The Battle of Yangcheng was fought between the warlords Yuan Shao and Yuan Shu as the coalition against Dong Zhuo fell apart in 191 in the late Eastern Han dynasty. Sun Jian, Yuan Shu's nominal subordinate returning from his triumphant capture of the abandoned capital of Luoyang, became involved in Yuan Shao's and Yuan Shu's personal feud as the former allies turned against one another. Yuan Shao's forces, under Zhou Yu, first got the upper hand against Sun Jian's forces, but were beaten back by Sun's counterattack.
