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.
Zhu Tao
Zhu Tao (朱滔) (died 785), formally the Prince of Tongyi (通義王), was a general of the Chinese dynasty Tang Dynasty who initially served imperial causes during the reigns of Emperor Daizong and Emperor Dezong, but later turned against imperial rule in alliance with Wang Wujun, Tian Yue, and Li Na. Eventually, when his brother Zhu Ci rebelled at the Tang capital Chang'an and claimed imperial title, Zhu Tao became his crown prince, but after Zhu Ci was defeated and killed in 784, Zhu Tao submitted to Emperor Dezong again.
