issued a charter by which the Welser family possessed the rights to explore, rule and colonize the area, also with the motivation of searching for the legendary golden city of El Dorado. Their principal colony was Klein-Venedig. A never realized colonial project was Hanauish-Indies intended by Friedrich Casimir, Count of Hanau-Lichtenberg as a fief of the Dutch West India Company. The project failed due to a lack of funds and the outbreak of the Franco-Dutch War in 1672.

Frederick William, ruler of Brandenburg-Prussia since 1640 and later called the Great Elector, acquired East Pomerania via the Peace of Westphalia in 1648. He reorganized his loose and scattered territories and managed to throw off the vassalage of Prussia under the Kingdom of Poland during the Second Northern War.^[212] In order to address the demographic problem of Prussia's largely rural population of about three million, he attracted the immigration and settlement of French Huguenots in urban areas. Many became craftsmen and entrepreneurs.^[213] King Frederick William I, known as the Soldier King, who reigned from 1713 to 1740, established the structures for the highly centralized Prussian state and raised a professional army, that was to play a central role.^[214] He also successfully operated a command economy that some historians consider mercantilist.^[215][216]

The total population of Germany (in its 1914 territorial extent) grew from 16 million in 1700 to 17 million in 1750 and reached 24 million in 1800. The 18th-century economy noticeably profited from widespread practical application of the Scientific method as greater yields and a more reliable agricultural production and the introduction of hygienic standards positively affected the birth rate – death rate balance.^[217]

Louis XIV of France waged a series of successful wars in order to extend the French territory. He occupied Lorraine (1670) and annexed the remainder of Alsace (1678–1681) that included the free imperial city of Straßburg. At the start of the Nine Years' War, he also invaded the Electorate of the Palatinate (1688–1697).^[218] Louis established a number of courts whose sole function was to reinterpret historic decrees and treaties, the Treaties of Nijmegen (1678) and the Peace of Westphalia (1648) in particular in favor of his policies of conquest. He considered the conclusions of these courts, the Chambres de réunion as sufficient justification for his boundless annexations. Louis' forces operated inside the Holy Roman Empire largely unopposed, because all available imperial contingents fought in Austria in the Great Turkish War. The Grand Alliance of 1689 took up arms against France and countered any further military advances of Louis. The conflict ended in 1697 as both parties agreed to peace talks after either side had realized, that a total victory was financially unattainable. The Treaty of Ryswick provided for the return of the Lorraine and Luxembourg to the empire and the abandoning of French claims to the Palatinate.^[219]

After the last-minute relief of Vienna from a siege and the imminent seizure by a Turkish force in 1683, the combined troops of the Holy League, that had been founded the following year, embarked on the military containment of the Ottoman Empire and reconquered Hungary in 1687.^[220] The Papal States, the Holy Roman Empire, the Polish–Lithuanian Commonwealth, the Republic of Venice and since 1686 Russia had joined the league under the leadership of Pope Innocent XI. Prince Eugene of Savoy, who served under emperor Leopold I, took supreme command in 1697 and decisively defeated the Ottomans in a series of spectacular battles and manoeuvres. The 1699 Treaty of Karlowitz marked the end of the Great Turkish War and Prince Eugene continued his service for the Habsburg monarchy as president of the War Council. He effectively ended Turkish rule over most of the territorial states in the Balkans during the Austro-Turkish War of 1716–1718. The Treaty of Passarowitz left Austria to freely establish royal domains in Serbia and the Banat and maintain hegemony in Southeast Europe, on which the future Austrian Empire was based.^[221][222]

Frederick II "the Great" is best known for his military genius and unique utilisation of the highly organized army to make Prussia one of the great powers in Europe as well as escaping from almost certain national disaster at the last minute. He was also an artist, author and philosopher, who conceived and promoted the concept of enlightened absolutism.^[223][224]

Austrian empress Maria Theresa succeeded in bringing about a favorable conclusion for her in the 1740 to 1748 war for recognition of her succession to the throne. However, Silesia was permanently lost to Prussia as a consequence of the Silesian Wars and the Seven Years' War. The 1763 Treaty of Hubertusburg ruled that Austria and Saxony had to relinquish all claims to Silesia. Prussia, that had nearly doubled its territory was eventually recognized as a great European power with the consequence that the politics of the following century were fundamentally influenced by German dualism, the rivalry of Austria and Prussia for supremacy in Central Europe.^[225]

The concept of enlightened absolutism, although rejected by the nobility and citizenry, was advocated in Prussia and Austria and implemented since 1763. Prussian king Frederick II defended the idea in an essay and argued that the benevolent monarch simply is the first servant of the state, who effects his absolute political power for the benefit of the population as a whole. A number of legal reforms (e.g. the abolition of torture and the emancipation of the rural population and the Jews), the reorganization of the Prussian Academy of Sciences, the introduction of compulsory education for boys and girls and promotion of religious tolerance, among others, caused rapid social and economic development.^[226]

During 1772 to 1795 Prussia instigated the partitions of Poland by occupying the western territories of the former Polish–Lithuanian Commonwealth. Austria and Russia resolved to acquire the remaining lands with the effect that Poland ceased to exist as a sovereign state until 1918.^[227]

The smaller German states were overshadowed by Prussia and Austria. Bavaria had a rural economy. Saxony was in economically good shape, although numerous wars had taken their toll. During the time when Prussia rose rapidly within Germany, Saxony was distracted by foreign affairs. The House of Wettin concentrated on acquiring and then holding on to the Polish throne which was ultimately unsuccessful.^{[228][clarification needed]}

Many of the smaller states of Germany were run by bishops, who in reality were from powerful noble families and showed scant interest in religion. While none of the later ecclesial rulers reached the outstanding reputation of Mainz' Johann Philipp von Schönborn or Münster's Christoph Bernhard von Galen, some of them promoted Enlightenment like the benevolent and progressive Franz Ludwig von Erthal in Würzburg and Bamberg.^[229]

In Hesse-Kassel, the Landgrave Frederick II, ruled from 1760 to 1785 as an enlightened despot, and raised money by renting soldiers (called "Hessians") to Great Britain to help fight the American Revolutionary War. He combined Enlightenment ideas with Christian values, cameralist plans for central control of the economy, and a militaristic approach toward diplomacy.^[230]

Hanover did not have to support a lavish court—its rulers were also kings of England and resided in London. George III, elector (ruler) from 1760 to 1820, never once visited Hanover. The local nobility who ran the country opened the University of Göttingen in 1737; it soon became a world-class intellectual center. Baden sported perhaps the best government of the smaller states. Karl Friedrich ruled for 73 years and was an enthusiast for the Enlightenment; he abolished serfdom in 1783.^[231]

The smaller states failed to form coalitions with each other, and were eventually overwhelmed by Prussia who swallowed up many of them between 1807 and 1871.^[232]

Prussia underwent major social change between the mid-17th and mid-18th centuries as the nobility declined as the traditional aristocracy struggled to compete with the rising merchant class,^[233] which developed into a new Bourgeoisie middle class,^{[234][235][236]} while the emancipation of the serfs granted the rural peasantry land purchasing rights and freedom of movement,^[237] and a series of agrarian reforms in northwestern Germany abolished feudal obligations and divided up feudal land, giving rise to wealthier peasants and paved the way for a more efficient rural economy.^[238]

During the mid-18th century, the recognition and application of Enlightenment cultural, intellectual and spiritual ideals and standards, led to a flourishing of art, music, philosophy, science and literature. The philosopher Christian Wolff was a pioneering author in a vast number of fields of Enlightenment rationality, and established German as the prevailing language of philosophical reasoning, scholarly instruction and research.^[239]

In 1685, Margrave Frederick William of Prussia issued the Edict of Potsdam within a week after French king Louis XIV's Edict of Fontainebleau, that decreed the abolishment of the 1598 concession to free religious practice for Protestants. Frederick William offered his co-religionists, who are oppressed and assailed for the sake of the Holy Gospel and its pure doctrine...a secure and free refuge in all Our Lands.^[240] Around 20,000 Huguenot refugees arrived in an immediate wave and settled in the cities, 40% in Berlin, the ducal residence alone. The French Lyceum in Berlin was established in 1689 and the French language had by the end of the 17th century replaced Latin to be spoken universally in international diplomacy. The nobility and the educated middle-class of Prussia and the various German states increasingly used the French language in public conversation in combination with universal cultivated manners. Like no other German state, Prussia had access to and the skill set for the application of pan-European Enlightenment ideas to develop more rational political and administrative institutions.^[241] The princes of Saxony carried out a comprehensive series of fundamental fiscal, administrative, judicial, educational, cultural and general economic reforms. The reforms were aided by the country's strong urban structure and influential commercial groups, who modernized pre-1789 Saxony along the lines of classic Enlightenment principles.^[242]

