the big states usurpers replaced the old rulers. When the chaos ended, there were seven major powers and half a dozen minor ones. Among the seven major powers, Zhao, Han, and Wei had formerly been parts of Jin; the Qi ruling house had changed hands; and Qin was undergoing succession problems. The only “old” state was Chu. Even Chu, a southern state, had become almost completely assimilated to the northern culture (except in art, literature, and folklore). The minor powers had also changed: some had retained only small portions of their old territories, some had new ruling houses, and some were new states that had emerged from non-Chinese tribes. The long interval of power struggle that followed (475–221 BC) is known as the Zhanguo (Warring States) period.

Social, political, and culTural changeS

The years from the 8th century BC to 221 BC witnessed the painful birth of a unified China. It was a period of bloody wars and also of far-reaching changes in politics, society, and intellectual outlook.

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 centres 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 centres, 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 BC) refer to the disturbances of the barbarians, who could be found practically everywhere. They were the non-Zhou groups scattered in the open spaces. The barbarians 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 BC, 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 BC) 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.

The Rise of Monarchy

Internal political changes also took place as states grew in population and area. The most basic of these was in the pattern of power delegation. Under feudalism,

authority had been delegated by the lord to the vassal. The new state rulers sought ways of maintaining and organizing their power.

In the state of Jin the influence of kinsmen of the ruling house had been trimmed even before Wengong established his overlordship. Wengong reorganized the government, installing his most capable followers in the key posts. He set up a hierarchical structure that corresponded to the channels of military command. Appointments to these key positions came to be based on a combination of merit and seniority, thus establishing a type of bureaucracy that was to become traditional in Chinese government.

The Chu government was perhaps the oldest true monarchy among all the Chunqiu states. The authority of the king was absolute. Chu was the only major state in which the ruling house survived the chaotic years of the Zhanguo period.

Local administration went through a slow evolution. The prefecture system developed in both Jin and Chu was one innovation. In Jin there were several dozen prefects across the state, each having limited authority and tenure. The Jin prefect was no more than a functionary, in contrast to the feudal practice. Similar local administrative units grew up in Chu. New lands taken by conquest were organized into prefectures governed by ranking officials who were evidently appointed by the king. The prefecture system of Jin and Chu was to become the

principal form of local administration in the Zhanguo period.

By that time, practically all the major states had chancellors, who acted as leaders of the courts, which were composed of numerous officials. Whereas in the feudal state the officials had been military officers, the more functionally differentiated court of the Zhanguo period usually had a separate corps of civil service personnel. Local administration was entrusted to prefects, who served limited terms. Prefects were often required to submit annual reports to the court so that the ruler could judge their performance. Regional supervisors were sometimes dispatched to check the work of the prefects, a system developed by the later Chinese imperial government into the “censor” system. Fiefs of substantial size were given to only a few people, usually close relatives of the ruler. There was little opportunity for anyone to challenge the sovereignty of the state. The majority of government employees were not relatives of the ruler, and some of them might not even have been citizens of the state. Officials were paid in grain or perhaps in a combination of cash and grain. Archives were kept by scribes on wooden blocks and bamboo strips. These features combined indicate the emergence of some form of bureaucracy.

The new pattern was the result of the efforts of many reformers in different states. Both practical men and theoreticians helped to form the emerging structure, which, though still crude, was

the forerunner of the large and complex bureaucracy of later Chinese dynasties.

Military technique also underwent great changes in the Zhanguo period. In the feudal era, war had been a profession of the nobles. Lengthy training was needed to learn how to drive and shoot from a chariot drawn by horses. There was also an elaborate code of behaviour in combat. The nature of war had already changed by the late Chunqiu period, as the nobility had given way to professional warriors and mercenaries. In some states, special titles of nobility were created for successful warriors, regardless of their origin. Foot soldiers were replacing war chariots as the main force on the battlefield: the expansion of the major states into mountainous areas and the rise of the southern powers in an area of swamps, lakes, and rivers increased the importance of the infantry.

