Yi Zong, Chinese emperor (b. 833)
Emperor Yizong of Tang (December 28, 833 – August 15, 873), né Li Wen, later changed to Li Cui (Chinese: 李漼), was an emperor of the Tang dynasty of China. He reigned from 859 to 873. Yizong was the eldest son of Emperor Xuanzong. After Emperor Xuanzong's death in 859, Emperor Yizong was placed on the throne by the eunuch Wang Zongshi (王宗實), who killed other eunuchs supporting another son of Emperor Xuanzong, Li Zi the Prince of Kui.

According to traditional historians, Emperor Yizong did not pay much attention to governmental affairs but instead chose to live in opulence, became an alcoholic and surrounded himself with women while his government levied heavy taxes on its citizens. A deeply devout Buddhist, even more so than his father, he would hold grand Buddhist ceremonies throughout the year as well as ordering frequent musical performances in the palace. If the entertainment was to his liking, Yizong would not only reward the entertainers greatly but also bestow governmental ranks. Emperor Yizong eventually exhausted the empire's treasury that had accumulated during his father's administration. Extreme hardships, including famines that forced people to resort to cannibalism, led to widespread agrarian rebellions late in his reign. Those rebellions would plague the reign of his son Emperor Xizong and doom Tang.
