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.
Li Yu (Southern Tang)
Li Yu (; 937 – 15 August 978), before 961 known as Li Congjia (李從嘉), also known as Li Houzhu (李後主; literally "Last Ruler Li" or "Last Lord Li"), was the third ruler of the Southern Tang state during imperial China's Five Dynasties and Ten Kingdoms period. He reigned from 961 until 976, when he was captured by the invading Song Dynasty armies which annexed his kingdom. He died by poison on orders of Emperor Taizong of Song after 2 years essentially as an exiled prisoner.
