Emperor Ai of Tang
In 904, Zhu forced Emperor Zhaozong to move the capital from Chang'an to Luoyang, which was even more firmly under his control. Later that year, fearing that the adult Emperor Zhaozong would try to rise against him while he was away on campaigns against other warlords, he had Emperor Zhaozong assassinated. Bypassing Li Yu and the other older princes, he had an edict issued in Emperor Zhaozong's name creating Li Zuo crown prince and changing his name to Li Chu. Shortly after, Li Chu took the throne (as Emperor Ai). Empress He, who survived the assassination, was honored empress dowager.
Chinese emperors family tree (middle)
The following is a simplified family tree for the Tang dynasty (唐朝), which ruled China between AD 618 and 907. The Tang dynasty was interrupted by the reign of Empress Wu Zetian (AD 690–705), who after deposing her sons, declared herself the founder of a second Zhou (周) dynasty; the Tang dynasty was resumed by her sons following her abdication. The dynasty was named for the family title: the Li (李) family were the Dukes of Tang.
