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.
Yang Shihou
In 907, Zhu Quanzhong had Tang's last emperor, Emperor Ai, yield the throne to him, ending Tang and starting a new Later Liang as its Emperor Taizu. In 909, Emperor Taizu recalled Yang Shihou from Shannan East, commissioning him as the commander of the forces preparing to attack Lu Prefecture (潞州, in modern Changzhi, Shanxi), which was then ruled by Later Liang's archrival Jin (i.e., the state ruled by Li Keyong's son and successor Li Cunxu). He sent Wang Ban (王班) to Shannan East to serve as acting military governor in Yang's absence. (As Yang departed Xiang Prefecture, he warned Wang Ban that certain officers, including one Wang Qiu (王求), were unruly and might mutiny in his absence; Wang Ban took no precautions, however, and later in the year Wang Qiu assassinated Wang Ban and rebelled, but the rebellion was quickly put down.)