Battles were fought mostly by hordes of foot soldiers, most of them commoners, aided by cavalry units; war chariots apparently served only auxiliary roles, probably as mobile commanding platforms or perhaps as carriers. All of the Zhanguo powers seem to have used conscription systems to recruit able-bodied male citizens. The organization, training, and command of the infantry required experts of a special type, and professional commanders emerged who conducted battles involving several thousand men along lines extending hundreds of miles. A few treatises on the principles of warfare still survive, including Bingfa (The Art of War) by Sunzi. Cavalry warfare

developed among the northern states, including Qin, Zhao, and Yan. The Qin cavalrymen were generally drawn from the northern and northwestern border areas, where there were constant contacts with the steppe peoples. The rise of Yan from a rather obscure state to a major power probably owed much to its successful adoption of cavalry tactics, as well as to its northern expansion.

Economic Development

Important changes occurred in agriculture. Millet had once been the major cereal crop in the north, but wheat gradually grew in importance. Rice, imported from the south, was extended to the dry soil of the north. The soybean, in a number of varieties, proved to be one of the most important crops. Chinese farmers gradually developed a kind of intensive agriculture. Soil was improved by adding manure and night soil. Planting fields in carefully regulated rows replaced the fallow system. Great importance was placed on plowing and seeding at the proper time (especially in the fine-grained loess soil of northern China). Fields were weeded frequently throughout the growing season. Farmers also knew the value of rotating crops to preserve the fertility of the soil, and soybeans were often part of the rotation. Although iron was used to cast implements in the 5th century BC (probably even as early as the 8th century BC), those early examples discovered by archaeologists are of rather inferior quality.

Irrigation became necessary as population pressure forced cropland to be expanded, and irrigation works were constructed in many states beginning in the late Chunqiu period. These projects were built to drain swampy areas, leach out

alkaline soil and replace it with fertile topsoil, and, in the south and in the Sichuan Basin, to carry water into the rice paddies. The irrigation systems unearthed by archaeologists indicate that these were small-scale works carried

out for the most part by state or local authorities.

Another significant change in the economic sphere was the growth of trade among regions. Coins excavated in scattered spots show by their great variety that active trade had expanded into all parts of Zhou China. Great commercial centres had arisen, and the new cities brought a demand for luxuries. The literary records as well as the archaeological evidence show that wealthy persons had possessions made of bronze and gold, silver inlays, lacquer, silk, ceramics, and precious stones. The advancement of ferrous metallurgy led to the earliest recorded blast furnace and the earliest steel. The Chinese had been casting bronze for more than a millennium; turning to iron, they became highly skilled at making weapons and tools. The Han historian Sima Qian (writing c. 100 BC) told of individuals making fortunes in the iron industry.

As the old feudal regimes collapsed and were replaced by centralized monarchies during the Zhanguo period, the feudal nobility fell victim to power struggles within the states and to conquest by stronger states. During the Chunqiu period these parallel processes drastically reduced the numbers of the nobility.

A new elite class arose in the late Chunqiu, composed of the former shi class and the descendants of the old nobility. The members of this class were distinguished by being educated, either in the literary tradition or in the military

arts. The shi provided the administrators, teachers, and intellectual leaders of the new society. The philosophers Confucius (551–479 BC), Mencius (c. 372–289 BC), Mozi (Mo-tzu; 5th century BC), and Xunzi (Hsün-tzu; c. 300–c. 230 BC) were members of the shi class, as was also a large proportion of high-ranking officials and leaders of prominence. The interstate competition that drove rulers to select the most capable and meritorious individuals to serve in their courts resulted in an unprecedented degree of social mobility.

The populace, most of whom were farmers, also underwent changes in status. In feudal times the peasants had been subjects of their lords. They owned no property, at most being permitted to till a piece of the lord’s land for their own needs. The ancient texts tell of the “wellfield” system, under which eight families were assigned 100 mu (15 acres, or 6 hectares) each of land to live on while collectively cultivating another 100 mu as the lord’s reservation. Individual ownership grew as farming became more intensive, and, increasingly, farmers were taxed according to the amount of land they “owned.” The land tax had become a common practice by Zhanguo times. By paying taxes, the tiller of the field acquired the privilege of using the land as his own possession, which perhaps was the first step toward private ownership. As states expanded and new lands were given to cultivation, an increasing number of “free” farmers were to be found tilling land that had never been part of a lord’s manor. With the collapse of
