Spring and Autumn period
period in Chinese history from approximately 770 to 476 BCE
The Spring and Autumn period (c. 770 – c. 481 BCE) was a period in Chinese history corresponding roughly to the first half of the Eastern Zhou (c. 771 – 256 BCE), characterized by the gradual erosion of royal power as local lords nominally subject to the Zhou exercised increasing political autonomy. The period's name derives from the Spring and Autumn Annals, a chronicle of the state of Lu between 722 and 481 BCE, which tradition associates with Confucius (551–479 BCE).
During this period, local polities negotiated their own alliances, waged wars against one another, up to defying the king's court in Luoyi. The gradual Partition of Jin, one of the most powerful states, is generally considered to mark the end of the Spring and Autumn period and the beginning of the Warring States period. The periodization dates to the late Western Han (c. 48 BCE – 9 CE).
Background
In 771 BCE, a Quanrong invasion in coalition with the states of Zeng and Shen—the latter polity being the fief of the grandfather of the disinherited crown prince Yijiu—destroyed the Western Zhou capital at Haojing, killing King You and establishing Yijiu as king at the eastern capital Luoyi.
This brief starts where responsible research should: with the source description of “Spring and Autumn period” as period in Chinese history from approximately 770 to 476 BCE. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as period in Chinese history from approximately 770 to 476 BCE. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 2, 2026. The linked authority identifier is Q185047. The Library of Congress control number is sh85024037. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
