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.
History of Asia
The Tang dynasty began to decline under the rule of Emperor Xuanzong, who began to neglect the economy and military and caused unrest amongst the court officials due to the excessive influence of his concubine, Yang Guifei, and her family. This eventually sparked a revolt in 755. Although the revolt failed, subduing it required involvement with the unruly nomadic tribes outside of China and distributing more power to local leaders—leaving the government and economy in a degraded state. The Tang dynasty officially ended in 907 and various factions led by the aforementioned nomadic tribes and local leaders would fight for control of China in the Five Dynasties and Ten Kingdoms period.
