Emperor T? ?c (22 September 1829 - 17 July 1883) (full name: Nguy?n Ph鷆 H?ng Nh?m; also Nguyen Phuc Thi) was the fourth emperor of the Nguy?n Dynasty of Vietnam and reigned from 1847-1883.

The son of Emperor Thi?u Tr?; Prince Nguy?n Ph鷆 H?ng Nh?m succeeded his father with the reigning title of T? ?c; but family troubles caused his era to have a violent start. Thi?u Tr? had passed over his more moderate eldest son; H?ng B?o; to give the throne to T? ?c; known for his staunch Confucianism and opposition to foreigners and innovation. As a result; and due to the repressive policies of the previous Nguy?n Dynasty emperor; there was now a great deal of dissatisfaction with Nguy?n rule and a legitimate royal figure to rally this opposition.
