Ai, emperor of the Tang Dynasty (born 892)

Emperor Ai of Tang, also known as Emperor Zhaoxuan of Tang (唐昭宣帝), born Li Zuo, later known as Li Chu, was the last emperor of the Tang dynasty of China. He reigned—as a puppet ruler—from 904 to 907. Emperor Ai was the son of Emperor Zhaozong. He was murdered by Zhu Wen.

The Tang dynasty, or the Tang Empire, was an imperial dynasty of China that ruled from 618 to 907, with an interregnum between 690 and 705. It was preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period. Historians generally regard the Tang as a high point in Chinese civilisation, and a golden age of cosmopolitan culture. Tang territory, acquired through the military campaigns of its early rulers, rivalled that of the Han dynasty.
