The decline of feudalism

The most obvious change in political institutions was that the old feudal structure was replaced by systems of incipient bureaucracy under monarchy. The decline of feudalism took its course in the Chunqiu period, and the rise of the new order may be seen in the Zhanguo period. The Zhou feudalism suffered from a continual dilution of authority. As a state expanded, its nobility acquired vassals, and these in turn acquired their own vassals. The longer this went on, the more diluted the family tie became and the more dependent the ruler became on the combined strength of the vassals. At a certain point, the vassals might acquire an advantageous position, and the most dominant figures among them might eclipse the king. The Zhou royal house perhaps reached the turning point earlier than the other feudal states. As a result, the Zhou royal domain and its influence shrank when Pingwang moved his court to the east. The ruling houses of other states suffered the same fate. Within a century after the Zhou court had moved to the east, the ruling houses in most of the feudal states had changed. In some cases a dominating branch replaced the major lineage, and in others a powerful minister formed a strong vassaldom and usurped the authority of the legitimate ruler. Bloody court intrigues and power struggles eliminated many established houses. The new power centers were reluctant to see the process continue and therefore refused to allow further segmentation and subinfeudation. Thus, the feudal system withered and finally collapsed.

Urbanization and assimilation

Simultaneous with the demise of feudalism was a rise in urbanization. Minor fortified cities were built, radiating out from each of the major centers, and other towns radiated from the minor cities. From these cities and towns orders were issued, and to them the resources of the countryside were sent. The central plain along the Huang He was the first to be saturated by clusters of cities. This is probably the reason why the central states soon reached the maximum of their influence in the interstate power struggle: unlike the states in peripheral areas, they had no room to expand.

The period of urbanization was also a time of assimilation. The non-Zhou population caught in the reach of feudal cities could not but feel the magnetic attraction of the civilization represented by the Zhou people and Zhou feudalism. The bronze inscriptions of the Xi Zhou period (1046–771 bce) refer to the disturbances of the outside tribes, who could be found practically everywhere. They were the non-Zhou groups scattered in the open spaces. The outside tribes in inland China were forced to integrate with one or another of the contenders in the interstate conflicts. Their lands were annexed, and their populations were moved or absorbed. The strength of the large states owed much to their success at incorporating these non-Chinese groups. By the time of the unification of China in the 3rd century bce, there was virtually no significant concentration of non-Chinese groups north of the Yangtze River valley and south of the steppe. Bronze pieces attributable to non-Zhou chiefs in the late Chunqiu period show no significant difference in writing system and style from those of the Chinese states.

Zhou civilization was not assimilated so easily in the south, where the markedly different Chu culture flourished. For some centuries, Chu was the archenemy of the Chinese states, yet the nobles of the Chu acquired enough of the northern culture to enable their envoy to the courts of the north to cite the same verses and observe the same manners. The Chu literature that has survived is the fruit of these two distinctive heritages.

To the north were the nomadic peoples of the steppe. As long as they remained divided, they constituted no threat; however, when they were under strong leaders, able to forge a united nomadic empire challenging the dominance of the Chinese, there were confrontations. The “punitive” action into the north during the reign of Xuanwang (827–782 bce) does not seem to have been very large in scope; both sides apparently had little ambition for territorial aggrandizement. Cultural exchange in the northern frontier region was far less than the assimilation that occurred in the south along the Yangtze valley, and it was mainly concerned with techniques of cavalry warfare.
