Emperor Xuānzong of Tang

Emperor Xuanzong of Tang 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 Xuanzong would either be too young or be dominated by eunuchs or warlords. Emperor Xuanzong was the 13th son of Emperor Xianzong and an uncle of the previous three emperors, Emperor Jingzong, Emperor Wenzong, and Emperor Wuzong.
