Ancient Chinese states



Ancient Chinese states were dynastic polities of China within and without the Zhou cultural sphere prior to Qin's wars of unification. They ranged in size from large estates, to city-states to much vaster territories with multiple population centers. Many of these submitted to royal authority, but many did not—even those that shared the same culture and ancestral temple surname as the ruling house. Prior to the Zhou conquest of Shang, the first of these ancient states were already extant as units of the preceding Shang dynasty, Predynastic Zhou, or polities of other cultural groups. Once the Zhou had established themselves, they made grants of land and relative local autonomy to kinfolk in return for military support and tributes, under a system known as fengjian.

The rulers of the states were collectively the zhuhou. Over the course of the Zhou dynasty (c. 1046–256 ), the ties of family between the states attenuated, the power of the central government waned, and the states grew more autonomous. Some regional rulers granted subunits of their own territory to ministerial lineages who eventually eclipsed them in power and in some cases usurped them. Over time generally the smaller polities were absorbed by the larger ones, either by force or willing submission, until only one remained: Qin, which unified the realm in 221 and became China's first imperial dynasty.

Shang dynasty
Fang States (Chinese:⽅) refer to the various tribes and states during the Shang dynasty in ancient China. Today, scholars' understanding of these states primarily comes from oracle bone inscriptions unearthed from the late Shang dynasty Yinxu. In these inscriptions, these tribal states are often referred to as name + "方". In modern style Chinese the term can be duplicated to Fang Guo (Traditional Chinese:⽅國).

Western Zhou
Following the overthrow of the Shang dynasty in 1046 BCE, the early kings made hereditary land grants to various relatives and descendants. Along with the land and title came a responsibility to support the Zhou king during an emergency and to pay ritual homage to the Zhou ancestors. In the Yellow River valley, of the earliest vassal states, the state of Cai was founded following a grant of land by the conquering King Wu of Zhou to a younger brother. Other states established at this time included Cao, Yan , Jin , and Chen. The state of Song was permitted to be retained by the nobility of the defeated Shang dynasty, in what would become a custom known as Er Wang San Ke. In the Zhou heartland of the Wei River valley, most existing polities submitted to Zhou overlordship, although the state of Yu did not, since their rulers belonged to a more senior branch of the lineage group than the Zhou kings. The rulers of the state of Guo also belonged to a different branch lineage, but they submitted to royal authority. The relation of the polities in the old Zhou heartland to the royal court was informed by the preexisting kinship structures amongst them, whereas the relationship between the newly established regional states and the royal court was more directly political.

On the periphery, the states of Yan, Qi, and Jin in the north and northeast had more room to expand and grew into large states. In the southwest the non-Zhou state of Chu demanded attention. In the southeast, the Zhou confederation was bordered by the peoples of Wu and Yue. These polities and cultural outgroups in the Yangtze River valley were not fully incorporated into a centralised political domain until the imperial era. Around the borders of the Central States lived "barbarians", fenced off from the Zhou heartlands by their enfeoffed regional lords. Apart from their responsibilities to the throne, the regional lords were responsible for their families, their people, and the altars of soil and grain outside their cities, where annual sacrifices were performed.

Over time the parcels of land the royal court was able to grant became increasingly small, and population growth and associated socioeconomic pressures strained the Zhou confederation and the power of the central government. Canny clans formed alliances through marriage, powerful ministers began to overshadow the kings, and eventually a succession crisis brought an end to the Western Zhou period.

Spring and Autumn period
After an attack by Quanrong nomads allied with several vassal states including Shen and Zheng  in 771 BCE, the Zhou ruler King You was killed in his palace at Haojing. His son fled east and was enthroned by several vassal leaders as King Ping of Zhou. Traditionally, the flight to the east and establishment of the new king is written as if it proceeded very rapidly, but excavated manuscripts hold clues that a parallel king may have reigned for over twenty years, and there may have been no recognized king for nine years. The scale of the division of loyalties between the regional states, and the effect it had on society is not clear, but archaeology attests significant movement of people around this time.

