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.
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.
