Spring and Autumn period

The Spring and Autumn period (simplified Chinese: ; traditional Chinese: ; pinyin: Chūnqiū Shídài) was a period in Chinese history from approximately 771 to 476 BC (or according to some authorities until 403 BC) which corresponds roughly to the first half of the Eastern Zhou dynasty. The period's name derives from the Spring and Autumn Annals, a chronicle of the state of Lu between 722 and 479 BC, which tradition associates with Confucius.

During this period, the Zhou royal authority over the various feudal states started to decline, as more and more dukes and marquesses obtained de facto regional autonomy, defying the king's court in Luoyi, and waging wars amongst themselves. The gradual Partition of Jin, one of the most powerful states, marked the end of the Spring and Autumn period, and the beginning of the Warring States period.

In 771 BC, the Quanrong invasion destroyed the Western Zhou and its capital Haojing, forcing the Zhou king to flee to the eastern capital Luoyi (Chinese: 洛邑). The event ushered in the Eastern Zhou dynasty, which is divided into the Spring and Autumn and the Warring States periods. During the Spring and Autumn period, China's feudal system of fengjian (封建) became largely irrelevant. The Zhou court, having lost its homeland in the Guanzhong region, held nominal power, but had real control over only a small royal demesne centered on Luoyi. During the early part of the Zhou dynasty period, royal relatives and generals had been given control over fiefdoms in an effort to maintain Zhou authority over vast territory. As the power of the Zhou kings waned, these fiefdoms became increasingly independent states.
