Zhang Xianzhong
Zhang Xianzhong (张献忠 or Chang Hsien-chung; 18 September 1606 – 2 January 1647), nickname Huanghu (literally 'Yellow Tiger'), was a leader of a peasant revolt from Yan'an wei, Shaanxi (today Yulin, Shaanxi province). He conquered Sichuan in 1644, and named himself king and later emperor of the Xi dynasty (西朝 or Great Xi 大西). His rule in Sichuan was brief, and he was killed by the invading Qing army. He is commonly associated with the massacres in Sichuan that depopulated the region. However, the extent of his killings is disputed.