Johann Gottfried von Herder broke new ground in philosophy and poetry, as a leader of the Sturm und Drang movement of proto-Romanticism. Weimar Classicism ("Weimarer Klassik") was a cultural and literary movement based in Weimar that sought to establish a new humanism by synthesizing Romantic, classical, and Enlightenment ideas. The movement, from 1772 until 1805, involved Herder as well as polymath Johann Wolfgang von Goethe and Friedrich Schiller, a poet and historian. Herder argued that every folk had its own particular identity, which was expressed in its language and culture. This legitimized the promotion of German language and culture and helped shape the development of German nationalism. Schiller's plays expressed the restless spirit of his generation, depicting the hero's struggle against social pressures and the force of destiny.^[243]

German music, sponsored by the upper classes, came of age under composers Johann Sebastian Bach, Joseph Haydn, and Wolfgang Amadeus Mozart.^[244]

Königsberg philosopher Immanuel Kant tried to reconcile rationalism and religious belief, individual freedom, and political authority. Kant's work contained basic tensions that would continue to shape German thought – and indeed all of European philosophy – well into the 20th century.^[245][246] The ideas of the Enlightenment and their implementation received general approval and recognition as principal cause for widespread cultural progress.^[247]

German reaction to the French Revolution was mixed at first. German intellectuals celebrated the outbreak, hoping to see the triumph of Reason and The Enlightenment. The royal courts in Vienna and Berlin denounced the overthrow of the king and the threatened spread of notions of liberty, equality, and fraternity. By 1793, the execution of the French king and the onset of the Terror disillusioned the Bildungsbürgertum (educated middle classes). Reformers said the solution was to have faith in the ability of Germans to reform their laws and institutions in peaceful fashion.^[248]

Europe was racked by two decades of war revolving around France's efforts to spread its revolutionary ideals, and the opposition of reactionary royalty. War broke out in 1792 as Austria and Prussia invaded France, but were defeated at the Battle of Valmy (1792). The German lands saw armies marching back and forth, bringing devastation (albeit on a far lower scale than the Thirty Years' War, almost two centuries before), but also bringing new ideas of liberty and civil rights for the people. Prussia and Austria ended their failed wars with France but (with Russia) partitioned Poland among themselves in 1793 and 1795.

France took control of the Rhineland, imposed French-style reforms, abolished feudalism, established constitutions, promoted freedom of religion, emancipated Jews, opened the bureaucracy to ordinary citizens of talent, and forced the nobility to share power with the rising middle class. Napoleon created the Kingdom of Westphalia as a model state.^[249] These reforms proved largely permanent and modernized the western parts of Germany. When the French tried to impose the French language, German opposition grew in intensity. A Second Coalition of Britain, Russia, and Austria then attacked France but failed. Napoleon established direct or indirect control over most of western Europe, including the German states apart from Prussia and Austria. The old Holy Roman Empire was little more than a farce; Napoleon simply abolished it in 1806 while forming new countries under his control. In Germany Napoleon set up the "Confederation of the Rhine", comprising most of the German states except Prussia and Austria.^[250]

Under Frederick William II's weak rule (1786–1797) Prussia had undergone a serious economic, political and military decline. His successor king Frederick William III tried to remain neutral during the War of the Third Coalition and French emperor Napoleon's dissolution of the Holy Roman Empire and reorganisation of the German principalities. Induced by the queen and a pro-war party Frederick William joined the Fourth Coalition in October 1806. Napoleon easily defeated the Prussian army at the Battle of Jena and occupied Berlin. Prussia lost its recently acquired territories in western Germany, its army was reduced to 42,000 men, no trade with Britain was allowed and Berlin had to pay Paris high reparations and fund the French army of occupation. Saxony changed sides to support Napoleon and joined the Confederation of the Rhine. Ruler Frederick Augustus I was rewarded with the title of king and given a part of Poland taken from Prussia, which became known as the Duchy of Warsaw.^[251]

After Napoleon's military fiasco in Russia in 1812, Prussia allied with Russia in the Sixth Coalition. A series of battles followed and Austria joined the alliance. Napoleon was decisively defeated in the Battle of Leipzig in late 1813. The German states of the Confederation of the Rhine defected to the Coalition against Napoleon, who rejected any peace terms. Coalition forces invaded France in early 1814, Paris fell and in April Napoleon surrendered. Prussia as one of the winners at the Congress of Vienna, gained extensive territory.^[217]

In 1815, continental Europe was in a state of overall turbulence and exhaustion, as a consequence of the French Revolutionary and Napoleonic Wars. The liberal spirit of the Enlightenment and Revolutionary era diverged toward Romanticism.^[252] The victorious members of the Coalition had negotiated a new peaceful balance of powers in Vienna and agreed to maintain a stable German heartland that keeps French imperialism at bay. However, the idea of reforming the defunct Holy Roman Empire was discarded. Napoleon's reorganization of the German states was continued and the remaining princes were allowed to keep their titles. In 1813, in return for guarantees from the Allies that the sovereignty and integrity of the Southern German states (Baden, Württemberg, and Bavaria) would be preserved, they broke with France.^[253]

During the 1815 Congress of Vienna the 39 former states of the Confederation of the Rhine joined the German Confederation, a loose agreement for mutual defense. Attempts of economic integration and customs coordination were frustrated by repressive anti-national policies. Great Britain approved of the union, convinced that a stable, peaceful entity in central Europe could discourage aggressive moves by France or Russia. Most historians, however, concluded, that the Confederation was weak and ineffective and an obstacle to German nationalism. The union was undermined by the creation of the Zollverein in 1834, the 1848 revolutions, the rivalry between Prussia and Austria and was finally dissolved in the wake of the Austro-Prussian War of 1866,^[254] to be replaced by the North German Confederation during the same year.^[254]

Increasingly after 1815, a centralized Prussian government based in Berlin took over the powers of the nobles, which in terms of control over the peasantry had been almost absolute. To help the nobility avoid indebtedness, Berlin set up a credit institution to provide capital loans in 1809, and extended the loan network to peasants in 1849. When the German Empire was established in 1871, the Junker nobility controlled the army and the navy, the bureaucracy, and the royal court; they generally set governmental policies.^[255]

Between 1815 and 1865 the population of the German Confederation (excluding Austria) grew around 60% from 21 million to 34 million.^[256] Simultaneously the Demographic Transition took place as the high birth rates and high death rates of the pre-industrial country shifted to low birth and death rates of the fast-growing industrialized urban economic and agricultural system. Increased agricultural productivity secured a steady food supply, as famines and epidemics declined. This allowed people to marry earlier, and have more children. The high birthrate was offset by a very high rate of infant mortality and after 1840, large-scale emigration to the United States. Emigration totaled at 480,000 in the 1840s, 1,200,000 in the 1850s, and at 780,000 in the 1860s. The upper and middle classes first practiced birth control, soon to be universally adopted.^[257]

In 1800, Germany's social structure was poorly suited to entrepreneurship or economic development. Domination by France during the French Revolution (1790s to 1815), however, produced important institutional reforms, that included the abolition of feudal restrictions on the sale of large landed estates, the reduction of the power of the guilds in the cities, and the introduction of a new, more efficient commercial law. The idea, that these reforms were beneficial for Industrialization has been contested.^[258]

In the early 19th century the Industrial Revolution was in full swing in Britain, France, and Belgium. The various small federal states in Germany developed only slowly and independently as competition was strong. Early investments for the railway network during the 1830s came almost exclusively from private hands. Without a central regulatory agency the construction projects were quickly realized. Actual industrialization only took off after 1850 in the wake of the railroad construction.^[259] The textile industry grew rapidly, profiting from the elimination of tariff barriers by the Zollverein.^[260][261] During the second half of the 19th century the German industry grew exponentially and by 1900, Germany was an industrial world leader along with Britain and the United States.^[262]</ref>

In 1800, the population was predominantly rural, as only 10% lived in communities of 5,000 or more people, and only 2% lived in cities of more than 100,000 people. After 1815, the urban population grew rapidly, due to the influx of young people from the rural areas. Berlin grew from 172,000 in 1800, to 826,000 inhabitants in 1870, Hamburg from 130,000 to 290,000, Munich from 40,000 to 269,000 and Dresden from 60,000 to 177,000.^[263]

