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.
Wang Xingyu
Wang Xingyu (王行瑜) (d. 895) was a warlord late in the Chinese dynasty Tang Dynasty who controlled Jingnan Circuit (靜難, headquartered in modern Xianyang, Shaanxi) from 887 to his death in 895. At his prime, he and his ally Li Maozhen the military governor of Fengxiang Circuit (鳳翔, headquartered in modern Baoji, Shaanxi) had a stranglehold on the court of then-reigning Emperor Zhaozong, and were able to put two former chancellors that they disliked—Li Xi and Wei Zhaodu—to death over Emperor Zhaozong's objections. However, Li Keyong the military governor of Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi) then attacked them and defeated Wang. Wang fled and was killed in flight by his own subordinates.
