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.
Liu Wenjing
Liu Wenjing (568–619), courtesy name Zhaoren, formally the Duke of Lu, was a statesman and one-time Chancellor of the Tang dynasty. He initially served as an official of the Sui dynasty and was one of the driving forces in persuading the general Li Yuan to rebel against Emperor Yang of Sui. He assisted Li Yuan in establishing the Tang dynasty and becoming its first ruler. After Li Yuan became the emperor, he did not award the same honours to Liu Wenjing as he did to Pei Ji, thus Liu became very resentful. He engaged sorcerers to help him seek divine favours, but was executed after Li Yuan found out about it.
