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.
Trần Thiếu Đế
Trần Thiếu Đế (, 1396 - 1400), was the twelfth and the last emperor of the Trần dynasty who reigned over Vietnam from 1398 to 1400.
Trần Thiếu Đế's name (𤇼 / Yên) was suggested by "Khâm định Việt sử thông giám cương mục", because Nguyễn dynasty's officials could not find the exact Chinese character for this sovereign (). At the age of only three, he was chosen to succeed his father Trần Thuận Tông who was forced by Hồ Quý Ly to resign and hold the title Retired Emperor. Only two years after Thiếu Đế's coronation, Hồ Quý Ly overthrew the Emperor to establish his own dynasty, the Hồ Dynasty.
Thiếu Đế ("Young Emperor") was born in 1396 as Trần Yên (陳), first child of the Emperor Trần Thuận Tông, and his wife, the Queen Thánh Ngâu who was daughter of Hồ Quý Ly. On March 15 of the Lunar calendar, 1398, under pressure of Hồ Quý Ly, Thuận Tông had to cede the throne to his three-year-old son, now Trần Thiếu Đế, and held the position of retired emperor.
