Emperor Ai of Tang
Emperor Ai of Tang (27 October 89226 March 908), also known as Emperor Zhaoxuan (), born Li Zuo, later known as Li Chu (), was the last emperor of the Tang dynasty of China. He reigned—as but a puppet ruler—from 904 to 907. Emperor Ai was the son of Emperor Zhaozong.
Emperor Xuanzong of Tang (9th century)
Emperor Xuānzong of Tang (July 27, 810 – September 7, 859) (reigned April 25, 846 – September 7, 859) was an emperor in the latter part of the Tang dynasty of China. Personally named Li Yi, later renamed Li Chen (), and known before his reign as the Prince of Guang, he was considered the last capable emperor of Tang China. Succeeding emperors after Xuānzong would either be too young or be dominated by eunuchs or warlords. Emperor Xuānzong was the 13th son of Emperor Xianzong (r. 806–820) and an uncle of the previous three emperors, Emperor Jingzong, Emperor Wenzong, and Emperor Wuzong.
