Dynastic cycle

Dynastic cycle (traditional Chinese: 朝代循環; simplified Chinese: 朝代循环; pinyin: Cháodài Xúnhuán) is an important political theory in Chinese history. According to this theory, each dynasty of China rises to a political, cultural, and economic peak and then, because of moral corruption, declines, loses the Mandate of Heaven, and falls, only to be replaced by a new dynasty. The cycle then repeats under a surface pattern of repetitive motifs.^[1]

It sees a continuity in Chinese history from early times to the present by looking at the succession of empires or dynasties, implying that there is little basic development or change in social or economic structures.^[2] John K. Fairbank expressed the doubts of many historians when he wrote that "the concept of the dynastic cycle... has been a major block to the understanding of the fundamental dynamics of Chinese history."^[3]

The cycle appears as follows:^[4]

1. A new ruler founds a new dynasty, and gains the Mandate of Heaven.^[5]
2. China, under the new dynasty, achieves prosperity.
3. The population increases.
4. Corruption becomes rampant in the imperial court, and the empire begins to enter decline and instability.
5. A natural disaster wipes out farm land. The disaster normally would not have been a problem; however, together with the corruption and overpopulation, it causes famine.^[5]
6. The famine causes the population to rebel and a civil war ensues.^[5]
7. The ruler loses the Mandate of Heaven.^[5]
8. The population decreases because of the violence.^[6]
9. China goes through a warring states period.^[6]
10. One state becomes the victor.
11. The state starts a new empire.^[5]
12. The empire gains the Mandate of Heaven.^[5]

(The cycle repeats itself.)

The Mandate of Heaven was the idea that the monarch was favored by Heaven to rule over China. The Mandate of Heaven explanation was championed by the Chinese philosopher Mencius during the Warring States period.^[5]

It has 3 main phases:

1. The first is the beginning of the dynasty.
2. The second is at the middle of the dynasty's life and is the peak of the dynasty.
3. The last period is the decline of the dynasty, both politically and economically, until it finally collapses.

Chinese history is traditionally represented in terms of dynastic cycles. According to the Zhou, Yu the Great established the Xia dynasty because Heaven had given him the authority ages earlier. Heaven retracted its decree and gave it to the Shang instead of the Xia when a terrible monarch appeared among them. The Zhou asserted that Heaven was giving them the mandate since Shang rule had also degraded. The idea of a dynasty cycle would become essential to traditional Chinese political philosophy in later periods. While the Qin rejected the dynastic cycle model, some Han-period historians like Ban Gu re-embraced the dynastic model with works like the Book of Han, which were regarded as adhering to the correct historical framework established by Confucius, in contrast to Sima Qian's Shiji. The Book of Han would set the model for following dynastic histories.^[7]

The Tang was an important period for the evolution of the Chinese historiographical tradition. There were previously various other competing historical visions. Despite being an empire, the Tang chose to institutionalize a historical perspective based on the Book of Documents and the Spring and Autumn Annals. The writing of history became an official imperial undertaking during the Tang period, in contrast to the more or less individualistic histories of Sima Qian and Ban Gu during the Han period. Writing histories covering the time from the fall of the Han to the establishment of the Tang was one of these undertakings. Each of these states was described as a dynasty that rose and fell in accordance with the moral deeds of its founding and final rulers, respectively. These were all written within a dynastic framework. The main inspiration for producing these histories was Ban Gu's Book of Han.^[8]

Through its long history, the Chinese people have been ruled not by one dynasty, but by a succession of different dynasties. The first orthodox dynasty of China to be described in ancient historical records such as Shiji and Bamboo Annals is the Xia, which was succeeded by the Shang, although concrete existence of the Xia is yet to be archaeologically proven.

Among these dynasties the Han and Tang are often considered as particularly strong periods, although other dynasties are famous for cultural and other achievements (for instance, the Song dynasty is sometimes associated with rapid economic development). Han and Tang, as well as other long, stable dynasties, were followed by periods of disorder and the break-up of China into small regimes.

Out of disorder a leader eventually arose who unified the country and imposed strong central authority. For example, after the Han various dynasties ruled parts of China until Yang Jian reunited China under the Sui dynasty. The Sui set the scene for the long and prosperous Tang. After the fall of Tang, China again saw a period of political upheaval.

There is a famous Chinese proverb expressed in the 16th-century novel Romance of the Three Kingdoms that says "After a long split, a union will occur; after a long union, a split will occur" (分久必合，合久必分). Each of these rulers would claim the Mandate of Heaven to legitimize their rule.

Although this well-known dynastic periodization of China is more or less based on traditional Sinocentric ideology, it also applies to non-native rulers who sought to gain the Mandate of Heaven. While most ruling dynasties in Chinese history were founded by ethnic Han, there were also dynasties established by non-Han peoples beyond the traditional border of China proper dominated by Han people. These include the Yuan founded by Mongols and the Qing founded by Manchus, who later conquered China proper and assumed the title of Emperor of China.
