Emperor Ai of Tang
Emperor Ai of Tang (27 October 89226 March 908), also known as Emperor Zhaoxuan (), born Li Zuo, later known as Li Chu (), was the last emperor of the Tang dynasty of China. He reigned—as but a puppet ruler—from 904 to 907. Emperor Ai was the son of Emperor Zhaozong.
Liu Rengong
Liu Rengong (劉仁恭) (died 914) was a warlord late in the Chinese dynasty Tang Dynasty who controlled Lulong Circuit (盧龍, headquartered in modern Beijing) from 895 (when his one-time lord Li Keyong conquered Lulong and left him in charge of it) to 907 (when he was overthrown by his son Liu Shouguang and put under house arrest). He was initially a Lulong officer, but later fled to Li Keyong's Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi). After Li conquered Lulong and left him in charge, he turned against Li and became an independent warlord, although at times he and Li would still act in concert. His domain later became the basis of the Five Dynasties and Ten Kingdoms period state Yan that Liu Shouguang established. In 913, however, Li Keyong's son and successor Li Cunxu the Prince of Jin conquered Yan and captured both Liu Shouguang and Liu Rengong; he put them to death the next year.
