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.
Gao Xianzhi
Gao Xianzhi, or Go Seonji, (died January 24, 756) was a Tang dynasty general of Korean descent. He was known as a great commander during his lifetime. He is most well known for taking part in multiple military expeditions to conquer the Western Regions, over the Pamir Mountains, and reaching the Aral Sea and the Caspian Sea. In 751 he commanded the Tang forces during the Battle of Talas, fighting against the Abbasid Caliphate. The Tang defeat is considered to mark the end of both Tang western expansion and Abbasid eastern expansion.
