The reign of the seventh Nguyễn dynasty emperor lasted exactly seven months and twenty-nine days, beginning with an enthronement at five o'clock in the morning on 1 December 1883. Born as Nguyễn Phúc Ưng Đăng, the fifteen-year-old monarch assumed control during a volatile period of court instability in Huế, eventually dying in the Kiến Thành Palace during the summer of 1884.
Early Life and Adoption
Born in Huế on 12 February 1869, he was the son of Nguyễn Phúc Hồng Cai and Bùi Thị Thanh. As Emperor Tự Đức faced difficulties regarding heirs, he adopted several children, including this prince, his cousin Dục Đức, and his brother Đồng Khánh. This arrangement provided a pool of potential successors to the throne under the royal household's structure.

The power dynamics within the court shifted dramatically following the regicide of Emperor Hiệp Hoà. Regents Tôn Thất Thuyết and Nguyễn Văn Tường sought to stabilize the transition by installing the fifteen-year-old prince as the new sovereign. His formal installation took place on 1 December 1883, marking the start of a brief period of authority for the young ruler.
Premature Death
The emperor struggled with persistent health issues throughout his short tenure. He died in the Kiến Thành Palace on 31 July 1884. His passing occurred only months into his reign, leading to speculation regarding the cause of death. Rumors suggested he had been poisoned by his adoptive mother, the Noble Consort Học phi, and the regent Nguyễn Văn Tường, allegedly because he discovered their clandestine affair. His remains were interred at the Tomb of Kiến Phúc.
