Tang dynasty
Zhu Wen, originally a salt smuggler who had served under the rebel Huang Chao, surrendered to Tang forces. By helping to defeat Huang, he was granted a series of rapid military promotions. In 907 the Tang dynasty was ended when Zhu Wen, now a military governor, deposed the last emperor of Tang, Emperor Ai of Tang, and took the throne for himself (known posthumously as Emperor Taizu of Later Liang). He established the Later Liang, which inaugurated the Five Dynasties and Ten Kingdoms period. A year later Zhu Wen had the deposed Emperor Ai poisoned to death.
Li Yu (Southern Tang)
Li Yu (; 937 – 15 August 978), before 961 known as Li Congjia (李從嘉), also known as Li Houzhu (李後主; literally "Last Ruler Li" or "Last Lord Li"), was the third ruler of the Southern Tang state during imperial China's Five Dynasties and Ten Kingdoms period. He reigned from 961 until 976, when he was captured by the invading Song Dynasty armies which annexed his kingdom. He died by poison on orders of Emperor Taizong of Song after 2 years essentially as an exiled prisoner.