The takeoff stage of economic development came with the railroad revolution in the 1840s, which opened up new markets for local products, created a pool of middle managers, increased the demand for engineers, architects and skilled machinists and stimulated investments in coal and iron. Political disunity of three dozen states and a pervasive conservatism made it difficult to build railways in the 1830s. However, by the 1840s, trunk lines did link the major cities; each German state was responsible for the lines within its own borders. Economist Friedrich List summed up the advantages to be derived from the development of the railway system in 1841:

• 1. As a means of national defence, it facilitates the concentration, distribution and direction of the army.
• 2. It is a means to the improvement of the culture of the nation. It brings talent, knowledge and skill of every kind readily to market.
• 3. It secures the community against dearth and famine, and against excessive fluctuation in the prices of the necessaries of life.
• 4. It promotes the spirit of the nation, as it has a tendency to destroy the Philistine spirit arising from isolation and provincial prejudice and vanity. It binds nations by ligaments, and promotes an interchange of food and of commodities, thus making it feel to be a unit. The iron rails become a nerve system, which, on the one hand, strengthens public opinion, and, on the other hand, strengthens the power of the state for police and governmental purposes.^[264]

Lacking a technological base at first, engineering and hardware was imported from Britain. In many cities, the new railway shops were the centres of technological awareness and training, so that by 1850, Germany was self-sufficient in meeting the demands of railroad construction, and the railways were a major impetus for the growth of the new steel industry. Observers found that even as late as 1890, their engineering was inferior to Britain. However, German unification in 1870 stimulated consolidation, nationalisation into state-owned companies, and further rapid growth. Unlike the situation in France, the goal was the support of industrialisation. Eventually numerous lines criss-crossed the Ruhr area and other industrial centers and provided good connections to the major ports of Hamburg and Bremen. By 1880, 9,400 locomotives pulled 43,000 passengers and 30,000 tons of freight a day.^[259]

While there existed no national newspaper the many states issued a great variety of printed media, although they rarely exceeded regional significance. In a typical town existed one or two outlets, urban centers, such as Berlin and Leipzig had dozens. The audience was limited to a few per cent of male adults, chiefly from the aristocratic and upper middle class. Liberal publishers outnumbered conservative ones by a wide margin. Foreign governments bribed editors to guarantee a favorable image.^[265] Censorship was strict, and the imperial government issued the political news that was supposed to be published. After 1871, strict press laws were enforced by Bismarck to contain the Socialists and hostile editors. Editors focused on political commentary, culture, the arts, high culture and the popular serialized novels. Magazines were politically more influential and attracted intellectual authors.^[266]

19th-century artists and intellectuals were greatly inspired by the ideas of the French Revolution and the great poets and writers Johann Wolfgang von Goethe, Gotthold Ephraim Lessing and Friedrich Schiller. The Sturm und Drang romantic movement was embraced and emotion was given free expression in reaction to the perceived rationalism of the Enlightenment. Philosophical principles and methods were revolutionized by Immanuel Kant's paradigm shift. Ludwig van Beethoven was the most influential composer of the period from classical to Romantic music. His use of tonal architecture in such a way as to allow significant expansion of musical forms and structures was immediately recognized as bringing a new dimension to music. His later piano music and string quartets, especially, showed the way to a completely unexplored musical universe, and influenced Franz Schubert and Robert Schumann. In opera, a new Romantic atmosphere combining supernatural terror and melodramatic plot in a folkloric context was first successfully achieved by Carl Maria von Weber and perfected by Richard Wagner in his Ring Cycle. The Brothers Grimm collected folk stories into the popular Grimm's Fairy Tales and are ranked among the founding fathers of German studies, who initiated the work on the Deutsches Wörterbuch ("The German Dictionary"), the most comprehensive work on the German language.^[267]

University professors developed international reputations, especially in the humanities led by history and philology, which brought a new historical perspective to the study of political history, theology, philosophy, language, and literature. With Georg Wilhelm Friedrich Hegel, Friedrich Wilhelm Joseph Schelling, Arthur Schopenhauer, Friedrich Nietzsche, Max Weber, Karl Marx and Friedrich Engels in philosophy, Friedrich Schleiermacher in theology and Leopold von Ranke in history became famous. The University of Berlin, founded in 1810, became the world's leading university. Von Ranke, for example, professionalized history and set the world standard for historiography. By the 1830s mathematics, physics, chemistry, and biology had emerged with world class science, led by Alexander von Humboldt in natural science and Carl Friedrich Gauss in mathematics. Young intellectuals often turned to politics, but their support for the failed revolution of 1848 forced many into exile.^[217]

Two main developments reshaped religion in Germany. Across the land, there was a movement to unite the larger Lutheran and the smaller Reformed Protestant churches. The churches themselves brought this about in Baden, Nassau, and Bavaria. However, in Prussia King Frederick William III was determined to handle unification entirely on his own terms, without consultation. His goal was to unify the Protestant churches, and to impose a single standardized liturgy, organization and even architecture. The long-term goal was to have fully centralized royal control of all the Protestant churches. In a series of proclamations over several decades the Church of the Prussian Union was formed, bringing together the more numerous Lutherans, and the less numerous Reformed Protestants. The government of Prussia now had full control over church affairs, with the king himself recognized as the leading bishop. Opposition to unification came from the "Old Lutherans" in Silesia who clung tightly to the theological and liturgical forms they had followed since the days of Luther. The government attempted to crack down on them, so they went underground. Tens of thousands migrated, to South Australia, and especially to the United States, where they formed the Missouri Synod, which is still in operation as a conservative denomination. Finally in 1845 a new king Frederick William IV offered a general amnesty and allowed the Old Lutherans to form a separate church association with only nominal government control.^{[268][269][270]}

From the religious point of view of the typical Catholic or Protestant, major changes were underway in terms of a much more personalized religiosity that focused on the individual more than the church or the ceremony. The rationalism of the late 19th century faded away, and there was a new emphasis on the psychology and feeling of the individual, especially in terms of contemplating sinfulness, redemption, and the mysteries and the revelations of Christianity. Pietistic revivals were common among Protestants. Among, Catholics there was a sharp increase in popular pilgrimages. In 1844 alone, half a million pilgrims made a pilgrimage to the city of Trier in the Rhineland to view the Seamless robe of Jesus, said to be the robe that Jesus wore on the way to his crucifixion. Catholic bishops in Germany had historically been largely independent of Rome, but now the Vatican exerted increasing control, a new "ultramontanism" of Catholics highly loyal to Rome.^[271] A sharp controversy broke out in 1837–1838 in the largely Catholic Rhineland over the religious education of children of mixed marriages, where the mother was Catholic and the father Protestant. The government passed laws to require that these children always be raised as Protestants, contrary to Napoleonic law that had previously prevailed and allowed the parents to make the decision. It put the Catholic Archbishop under house arrest. In 1840, the new King Frederick William IV sought reconciliation and ended the controversy by agreeing to most of the Catholic demands. However Catholic memories remained deep and led to a sense that Catholics always needed to stick together in the face of an untrustworthy government.^[272]

After the fall of Napoleon, Europe's statesmen convened in Vienna in 1815 for the reorganisation of European affairs, under the leadership of the Austrian Prince Metternich. The political principles agreed upon at this Congress of Vienna included the restoration, legitimacy and solidarity of rulers for the repression of revolutionary and nationalist ideas.

The German Confederation (German: Deutscher Bund) was founded, a loose union of 39 states (35 ruling princes and 4 free cities) under Austrian leadership, with a Federal Diet (German: Bundestag) meeting in Frankfurt am Main. It was a loose coalition that failed to satisfy most nationalists. The member states largely went their own way, and Austria had its own interests.

In 1819, a student radical assassinated the reactionary playwright August von Kotzebue, who had scoffed at liberal student organisations. In one of the few major actions of the German Confederation, Prince Metternich called a conference that issued the repressive Carlsbad Decrees, designed to suppress liberal agitation against the conservative governments of the German states.^[273] The Decrees terminated the fast-fading nationalist fraternities (German: Burschenschaften), removed liberal university professors, and expanded the censorship of the press. The decrees began the "persecution of the demagogues", which was directed against individuals who were accused of spreading revolutionary and nationalist ideas. Among the persecuted were the poet Ernst Moritz Arndt, the publisher Johann Joseph Görres and the "Father of Gymnastics" Ludwig Jahn.^[274]

In 1834, the Zollverein was established, a customs union between Prussia and most other German states, but excluding Austria. As industrialisation developed, the need for a unified German state with a uniform currency, legal system, and government became more and more obvious.

Growing discontent with the political and social order imposed by the Congress of Vienna led to the outbreak, in 1848, of the March Revolution in the German states. In May the German National Assembly (the Frankfurt Parliament) met in Frankfurt to draw up a national German constitution.

