Wanyan Yongji
Wanyan Yongji (died 11 September 1213), childhood name Xingsheng, was the seventh emperor of the Jurchen-led Jin dynasty of China.During Wanyan Yongji's reign, the Mongols, under the leadership of Genghis Khan, had been planning to attack the Jin dynasty.Yelü Liuge submitted to the Mongols and led the rebels to defeat a 600,000-strong Jin army in Dijinao'er (迪吉腦兒; near present-day Changtu County, Liaoning Province).In the eighth month of 1213, when the Mongols attacked Zhongdu again, the general Heshilie Zhizhong (紇石烈執中; also known as Hushahu 胡沙虎) rebelled against Wanyan Yongji and assassinated him.He also gathered about 300 officials to support him and openly urged Emperor Xuanzong to posthumously demote Wanyan Yongji to the status of a commoner.