With the primary capital moved from Haojing to Luoyi, after a succession crisis of indeterminate severity, the royal house had lost its power and almost all of its land. The prestige of the king, as Heaven's eldest son, was not significantly diminished, and he retained his ritual authority within the Ji lineage, but he and his family were much more reliant on the regional states. Conversely, the rulers of the states had much less use for the king and his court. Whole lineage groups had moved around under socioeconomic stress, border groups not associated with the Zhou culture gained in power and sophistication, and the geopolitical situation demanded increased contact and communication.

The regional states, now operating more autonomously than ever, had to invent ways to interact diplomatically, and they began to systematize a set of ranks amongst them, meet for interstate conferences, build great walls of rammed earth, and absorb one another.

Hegemons


As the power of the Zhou kings weakened, the Spring and Autumn period saw the emergence of hegemon-protectors who protected the royal house and gave tribute to the king's court, while underwriting the remainder of the confederation with their military might. First among equals, they held power over all other states to raise armies and attack mutual enemies, and extracted tribute from their peers. Meetings were held between the current hegemon and the rulers of the states where ritual ceremonies took place that included swearing of oaths of allegiance to the current Zhou king and to each other.

Between c. 600 BCE and c.  500 BCE a four-way balance of power emerged between Qin in the west, Jin in the north-center, Chu in the south, and Qi in the east whilst a number of smaller states continued to exist between Jin and Qi. The state of Deng was overthrown by Chu in 678 BCE followed by Qin's annexation of Hua  in 627 BCE, establishing a pattern that would gradually see all smaller states eliminated. Towards the end of the Spring and Autumn period wars between states became increasingly common.

Partition of Jin
Regional lords had begun the practice of granting lands of their own to powerful ministerial lineages. Over generations, in some places these ministerial lineages had grown more powerful than their lords. In Jin, a full-scale civil war between 497 and 453 BCE ended with the elimination of most noble lines; the remaining aristocratic families divided Jin into three successor states: Han, Wei , and Zhao.

Warring States period
As the powerful states absorbed more of their neighbours, so too did they centralize their internal power, increasing bureaucratization and reducing the power of the local aristocracy. A new class of gentlemen-scholars, distantly related to the aristocracy but part of the elite culture nonetheless, formed the basis of this extended bureaucracy, their goal of upward social mobility expressed through participation in officialdom.

By about 300 BCE, only seven main states remained: Chu, Han, Qi, Qin, Yan, Wei and Zhao. Some of these built rammed earth walls along their frontiers to protect themselves both from the other states and raids by nomadic tribes like the Quanrong and Xiongnu. Smaller states like Zheng and Song were absorbed by their more powerful neighbors. The non-Zhou states of Ba and Shu  were both conquered by Qin by 316 BCE. All the other states gradually followed suit until Zhou rule finally collapsed in 256 BCE. Against this backdrop, polities also continued to emerge, as in the case of Zhongshan in the north, which was established by the nomadic Bai Di (白翟) in the 400s BCE and would last until 295 BCE.

Qin dynasty
Following Qin's wars of unification, the first emperor Qin Shi Huang eliminated noble titles which did not conform to his ideals of governance, emphasizing merit over than the privileges of birth. He forced all the conquered leaders to attend the capital where he seized their states and turned them into administrative districts classified as either commanderies or counties depending on their size. The officials who ran the new districts were selected on merit rather than by family connections.

Han dynasty
In the early years of the Han dynasty, the commanderies established during the Qin dynasty once more became vassal states in all but name. Emperor Gaozu (r. 202–195 ) granted virtually autonomous territories to his relatives and a few generals with military prowess. Over time these vassal states grew powerful and presented a threat to the ruler. Eventually, during the reign of Emperor Jing (r. 156–141 ), his political advisor Chao Cuo recommended the abolition of all fiefdoms, a policy that led in 154 to the Rebellion of the Seven States. The Prince of Wu Liu Bi (劉濞) revolted first and was followed by the rulers of six further states. The rebellion continued for three months until it was finally quelled. Later, Emperor Wu further weakened the power of the vassal states by eliminating many fiefdoms and restoring central control over their prefectures and counties.
