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.
Huang Chao
Although Huang Chao was one of many rebel leaders in Chinese history, the impact of his rebellion can be compared to that of Taiping Rebellion or the Yellow Turbans. Huang Chao's rebellion greatly weakened Tang and it eventually led to the demise of the Tang dynasty in 907, by Huang Chao's former follower Zhu Wen, when he usurped the throne from Emperor Ai of Tang and initiating several decades of civil war called the Five Dynasties and Ten Kingdoms period.
