The role of Wu was extremely important: it marked the beginning of the progressive Sinicization of the region south of the Yangtze River, which before that time had been a frontier area inhabited mainly by non-Chinese tribal peoples. The rise of Jianye (renamed Jiankang during Jin times) as a great administrative and cultural centre on the lower Yangtze paved the way for future developments: after the north was lost to barbarian invaders (311), it was to become the capital of Chinese successor states and an important locus of Chinese culture for more than 250 years.
The Xi (Western) Jin (ad 265–316/317)
The Xi Jin was a period of relative order and prosperity, a short interlude between the turbulent age of the Sanguo and the devastating barbarian invasions. The empire had been nominally reunited (ad 280), and for a short time the central government attempted important fiscal and political reforms, mainly intended to curb the great families that threatened the ruler’s authority. Contacts with the oasis kingdoms of Central Asia and the Indianized states of the far south (Funan and Champa) were resumed, and in 285 the Jin court even sent an envoy to distant Fergana in Central Asia to confer the title of king on its ruler—a grand imperial gesture reminiscent of the great days of Han. But this ghost of the Han empire disappeared almost as soon as it had been evoked. Within two decades the Jin disintegrated through the struggles of rival clans. There followed an internecine war between the various Sima princes, collapse of the central government, decentralized military control of the provinces, famine, large-scale banditry, and messianic peasant movements.
The era of barbarian invasions and rule
For the first time the power vacuum was filled by non-Chinese forces. In 304 a Sinicized Xiongnu chieftain, Liu Yuan, assumed the title of king of Han and started the conquest of northern China. Operating from bases in western and southern Shanxi, the Xiongnu armies, supported by local Chinese rebels, conquered the ancient homeland of Chinese civilization; the fall and destruction of the two capitals, Luoyang (311) and Chang’an (316), ended Chinese dynastic rule in the north for centuries. Although in the far northeast, in present-day Gansu, and in the inaccessible interior (Sichuan), Chinese local kingdoms did occasionally succeed in maintaining themselves for some time, the whole North China Plain itself became the scene of a bewildering variety of barbarian states, collectively known in Chinese historiography as the Shiliuguo (Sixteen Kingdoms).
The Dong (Eastern) Jin (317–420) and later dynasties in the south (420–589)
During the entire medieval period the lower Yangtze region—the former territory of Wu—remained the stronghold of a series of “legitimate” Chinese dynasties, with Jiankang as their capital. In 317 a member of the Jin imperial family had set up a refugee regime at Jiankang, consisting mainly of members of the exiled northern aristocracy. From the beginning the Jin court was completely at the mercy of the great landowning families. Government in the Chinese south became a kind of oligarchy exercised by ever-changing groups and juntas of aristocratic clans. The so-called Six Dynasties were politically and militarily weak and constantly plagued by internal feuds and revolts. (The six were actually five—Dong Jin, 317–420; Liu-Song, 420–479; Nan [Southern] Qi, 479–502; Nan Liang, 502–557; and Nan Chen, 557–589—and all but Dong Jin are also known as Nanchao [Southern Dynasties] in Chinese history; the earlier kingdom of Wu, 222–280, is counted as the sixth dynasty.) Their annihilation (in 589) was postponed only by the internal division of the north and by the protection afforded by the Yangtze. To the very end, their opposition to the north remained alive, but occasional attempts to reconquer the ancient homeland were doomed to failure. The final reunification of China was to start from the northern plains, not from Jiankang.
Although politically insecure, these dynasties were characterized by cultural brilliance: in literature, art, philosophy, and religion, they constituted one of the most creative periods in Chinese history. They reached their highest flowering under the long and relatively stable reign of the great protector of Buddhism, Wudi (reigned 502–549), the first emperor of the Nan Liang dynasty.
The Shiliuguo (Sixteen Kingdoms) in the north (303–439)
The term Sixteen Kingdoms traditionally denotes the plethora of short-lived non-Chinese dynasties that from 303 came to rule the whole or parts of northern China. Many ethnic groups were involved, including ancestors of the Turks (such as the Xiongnu, possibly related to the Huns of late Roman history, and the Jie), the Mongolians (Xianbei), and the Tibetans (Di and Qiang). Most of these nomadic peoples, relatively few in number, had to some extent been Sinicized long before their ascent to power. Some of them—notably the Qiang and the Xiongnu—actually had been allowed to live in the frontier regions within the Great Wall since late Han times.

The barbarian rulers thus set up semi-Sinicized states, in which the foreign element constituted a military aristocracy and the nucleus of the armed forces. Since they lacked experience in administrative matters and since their own tribal institutions were not adapted to the complicated task of ruling a large agrarian society, they had to make use of traditional Chinese ways of government. In doing so, they faced the dilemma that has ever since confronted foreign rulers on Chinese soiclass="underline" the tension that existed between the need to preserve their own ethnic identity (and their position as herrenvolk) on the one hand and on the other the practical necessity of using Chinese literati and members of prominent Chinese families in order to rule at all. In spite of various and sometimes highly interesting experiments, most of these short-lived empires did not survive this tension. Significantly, the only one that proved to have more lasting power and that was able to unify the whole of northern China—the Tuoba, or Bei (Northern) Wei (386–534/535)—was largely Sinicized within a century. In the late 5th century the court even forbade the use of the original Tuoba language, dress, customs, and surnames. This policy of conscious acculturation was further symbolized by the transfer of the Bei Wei capital from the northern frontier region to the ancient imperial residence of Luoyang.
Thus, toward the end of the period of division, the north had become more homogeneous as the result of a long process of adaptation. The most important factor in this process may have been the rehabilitation of the Chinese agrarian economy under the Bei Wei, stimulated by fiscal reform and redistribution of land (c. ad 500). The landed gentry again became the backbone of society, and the rulers of nomadic origin simply had to conform to their way of life. Another factor was the perceived intrinsic superiority of Chinese upper-class culture: in order to play the role of the “son of heaven,” the leaders of the barbarian court had to adopt the complicated rules of Chinese ritual and etiquette. Likewise, in order to surround themselves with an aura of legitimacy, the foreign conquerors had to express themselves in terms of Chinese culture. In doing so, they invariably lost their own identity. History has constantly repeated itself: in this respect the 4th- and 5th-century Jie and Tuoba were but the forerunners of the Qing, or Manchu, rulers in the 19th century.