But the 1848 revolution turned out to be unsuccessful: King Frederick William IV of Prussia refused the imperial crown, the Frankfurt parliament was dissolved, the ruling princes repressed the risings by military force, and the German Confederation was re-established by 1850. Many leaders went into exile, including a number who went to the United States and became a political force there.^[275]

The 1850s were a period of extreme political reaction. Dissent was vigorously suppressed, and many Germans emigrated to America following the collapse of the 1848 uprisings. Frederick William IV became extremely depressed and melancholic during this period, and was surrounded by men who advocated clericalism and absolute divine monarchy. The Prussian people once again lost interest in politics. Prussia not only expanded its territory but began to industrialize rapidly, while maintaining a strong agricultural base.

In 1857, the Prussian king Frederick William IV suffered a stroke and his brother William served as regent until 1861 when he became King William I. Although conservative, William was very pragmatic. His most significant accomplishment was the naming of Otto von Bismarck as Prussian minister president in 1862. The cooperation of Bismarck, Defense Minister Albrecht von Roon, and Field Marshal Helmut von Moltke set the stage for the military victories over Denmark, Austria, and France, that led to the unification of Germany.^[276][277]

In 1863–1864, disputes between Prussia and Denmark over Schleswig escalated, which was not part of the German Confederation, and which Danish nationalists wanted to incorporate into the Danish kingdom. The conflict led to the Second War of Schleswig in 1864. Prussia, joined by Austria, easily defeated Denmark and occupied Jutland. The Danes were forced to cede both the Duchy of Schleswig and the Duchy of Holstein to Austria and Prussia. The subsequent management of the two duchies led to tensions between Austria and Prussia. Austria wanted the duchies to become an independent entity within the German Confederation, while Prussia intended to annex them. The disagreement served as a pretext for the Seven Weeks War between Austria and Prussia, that broke out in June 1866. In July, the two armies clashed at Sadowa-Königgrätz (Bohemia) in an enormous battle involving half a million men. Prussian superior logistics and the modern breech-loading needle guns superiority over the slow muzzle-loading rifles of the Austrians, proved to be elementary for Prussia's victory. The battle had also decided the struggle for hegemony in Germany and Bismarck was deliberately lenient with defeated Austria, that was to play only a subordinate role in future German affairs.^[278][279]

After the Seven Weeks War, the German Confederation was dissolved and the North German Federation (German Norddeutscher Bund) was established under the leadership of Prussia. Austria was excluded and its immense influence over Germany finally came to an end. The North German Federation was a transitional organisation that existed from 1867 to 1871, between the dissolution of the German Confederation and the founding of the German Empire.^[280]

Chancellor Otto von Bismarck determined the political course of the German Empire until 1890. He fostered alliances in Europe to contain France on the one hand and aspired to consolidate Germany's influence in Europe on the other. His principal domestic policies focused on the suppression of socialism and the reduction of the strong influence of the Roman Catholic Church on its adherents. He issued a series of anti-socialist laws in accord with a set of social laws, that included universal health care, pension plans and other social security programs. His Kulturkampf policies were vehemently resisted by Catholics, who organized political opposition in the Center Party (Zentrum). German industrial and economic power had grown to match Britain by 1900.

In 1888, the young and ambitious Kaiser Wilhelm II became emperor. He rejected advice from experienced politicians and ordered Bismarck's resignation in 1890. He opposed Bismarck's careful and delicate foreign policy and was determined to pursue colonialist policies, as Britain and France had been doing for centuries. The Kaiser promoted the active colonization of Africa and Asia for the lands that were not already colonies of other European powers. The Kaiser took a mostly unilateral approach in Europe only allied with the Austro-Hungarian Empire, and embarked on a dangerous naval arms race with Britain. His aggressive and erroneous policies greatly contributed to the situation in which the assassination of the Austrian-Hungarian crown prince would spark off World War I.

Bismarck was the dominant personality not just in Germany but in all of Europe and indeed the entire diplomatic world 1870–1890. Historians continue to debate his goals. Lothar Gall and Ernst Engelberg consider Bismarck was a future-oriented modernizer. In sharp contrast, Jonathan Steinberg decided he was basically a traditional Prussian whose highest priorities were to reinforce the monarchy, the Army, and the social and economic dominance of his own Junker class, thereby being responsible for a tragic history after his removal in 1890.^[281]

In 1868, the Spanish queen Isabella II was deposed in the Glorious Revolution, leaving the country's throne vacant. When Prussia suggested the Hohenzollern candidate, Prince Leopold as successor, France vehemently objected. The matter evolved into a diplomatic scandal and in July 1870, France resolved to end it in a full-scale war. The conflict was quickly decided as Prussia, joined by forces of a pan-German alliance never gave up the tactical initiative. A series of victories in north-eastern France followed and another French army group was simultaneously encircled at Metz. A few weeks later, the French army contingent under Emperor Napoleon III's personal command was finally forced to capitulate in the fortress of Sedan.^[282][283] Napoleon was taken prisoner and a provisional government hastily proclaimed in Paris. The new government resolved to fight on and tried to reorganize the remaining armies while the Germans settled down to besiege Paris. The starving city surrendered in January 1871 and Jules Favre signed the surrender at Versailles. France was forced to pay indemnities of 5 billion francs and cede Alsace-Lorraine to Germany. This conclusion left the French national psyche deeply humiliated and further aggravated the French–German enmity.

During the Siege of Paris, the German princes assembled in the Hall of Mirrors of the Palace of Versailles on 18 January 1871 and announced the establishment of the German Empire and proclaimed the Prussian King Wilhelm I as German Emperor. The act unified all ethnic German states with the exception of Austria in the Little German solution of a federal economic, political and administrative unit. Bismarck, was appointed to serve as Chancellor.

The new empire was a federal union of 25 states that varied considerably in size, demography, constitution, economy, culture, religion and socio-political development. However, even Prussia itself, which accounted for two-thirds of the territory as well as of the population, had emerged from the empire's periphery as a newcomer. It also faced colossal cultural and economic internal divisions. The Prussian provinces of Westphalia and the Rhineland for example had been under French control during the previous decades. The local people, who had benefited from the liberal, civil reforms, that were derived from the ideas of the French Revolution, had only little in common with predominantly rural communities in authoritarian and disjointed Junker estates of Pommerania.^[284] The inhabitants of the smaller territorial lands, especially in central and southern Germany greatly rejected the Prussianized concept of the nation and preferred to associate such terms with their individual home state. The Hanseatic port cities of Hamburg, Bremen and Lübeck ranked among the most ferocious opponents of the so-called contract with Prussia. As advocates of free trade, they objected to Prussian ideas of economic integration and refused to sign the renewed Zollverein (Custom Union) treaties until 1888.^[285] The Hanseatic merchants' overseas economic success corresponded with their globalist mindset. The citizen of Hamburg, whom Bismark characterized as extremely irritating and the German ambassador in London as the worst Germans we have, were particularly appalled by Prussian militarism and its unopposed growing influence.^{[286][unreliable source?]}

The Prusso-German authorities were aware of necessary integration concepts as the results and the 52% voter turnout of the first imperial elections had clearly demonstrated. Historians increasingly argue, that the nation-state was forged through empire.^[287] National identity was expressed in bombastic imperial stone iconography and was to be achieved as an imperial people, with an emperor as head of state and it was to develop imperial ambitions – domestic, European and global.^[288][287]

Bismarck's domestic policies as Chancellor of Germany were based on his effort to universally adopt the idea of the Protestant Prussian state and achieve the clear separation of church and state in all imperial principalities. In the Kulturkampf (lit.: culture struggle) from 1871 to 1878, he tried to minimize the influence of the Roman Catholic Church and its political arm, the Catholic Centre Party, via secularization of all education and introduction of civil marriage, but without success. The Kulturkampf antagonised many Protestants as well as Catholics and was eventually abandoned. The millions of non-German imperial subjects, like the Polish, Danish and French minorities, were left with no choice but to endure discrimination or accept^[289][290] the policies of Germanisation.

