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.
Administrative divisions of the Tang dynasty
With the extermination of the court eunuchs in 903, the warlord Zhu Wen obtained absolute authority over the emperor. Since Zhu's core holdings were in Henan, he forced Zhaozong to move east to Luoyang in 904, where he was killed. The great city of Chang'an was abandoned and its structures dismantled for their building materials, never again attaining the strategic importance and prestige it presided over for the last millennium. Three years later in 907, the Tang empire officially came to a close when Zhu Wen dethroned its last sovereign.
