Zhou ruled China longer than any other royal house
The Zhou dynasty lasted about 790 years, from roughly 1046 BC to 256 BC—the longest royal span in Chinese history. Western Zhou power later fractured into Spring and Autumn decentralisation and Warring States combat while bronzework peaked and Confucianism, Taoism, and Legalism took shape.
Myth traces the lineage to Jiang Yuan’s miraculous conception of Qi after stepping in Shangdi’s footprint. Historical Zhou kings such as Wu kept ceremonial Shang capitals while building Haojing; kinship feudalism thinned across generations until peripheral lords outgrew the centre. Northern Rong and Xianyun pressures climaxed near Western Zhou’s end.
Eastern Zhou after the 771 BC eastward move saw royal authority ebb through Spring and Autumn (c. 771–481 BC) into the Warring States free-for-all. Language studies suggest Zhou speech was close to Shang in vocabulary and syntax. Bronze ritual vessels from the era remain artistic high-water marks.
The clan's rise before the conquest is told in stages. Liu restored farming and settled his people at Bin; Tai moved them to Zhou in the Wei River valley, which remained their base after they beat the Shang. Tai passed over his elder sons Taibo and Zhongyong, said to have fled south and founded Wu, in favour of Jili, a warrior later killed by Shang forces. Western Zhou ended in 771 BC after King You demoted his queen for the commoner Bao Si: her father, the Marquis of Shen, joined the Quanrong, who sacked Haojing and killed You, and nobles crowned the marquis's grandson as King Ping and moved the capital east to Wangcheng.
The dynasty's most durable idea was the Mandate of Heaven, the claim that Heaven had ordered the Zhou to replace a corrupt Shang and would equally withdraw power from any ruler who let his people suffer. Because eclipses and disasters could cast doubt on that mandate, the court invested heavily in astronomy for its royal calendar. The line ended when Qin captured Wangcheng in 256 BC and King Nan died. Its later centuries also produced the Hundred Schools of Thought, as rival lords sponsored wandering scholars at places such as Qi's Jixia Academy.
