Emperor Ai of Tang
Li Zuo was born in 892, at the main palace at the Tang imperial capital Chang'an. His father Emperor Zhaozong was already emperor at that point, and he was Emperor Zhaozong's ninth son. His mother was Consort He, who had previously given birth to an older brother of his, Li Yu, Prince of De, who was Emperor Zhaozong's oldest son.
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.