The new Empire provided attractive top level career opportunities for the national nobility in the various branches of the consular and civil services and the army. As a consequence the aristocratic near total control of the civil sector guaranteed a dominant voice in the decision making in the universities and the churches. The 1914 German diplomatic corps consisted of 8 princes, 29 counts, 20 barons, 54 representants of the lower nobility and a mere 11 commoners. These commoners were indiscriminately recruited from elite industrialist and banking families. The consular corps employed numerous commoners, that however, occupied positions of little to no executive power.^[291] The Prussian tradition to reserve the highest military ranks for young aristocrats was adopted and the new constitution put all military affairs under the direct control of the Emperor and beyond control of the Reichstag.^[292] With its large corps of reserve officers across Germany, the military strengthened its role as "The estate which upheld the nation", and historian Hans-Ulrich Wehler added: "it became an almost separate, self-perpetuating caste".^[293]

Power increasingly was centralized among the 7000 aristocrats, who resided in the national capital of Berlin and neighboring Potsdam. Berlin's rapidly increasing rich middle-class copied the aristocracy and tried to marry into it. A peerage could permanently boost a rich industrial family into the upper reaches of the establishment.^[294] However, the process tended to work in the other direction as the nobility became industrialists. For example, 221 of the 243 mines in Silesia were owned by nobles or by the King of Prussia himself.^[295]

The middle class in the cities grew exponentially, although it never acquired the powerful parliamentary representation and legislative rights as in France, Britain or the United States. The Association of German Women's Organizations or BDF was established in 1894 to encompass the proliferating women's organizations that had emerged since the 1860s. From the beginning the BDF was a bourgeois organization, its members working toward equality with men in such areas as education, financial opportunities, and political life. Working-class women were not welcome and were organized by the Socialists.^[296]

The rise of the Socialist Workers' Party (later known as the Social Democratic Party of Germany, SPD), aimed to peacefully establish a socialist order through the transformation of the existing political and social conditions. From 1878, Bismarck tried to oppose the growing social democratic movement by outlawing the party's organisation, its assemblies and most of its newspapers. Nonetheless, the Social Democrats grew stronger and Bismarck initiated his social welfare program in 1883 in order to appease the working class.^[297]

Bismarck built on a tradition of welfare programs in Prussia and Saxony that began as early as the 1840s. In the 1880s he introduced old age pensions, accident insurance, medical care, and unemployment insurance that formed the basis of the modern European welfare state. His paternalistic programs won the support of German industry because its goals were to win the support of the working classes for the Empire and reduce the outflow of immigrants to America, where wages were higher but welfare did not exist.^[298][299] Bismarck further won the support of both industry and skilled workers by his high tariff policies, which protected profits and wages from American competition, although they alienated the liberal intellectuals who wanted free trade.^[300][301]

Bismarck would not tolerate any power outside Germany—as in Rome—having a say in domestic affairs. He launched the Kulturkampf ("culture war") against the power of the pope and the Catholic Church in 1873, but only in the state of Prussia. This gained strong support from German liberals, who saw the Catholic Church as the bastion of reaction and their greatest enemy. The Catholic element, in turn, saw in the National-Liberals the worst enemy and formed the Center Party.^[302]

Catholics, although nearly a third of the national population, were seldom allowed to hold major positions in the Imperial government, or the Prussian government. After 1871, there was a systematic purge of the remaining Catholics; in the powerful interior ministry, which handled all police affairs, the only Catholic was a messenger boy. Jews were likewise heavily discriminated against.^[303][304]

Most of the Kulturkampf was fought out in Prussia, but Imperial Germany passed the Pulpit Law which made it a crime for any cleric to discuss public issues in a way that displeased the government. Nearly all Catholic bishops, clergy, and laymen rejected the legality of the new laws and defiantly faced the increasingly heavy penalties and imprisonments imposed by Bismarck's government. Historian Anthony Steinhoff reports the casualty totals:

As of 1878, only three of eight Prussian dioceses still had bishops, some 1,125 of 4,600 parishes were vacant, and nearly 1,800 priests ended up in jail or in exile ... Finally, between 1872 and 1878, numerous Catholic newspapers were confiscated, Catholic associations and assemblies were dissolved, and Catholic civil servants were dismissed merely on the pretence of having Ultramontane sympathies.^[305]

Bismarck underestimated the resolve of the Catholic Church and did not foresee the extremes that this struggle would attain.^[306][307] The Catholic Church denounced the harsh new laws as anti-Catholic and mustered the support of its rank and file voters across Germany. In the following elections, the Center Party won a quarter of the seats in the Imperial Diet.^[308] The conflict ended after 1879 because Pope Pius IX died in 1878 and Bismarck broke with the Liberals to put his main emphasis on tariffs, foreign policy, and attacking socialists. Bismarck negotiated with the conciliatory new pope Leo XIII.^[309] Peace was restored, the bishops returned and the jailed clerics were released. Laws were toned down or taken back, but the laws concerning education, civil registry of marriages and religious disaffiliation remained in place. The Center Party gained strength and became an ally of Bismarck, especially when he attacked socialism.^[310]

Historians have cited the campaign against the Catholic church, as well as a similar campaign against the Social Democratic Party, as leaving a lasting influence on the German consciousness, whereby national unity can be encouraged by excluding or persecuting a minority. This strategy, later referred to as "negative integration", set a tone of either being loyal to the government or an enemy of the state, which directly influenced German nationalist sentiment and the later Nazi movement.^[311]

Chancellor Bismarck's imperial foreign policy basically aimed at security and the prevention of a Franco-Russian alliance, in order to avoid a likely Two-front war. The League of Three Emperors was signed in 1873 by Russia, Austria, and Germany. It stated that republicanism and socialism were common enemies and that the three powers would discuss any matters concerning foreign policy. Bismarck needed good relations with Russia in order to keep France isolated. Russia fought a victorious war against the Ottoman Empire from 1877 to 1878 and attempted to establish the Principality of Bulgaria, that was strongly opposed by France and Britain in particular, as they were long concerned with the preservation of the Ottoman Empire and Russian containment at the Bosphorus Strait and the Black Sea. Germany hosted the Congress of Berlin in 1878, where a more moderate peace settlement was agreed upon.

In 1879, Germany formed the Dual Alliance with Austria-Hungary, an agreement of mutual military assistance in the case of an attack from Russia, which was not satisfied with the agreement of the Congress of Berlin. The establishment of the Dual Alliance led Russia to take a more conciliatory stance and in 1887, the so-called Reinsurance Treaty was signed between Germany and Russia. In it, the two powers agreed on mutual military support in the case that France attacked Germany or an Austrian attack on Russia. Russia turned its attention eastward to Asia and remained largely inactive in European politics for the next 25 years. In 1882, Italy, seeking supporters for its interests in North Africa against France's colonial policy, joined the Dual Alliance, which became the Triple Alliance. In return for German and Austrian support, Italy committed itself to assisting Germany in the case of a French attack.^[312]

Bismarck had always argued that the acquisition of overseas colonies was impractical and the burden of administration and maintenance would outweigh the benefits. Eventually, Bismarck gave way, and a number of colonies were established in Africa (Togo, the Cameroons, German South-West Africa, and German East Africa) and in Oceania (German New Guinea, the Bismarck Archipelago, and the Marshall Islands). Consequently, Bismarck initiated the Berlin Conference of 1885, a formal meeting of the European colonial powers, who sought to "established international guidelines for the acquisition of African territory" (see Colonisation of Africa). Its outcome, the General Act of the Berlin Conference, can be seen as the formalisation of the "Scramble for Africa" and "New Imperialism".^[313]

Emperor William I died in 1888. His son Frederick III, open for a more liberal political course, reigned only for ninety-nine days, as he was stricken with throat cancer and died three months after his coronation. His son Wilhelm II followed him on the throne at the age of 29. Wilhelm rejected the liberal ideas of his parents and embarked on a conservative autocratic rule. He early on decided to replace the political elite and in March 1890 he forced chancellor Bismarck into retirement.^[314] Following his principle of "Personal Regiment", Wilhelm was determined to exercise maximum influence on all government affairs.^{[315][316][317]}

The young Kaiser Wilhelm set out to apply his imperialist ideas of Weltpolitik (German: [ˈvɛltpoliˌtiːk], "world politics"), as he envisaged a gratuitously aggressive political course to increase the empire's influence in and control over the world. After the removal of Bismarck, foreign policies were tackled with by the Kaiser and the Federal Foreign Office under Friedrich von Holstein. Wilhelm's increasingly erratic and reckless conduct was unmistakably related to character deficits and the lack of diplomatic skills.^[318][319] The foreign office's rather sketchy assessment of the current situation and its recommendations for the empire's most suitable course of action were:

First a long-term coalition between France and Russia had to fall apart, secondly, Russia and Britain would never get together, and finally, Britain would eventually seek an alliance with Germany.

