Emperor Ai of Tang
Li Zuo was born in 892, at the main palace at the Tang imperial capital Chang'an. His father Emperor Zhaozong was already emperor at that point, and he was Emperor Zhaozong's ninth son. His mother was Consort He, who had previously given birth to an older brother of his, Li Yu, Prince of De, who was Emperor Zhaozong's oldest son.
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.
