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 Yanzheng
Wang Yanzheng (王延政) (died 951?), known as Tiande Emperor (天德帝) after his era name of Tiande, formally Prince Gongyi of Fu (福恭懿王), also known during Min as the Prince of Fusha (富沙王), was the last ruler of the Chinese Five Dynasties and Ten Kingdoms Period state Min. In 943, he, then in civil war with his brother Wang Yanxi (Emperor Jingzong), declared himself emperor of a new state of Yin at his base Jian Prefecture (建州, in modern Nanping, Fujian), but after Wang Yanxi was killed by the general Zhu Wenjin, who was himself assassinated thereafter, Wang Yanzheng reclaimed the title of Emperor of Min. His reign would last less than three years overall, though, as Min's northwestern neighbor Southern Tang bore down militarily on him and forced his surrender, ending Min.
