List of wars: 1900–1944

Graph of global conflict deaths from 1900 to 1944 from various sources.

This is a list of wars that began between 1900 and 1944.

This period saw the outbreak of World War I (1914–1918) and World War II (1939–1945), which are among the deadliest conflicts in human history, with many of the world's great powers partaking in total war and some partaking in genocides. Depending on the source consulted, conflict deaths reached an all-time peak in either 1941 or 1942 at 2.96–7.71 million, during the height of the latter conflict.[1]

Besides the aforementioned world wars, a number of smaller conflicts also took place. In Africa, conflicts of this era were mostly fought between European colonial forces on one side and native kingdoms and insurgents on the other. There are exceptions (e.g. the Italo-Turkish War, as well as intercolonial invasions of English, German, Italian and Vichy French possessions in the World Wars). Likewise, there were several large native rebellions in Southeast Asia against the European, Japanese and American colonial empires. The intercolonial Pacific War of World War II brought many countries into conflict in that theatre.

Other parts of Afro-Eurasia, as well as the Americas, saw a wide variety of conventional wars, civil wars, ethnic or political conflicts, revolutions, and small rebellions. Prior to 1940, Australia saw only sporadic conflict as the frontier wars entered its final stages. However, in World War II, Australia became the site of Axis naval activity and air raids.
