Towards the end of the 2nd millennium BC, the Shang were overrun by the Zhou dynasty from the Wei River valley to the west. The Zhou rulers at this time invoked the concept of the Mandate of Heaven to legitimize their rule, a concept that would be influential for almost every successive dynasty. The Zhou initially established their capital in the west near modern Xi'an, near the Yellow River, but they would preside over a series of expansions into the Yangtze River valley. Zhou administration was decentralised, with local elites responsible for collecting tribute and providing military support to the Zhou rulers.
