Emperor Ai of Tang
Emperor Ai of Tang (27 October 89226 March 908), also known as Emperor Zhaoxuan (), born Li Zuo, later known as Li Chu (), was the last emperor of the Tang dynasty of China. He reigned—as but a puppet ruler—from 904 to 907. Emperor Ai was the son of Emperor Zhaozong.
Zhu Youwen
In 907, Zhu Quanzhong had Tang Dynasty's last emperor, Emperor Ai, yield the throne to him, ending Tang and starting a new Later Liang as its Emperor Taizu. He created his sons imperial princes, and Zhu Youwen, who had become the deputy military governor of Xuanwu before he took the throne, was given the title of Prince of Bo. Emperor Taizu also made Zhu Youwen the mayor of Kaifeng (i.e., the old Xuanwu headquarters), as well as the director of Jianchang Hall (建昌院) — a conversion of the office overseeing financial matters for the four circuits into an imperial institution. After Emperor Taizu formally made Luoyang his capital in 903, he also made Kaifeng the eastern capital and Zhu Youwen its defender. It was said that, after this point, Zhu Youwen often spent time in drinking and was not as attentive to his responsibilities as before.