Subsequently, Wilhelm refused to renew the Reinsurance Treaty with Russia. Russia promptly formed a closer relationship with France in the Dual Alliance of 1894, as both countries were concerned about the novel disagreeability of Germany. Furthermore, Anglo–German relations provided, from a British point of view, no basis for any consensus as the Kaiser refused to divert from his, although somewhat peculiarly desperate and anachronistic, aggressive imperial engagement and the naval arms race in particular. Holstein's analysis proved to be mistaken on every point and Wilhelm failed too, as he did not adopt a nuanced political dialogue. Germany was left gradually isolated and dependent on the Triple Alliance, with Austria-Hungary and Italy. This agreement was hampered by differences between Austria and Italy and in 1915 Italy left the alliance.^[250]

In 1897, Admiral Alfred von Tirpitz, state secretary of the German Imperial Naval Office devised his initially rather practical, yet nonetheless ambitious plan to build a sizeable naval force. Although basically posing only an indirect threat as a Fleet in being, Tirpitz theorized, that its mere existence would force Great Britain, dependent on unrestricted movement on the seas, to agree to diplomatic compromises.^[320] Tirpitz started the program of warship construction in 1898 and enjoyed the full support of Kaiser Wilhelm. Wilhelm entertained less rational ideas on the fleet, that circled around his romantic childhood dream to have a "fleet of [his] own some day" and his obsessive adherence to direct his policies along the line of Alfred Thayer Mahan's work The Influence of Sea Power upon History.^[321] In exchange for the eastern African island of Zanzibar, Germany had bargained the island of Heligoland in the German Bight with Britain in 1890, and converted the island into a naval base and installed immense coastal defense batteries. Britain considered the imperial German endeavours to be a dangerous infringement on the century-old delicate balance of global affairs and trade on the seas under British control. The British, however, resolved to keep up the naval arms race and introduced the highly advanced new Dreadnought battleship concept in 1907. Germany quickly adopted the concept and by 1910 the arms race again escalated.^[322][323]

In the First Moroccan Crisis of 1905, Germany nearly clashed with Britain and France when the latter attempted to establish a protectorate over Morocco. Kaiser Wilhelm II was upset at having not been informed about French intentions, and declared their support for Moroccan independence. William II made a highly provocative speech regarding this. The following year, a conference was held in which all of the European powers except Austria-Hungary (by now little more than a German satellite) sided with France. A compromise was brokered by the United States where the French relinquished some, but not all, control over Morocco.^[324]

The Second Moroccan Crisis of 1911 saw another dispute over Morocco erupt when France tried to suppress a revolt there. Germany, still smarting from the previous quarrel, agreed to a settlement whereby the French ceded some territory in central Africa in exchange for Germany's renouncing any right to intervene in Moroccan affairs. This confirmed French control over Morocco, which became a full protectorate of that country in 1912.^[325]

By 1890, the economy continued to industrialize and grow on an even higher rate than during the previous two decades and increased dramatically in the years leading up to World War I. Growth rates for the individual branches and sectors often varied considerably, and periodical figures provided by the Kaiserliches Statistisches Amt ("Imperial Statistical Bureau) are often disputed or just assessments. Classification and naming of internationally traded commodities and exported goods was still in progress and the structure of production and export had changed during four decades. Published documents provide numbers such as: The proportion of goods manufactured by the modern industry was approximately 25% in 1900, while the proportion of consumer related products in manufactured exports stood at 40%.^[326] Reasonably exact are the figures for the entire industrial production between 1870 and 1914, which increased about 500%.^[327]

Historian J. A. Perkins argued that more important than Bismarck's new tariff on imported grain was the introduction of the sugar beet as a main crop. Farmers quickly abandoned traditional, inefficient practices in favor of modern methods, including the use of artificial fertilizers and mechanical tools. Intensive methodical farming of sugar and other root crops made Germany the most efficient agricultural producer in Europe by 1914. Even so, farms were usually small in size and women did much of the field work. An unintended consequence was the increased dependence on migratory, especially foreign, labor.^[328][329]

The basics of the modern chemical research laboratory layout and the introduction of essential equipment and instruments such as Bunsen burners, the Petri dish, the Erlenmeyer flask, task-oriented working principles and team research originated in 19th-century Germany and France. The organisation of knowledge acquisition was further refined by laboratory integration in research institutes of the universities and the industries. Germany acquired the leading role in the world's chemical industry by the late 19th century through strictly organized methodology. In 1913, the German chemical industry produced almost 90 per cent of the global supply of dyestuffs and sold about 80 per cent of its production abroad.^[330][331]

Germany became Europe's leading steel-producing nation in the 1890s, thanks in large part to the protection from American and British competition afforded by tariffs and cartels.^[332] The leading firm was "Friedrich Krupp AG Hoesch-Krupp", run by the Krupp family.^[333] The merger of several major firms into the Vereinigte Stahlwerke (United Steel Works) in 1926 was modeled on the U.S. Steel corporation in the United States. The new company emphasized rationalization of management structures and modernization of the technology; it employed a multi-divisional structure and used return on investment as its measure of success. By 1913, American and German exports dominated the world steel market, as Britain slipped to third place.^[334]

In machinery, iron and steel, and other industries, German firms avoided cut-throat competition and instead relied on trade associations. Germany was a world leader because of its prevailing "corporatist mentality", its strong bureaucratic tradition, and the encouragement of the government. These associations regulate competition and allowed small firms to function in the shadow of much larger companies.^[335]

By the 1890s, German colonial expansion in Asia and the Pacific (Kiauchau in China, the Marianas, the Caroline Islands, Samoa) led to frictions with Britain, Russia, Japan and the United States.^[336] The construction of the Baghdad Railway, financed by German banks, was designed to eventually connect Germany with the Turkish Empire and the Persian Gulf, but it also collided with British and Russian geopolitical interests.^[337]

The largest colonial enterprises were in Africa.^[338] The harsh treatment of the Nama and Herero in what is now Namibia in Africa in 1906–1907 led to charges of genocide against the Germans. Historians are examining the links and precedents between the Herero and Namaqua Genocide and the Holocaust of the 1940s.^{[339][340][341]}

Other claimed territories of the German Colonial Empire are: Bear Island (occupied in 1899),^[342] Togo-Hinterlands,^[343] German Somali Coast,^[344] Katanga Territories, Pondoland (failed attempt by Emil Nagel [de]),^[345] Nyassaland (Mozambique), Southwestern Madagascar,^[346] Santa Lucia Bay (South Africa) (failed attempt in 1884),^[347] and the Farasan Islands.^[348]

Ethnic demands for nation states upset the balance between the empires that dominated Europe, leading to World War I, which started in August 1914. Germany stood behind its ally Austria in a confrontation with Serbia, but Serbia was under the protection of Russia, which was allied to France. Germany was the leader of the Central Powers, which included Austria-Hungary, the Ottoman Empire, and later Bulgaria; arrayed against them were the Allies, consisting chiefly of Russia, France, Britain, and in 1915 Italy.

In explaining why neutral Britain went to war with Germany, author Paul M. Kennedy recognized it was critical for war that Germany become economically more powerful than Britain, but he downplays the disputes over economic trade imperialism, the Baghdad Railway, confrontations in Central and Eastern Europe, high-charged political rhetoric and domestic pressure-groups. Germany's reliance time and again on sheer power, while Britain increasingly appealed to moral sensibilities, played a role, especially in seeing the invasion of Belgium as a necessary military tactic or a profound moral crime. The German invasion of Belgium was not important because the British decision had already been made and the British were more concerned with the fate of France. Kennedy argues that by far the main reason was London's fear that a repeat of 1870 – when Prussia and the German states smashed France – would mean that Germany, with a powerful army and navy, would control the English Channel and northwest France. British policy makers insisted that would be a catastrophe for British security.^[349]

In the west, Germany sought a quick victory by encircling Paris using the Schlieffen Plan. But it failed due to Belgian resistance, Berlin's diversion of troops, and very stiff French resistance on the Marne, north of Paris. The Western Front became an extremely bloody battleground of trench warfare. The stalemate lasted from 1914 until early 1918, with ferocious battles that moved forces a few hundred yards at best along a line that stretched from the North Sea to the Swiss border. The British imposed a tight naval blockade in the North Sea which lasted until 1919, sharply reducing Germany's overseas access to raw materials and foodstuffs. Food scarcity became a serious problem by 1917.^[350] The United States joined with the Allies in April 1917. The entry of the United States into the war – following Germany's declaration of unrestricted submarine warfare – marked a decisive turning-point against Germany.^[351]

Total casualties on the Western Front were 3,528,610 killed and 7,745,920 wounded.^[352]

More wide open was the fighting on the Eastern Front. In the east, there were decisive victories against the Russian army, the trapping and defeat of large parts of the Russian contingent at the Battle of Tannenberg, followed by huge Austrian and German successes. The breakdown of Russian forces – exacerbated by internal turmoil caused by the 1917 Russian Revolution – led to the Treaty of Brest-Litovsk the Bolsheviks were forced to sign on 3 March 1918 as Russia withdrew from the war. It gave Germany control of Eastern Europe. Spencer Tucker says, "The German General Staff had formulated extraordinarily harsh terms that shocked even the German negotiator."^[353] When Germany later complained that the Treaty of Versailles of 1919 was too harsh on them, the Allies responded that it was more benign than Brest-Litovsk.^[354]

