Western Zhou

The Western Zhou (; – 771 BC) was a period of Chinese history, approximately first half of the Zhou dynasty, before the period of the Eastern Zhou. It began when King Wu of Zhou overthrew the Shang dynasty at the Battle of Muye and ended when Quanrong pastoralists sacked its capital Haojing and killed King You of Zhou in The Western Zhou early state was ascendant for about seventy-five years and then slowly lost power. The former Shang lands were divided into hereditary fiefs which became increasingly independent of the king. In 771 BC, the Zhou court was driven out of the Wei River valley; afterwards real power was in the hands of the king's nominal vassals. "Western" describes the geographical situation of the Zhou royal capitals, clustered near present-day Xi'an. Civil war Few records survive from this early period and accounts from the Western Zhou period cover little beyond a list of kings with uncertain dates. King Wu died two or three years after the conquest. Because his son, King Cheng of Zhou was young, his brother, the Duke of Zhou Ji Dan assisted the young and inexperienced king as regent. Wu's other brothers (Shu Du of Cai, Guan Shu, and Huo Shu), concerned about the Duke of Zhou's growing power, formed an alliance with Wu Geng and other regional rulers and Shang remnants in the rebellion of the Three Guards. The Duke of Zhou stamped out this rebellion and conquered more territory to bring other people under Zhou rule.
