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

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 ( 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, 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.

in 1046 BCE, the early kings made hereditary land grants to various relatives and descendants.

() 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 600 BCE and 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

. Smaller states like Zheng and Song were absorbed by their more powerful neighbors. The non-Zhou states of

Transition from Qin to Han
Han dynasty

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.