By defeating Russia in 1917, Germany was able to bring hundreds of thousands of combat troops from the east to the Western Front, giving it a numerical advantage over the Allies. By retraining the soldiers in new storm-trooper tactics, the Germans expected to unfreeze the Battlefield and win a decisive victory before the American army arrived in strength.^[355] However, the spring offensives all failed, as the Allies fell back and regrouped, and the Germans lacked the reserves necessary to consolidate their gains. In the summer, with the Americans arriving at 10,000 a day, and the German reserves exhausted, it was only a matter of time before multiple Allied offenses destroyed the German army.^[356]

Although war was not expected in 1914, Germany rapidly mobilized its civilian economy for the war effort, the economy was handicapped by the British blockade that cut off food supplies.^[357]

Steadily conditions deteriorated rapidly on the home front, with severe food shortages reported in all urban areas. Causes involved the transfer of many farmers and food workers into the military, an overburdened railroad system, shortages of coal, and especially the British blockade that cut off imports from abroad. The winter of 1916–1917 was known as the "turnip winter", because that vegetable, usually fed to livestock, was used by people as a substitute for potatoes and meat, which were increasingly scarce. Thousands of soup kitchens were opened to feed the hungry people, who grumbled that the farmers were keeping the food for themselves. Even the army had to cut the rations for soldiers.^[358] Morale of both civilians and soldiers continued to sink. According to historian William H. MacNeil:

By 1917, after three years of war, the various groups and bureaucratic hierarchies which had been operating more or less independently of one another in peacetime (and not infrequently had worked at cross purposes) were subordinated to one (and perhaps the most effective) of their number: the General Staff. Military officers controlled civilian government officials, the staffs of banks, cartels, firms, and factories, engineers and scientists, workingmen, farmers-indeed almost every element in German society; and all efforts were directed in theory and in large degree also in practice to forwarding the war effort.^[359]

1918 was the year of the deadly 1918 Spanish Flu pandemic which struck hard at a population weakened by years of malnutrition.

In October 1918, General Ludendorff, who wanted to protect the reputation of the Imperial Army by placing responsibility for the capitulation on the democratic parties and the Imperial Reichstag, pushed for the government to be democratised. A new chancellor was appointed, members of the Reichstag's majority parties were brought into the cabinet for the first time and the constitution modified.^[360] The moves did not, however, satisfy either the Allies or the majority of German citizens.

The German revolution of 1918–1919 began on 3 November with a sailor's mutiny at Kiel which spread rapidly and all but bloodlessly across Germany. Within a week, workers' and soldiers' councils were in control of government and military institutions across most of the Reich.^[361] On 9 November, Germany was declared a republic. The following day, the Council of the People's Deputies, formed from members of Germany's two main socialist parties, began acting as the provisional government. By the end of the month, all of Germany's ruling monarchs, including Emperor Wilhelm II, who had fled to exile in the Netherlands, had been forced to abdicate.^[362]

In early January 1919, the Spartacist uprising led by the newly founded Communist Party of Germany attempted to take power in Berlin, but it was quashed by government and Freikorps troops. Into the spring there were additional violently suppressed efforts to push the revolution further in the direction of a council republic, such as the short-lived local soviet republics, notably in Bavaria (Munich). They too were put down with considerable loss of life.^[363]

The revolution's end is generally set at 11 August 1919, the day the Weimar Constitution was signed following its adoption by the popularly elected Weimar National Assembly, Even though the widespread violence largely ended in 1919, the revolution remained in many ways incomplete. A large number of its opponents had been left in positions of power in the military and the Reich administration, and it failed to resolve the fracture in the Left between moderate socialists and communists. The Weimar Republic as a result was beset from the beginning by opponents from both the Left and – to a greater degree – the Right.^[364]

Under the peace terms of the Treaty of Versailles, Germany's first democracy began its fourteen year life facing territorial losses, reparations to the victors of World War I and stringent limitations on its military. Political violence from those on the Right who wanted a return to the monarchy and those on the Left who wanted a soviet-style regime repeatedly threatened the moderate socialist government through 1923. Ongoing issues with the payment of reparations fuelled the hyperinflation of 1923 that impoverished many Germans and left them bitter enemies of the Republic. A period of relative political and economic stability that lasted until the onset of the Great Depression in 1929 was followed by the rapid growth of parties on the extremes – the Communists on the Left and the Nazis on the Right – that left the Reichstag (parliament) all but unable to function. In quick succession, four chancellors tried and failed to govern by decree before President Hindenburg named Adolf Hitler chancellor in 1933. In only a few months he had turned the Republic into a Nazi dictatorship.

The Armistice of 11 November 1918 ended the fighting in World War I, and on 28 June 1919 Germany reluctantly signed the peace terms laid out in the Treaty of Versailles. Germany had to renounce sovereignty over its colonies^[365] and in Europe lost 65,000 sq km (25,000 sq mi) or about 13% of its former territory – including 48% of its iron and 10% of its coal resources – along with 7 million people, or 12% of its population.^[366] Allied troops occupied the Rhineland, and it along with an area stretching 50 kilometres east of the Rhine were demilitarized.^[367] The German army was limited to no more than 100,000 men with 4,000 officers and no general staff; the navy could have at most 15,000 men and 1,500 officers. Germany was prohibited from having an air force, submarines or dreadnoughts. A large number of its ships and all of its air-related armaments were to be surrendered.^[368][369] The most contentious article of the treaty, the so-called War Guilt Clause (Article 231), stated that Germany accepted full responsibility for all the loss and damage from the war and therefore had to pay reparations to the Allied Powers.^[370]

The treaty was reviled as a dictated rather than a negotiated peace. Philipp Scheidemann, the Social Democratic minister president of Germany, said to the Weimar National Assembly on 12 May 1919, "What hand should not wither that puts this fetter on itself and on us?"^[371]

The Weimar Constitution established a federal semi-presidential republic with a chancellor dependent on the confidence of the Reichstag (parliament), a strong president who had considerable powers to govern by decree,^[372] and a substantial set of individual rights.^[373]The Social Democrat Friedrich Ebert was the Republic's first president.

The Left accused the Social Democrats of betraying the ideals of the labour movement because of their alliance with the old elites in the military and administration, and the Right held the supporters of the Republic responsible for Germany's defeat in the war.^[374] In early 1920, the right-wing Kapp Putsch, backed by units of the paramilitary Freikorps, briefly took control of the government in Berlin, but the putsch quickly collapsed due to a general strike and passive resistance by civil servants.^[375] In the putsch's wake, workers in the industrial Ruhr district, where dissatisfaction with the lack of nationalisation of key industries was particularly high, rose up and attempted to take control of the region. Reichswehr and Freikorps units suppressed the Ruhr uprising with the loss of over 1,000 lives.^[376] The unstable political conditions of the period were reflected in the Reichstag election of 1920, in which the centre-left Weimar Coalition, which until then had held a three-quarters majority, lost 125 seats to parties on both the Left and Right.^[377]

Political violence continued at a high level through 1923. A right-wing extremist group assassinated former finance minister Matthias Erzberger in August 1921 and Walther Rathenau, the Jewish foreign minister, in June 1922.^[378] 1923 saw the communist-led takeover attempt known as the German October, the right-wing Küstrin Putsch and Adolf Hitler's Beer Hall Putsch.

Germany was the first state to establish diplomatic relations with the new Soviet Union in the 1922 Treaty of Rapallo.^[379] In October 1925, Germany, France, Belgium, Britain and Italy signed the Treaty of Locarno, which recognised Germany's borders with France and Belgium but left its eastern borders open to negotiations. The treaty paved the way for Germany's admission to the League of Nations in 1926.^[380]

In May 1921 the Allied Powers set Germany's reparations liability under the terms of the Treaty of Versailles at 132 billion Reichsmarks, to be paid either in gold or commodities such as iron, steel and coal.^[381] After a series of German defaults, French and Belgian troops occupied the Ruhr in January 1923. The German government responded with a policy of passive resistance. It underwrote the costs of idled factories and mines and paid the workers who were on strike. Unable to meet the enormous costs by any other means, it resorted to printing money. Along with the debts the state had incurred during the war, it was one of the major causes of the 1923 peak in Germany's post-war hyperinflation.^[382] The passive resistance was called off in September 1923, and the occupation ended in August 1925, following an agreement (the Dawes Plan) to restructure Germany's reparations.^[383] In November 1923 the government introduced a new currency, the Rentenmark (later the Reichsmark). Together with other measures, it quickly stopped the hyperinflation, but many Germans who lost their life savings became bitter enemies of the Weimar Republic and supporters of the anti-democratic Right.^[384] During the following six years the economic situation improved. In 1928 Germany's industrial production surpassed the pre-war level of 1913.^[385]

In 1925, following the death in office of President Ebert, conservative Field Marshal Paul von Hindenburg was elected to replace him. His presidency, coming after a campaign that emphasised nationalism and Hindenburg's ties to the fallen German Empire, was the beginning of a significant shift to the right in German politics.^[386]

The Wall Street Crash of 1929 marked the beginning of the worldwide Great Depression, which hit Germany as hard as any nation. In 1931 several major banks failed, and by early 1932 the number of unemployed had soared to more than six million.^[387] In the Reichstag election of September 1930, the Communist Party of Germany (KPD) gained 23 seats, while the National Socialist German Workers' Party (NSDAP, Nazi Party), until then a minor far-right party, increased its share by 95 seats, becoming Germany's second largest party behind the Social Democrats.^[388] The Nazis were particularly successful among Protestants, unemployed young voters, the lower middle class in the cities and the rural population. It was weakest in Catholic areas and in large cities.^[389] The shift to the political extremes made the unstable coalition system by which every Weimar chancellor had governed increasingly unworkable. The last years of the Weimar Republic were marred by even more systemic political instability than previous years, and political violence increased. Four chancellors (Heinrich Brüning, Franz von Papen, Kurt von Schleicher and, from 30 January to 23 March 1933, Adolf Hitler) governed through presidential decree rather than parliamentary consultation.^[381] It effectively rendered the Reichstag powerless as a means of enforcing constitutional checks and balances.

Hindenburg was re-elected president in 1932, out-polling Hitler by almost 6 million votes in the second round.^[390] The Nazi Party became the largest party in the Reichstag following the election of July 1932. It received 37% of the vote, with the SPD second (22%) and the Communist KPD third at 14%. The Nazis dropped to 33% after another election four months later, but they remained the largest party. The splintered Reichstag was still unable to form a stable coalition. On 30 January 1933, seeing no other viable option and pressured by former chancellor Franz von Papen and other conservatives, President Hindenburg appointed Hitler chancellor.^[391]

The Weimar years saw a flowering of German science and high culture, before the Nazi regime resulted in a decline in the scientific and cultural life in Germany and forced many renowned scientists and writers to flee. German recipients dominated the Nobel prizes in science.^[392] Germany dominated the world of physics before 1933, led by Hermann von Helmholtz, Wilhelm Conrad Röntgen, Albert Einstein, Otto Hahn, Max Planck and Werner Heisenberg. Chemistry likewise was dominated by German professors and researchers at the great chemical companies such as BASF and Bayer and persons like Justus von Liebig, Fritz Haber and Emil Fischer. Theoretical mathematicians Georg Cantor in the 19th century and David Hilbert in the 20th century. Karl Benz, the inventor of the automobile, and Rudolf Diesel were pivotal figures of engineering, and Wernher von Braun, rocket engineer. Ferdinand Cohn, Robert Koch and Rudolph Virchow were three key figures in microbiology.

Among the most important German writers were Thomas Mann, Hermann Hesse and Bertolt Brecht. The reactionary historian Oswald Spengler wrote The Decline of the West (1918–1923) on the inevitable decay of Western Civilization, and influenced intellectuals in Germany such as Martin Heidegger, Max Scheler, and the Frankfurt School, as well as intellectuals around the world.^[393]

After 1933, Nazi proponents of "Aryan physics", led by the Nobel Prize-winners Johannes Stark and Philipp Lenard, attacked Einstein's theory of relativity as a degenerate example of Jewish materialism in the realm of science. Many scientists and humanists emigrated; Einstein moved permanently to the U.S. but some of the others returned after 1945.^[394][395]

The Nazi regime suppressed labor unions and strikes, leading to prosperity which gave the Nazi Party popularity, with only minor, isolated and subsequently unsuccessful cases of resistance among the German population over their rule. The Gestapo (secret police) destroyed the political opposition and persecuted the Jews, trying to force them into exile. The Party took control of the courts, local government, and all civic organizations except the Christian churches. All expressions of public opinion were controlled the propaganda ministry, which used film, mass rallies, and Hitler's hypnotic speaking. The Nazi state idolized Hitler as its Führer (leader), putting all powers in his hands. Nazi propaganda centered on Hitler and created the "Hitler Myth"—that Hitler was all-wise and that any mistakes or failures by others would be corrected when brought to his attention.^[396] In fact Hitler had a narrow range of interests and decision making was diffused among overlapping, feuding power centers; on some issues he was passive, simply assenting to pressures from whoever had his ear. All top officials reported to Hitler and followed his basic policies, but they had considerable autonomy on a daily basis.^[397]

To secure a Reichstag majority for his party, Hitler called for new elections. After the 27 February 1933 Reichstag fire, Hitler swiftly blamed an alleged Communist uprising, and convinced President Hindenburg to approve the Reichstag Fire Decree, rescinding civil liberties. Four thousand communists were arrested ^[398] and Communist agitation was banned. Communists and Socialists were brought into hastily prepared Nazi concentration camps, where they were at the mercy of the Gestapo, the newly established secret police force. Communist Reichstag deputies were taken into "protective custody".

Despite the terror and unprecedented propaganda, the last free General Elections of 5 March 1933, while resulting in 43.9% failed to give the Nazis their desired majority. Together with the German National People's Party (DNVP), however, he was able to form a slim majority government. On 23 March 1933, the Enabling Act marked the beginning of Nazi Germany,^[399] allowing Hitler and his cabinet to enact laws on their own without the President or the Reichstag.^[400] The Enabling Act formed the basis for the dictatorship and the dissolution of the Länder. Trade unions and all political parties other than the Nazi Party were suppressed. A centralised totalitarian state was established, no longer based on the liberal Weimar constitution. Germany withdrew from the League of Nations shortly thereafter. The coalition parliament was rigged by defining the absence of arrested and murdered deputies as voluntary and therefore cause for their exclusion as wilful absentees. The Centre Party was voluntarily dissolved in a quid pro quo with the Pope under the anti-communist Pope Pius XI for the Reichskonkordat; and by these manoeuvres Hitler achieved movement of these Catholic voters into the Nazi Party, and a long-awaited international diplomatic acceptance of his regime. The Nazis gained a larger share of their vote in Protestant areas than in Catholic areas.^[401] The Communist Party was proscribed in April 1933.

Hitler used the SS and Gestapo to purge the entire SA leadership—along with a number of Hitler's political adversaries in the Night of the Long Knives from 30 June to 2 July 1934.^[402] As a reward, the SS became an independent organisation under the command of the Reichsführer-SS Heinrich Himmler. Upon Hindenburg's death on 2 August 1934, Hitler's cabinet passed a law proclaiming the presidency to be vacant and transferred the role and powers of the head of state to Hitler.

The Nazi regime was particularly hostile towards Jews, who became the target of unending antisemitic propaganda attacks. The Nazis attempted to convince the German people to view and treat Jews as "subhumans"^[403] and immediately after the 1933 federal elections the Nazis imposed a nationwide boycott of Jewish businesses. In March 1933 the first Nazi concentration camp was established at Dachau^[404] and from 1933 to 1935 the Nazi regime consolidated their power. The Law for the Restoration of the Professional Civil Service forced all Jewish civil servants to retire from the legal profession and the civil service.^[405] The Nuremberg Laws banned sexual relations between Jews and Germans and only those of German or related blood were eligible to be considered citizens; the remainder were classed as state subjects, without citizenship rights.^[406] This stripped Jews, Romani and others of their legal rights.^[407] Jews continued to suffer persecution under the Nazi regime, exemplified by the Kristallnacht pogrom of 1938, and about half of Germany's 500,000 Jews fled the country before 1939, after which escape became almost impossible.^[408]

In 1941, the Nazi leadership decided to implement a plan that they called the "Final Solution" which came to be known as the Holocaust. Under the plan, Jews and other "lesser races" along with political opponents from Germany as well as occupied countries were systematically murdered at murder sites, and starting in 1942, at extermination camps.^[409] Between 1941 and 1945 Jews, Gypsies, Slavs, communists, homosexuals, the mentally and physically disabled and members of other groups were targeted and methodically murdered – the origin of the word "genocide". In total approximately 11 million people were killed during the Holocaust.^[410]
