Kiến Phúc
Vietnamese emperor (1869–1884)

Kiến Phúc (Hanoi: [kiən˧˦ fʊwk͡p̚˧˦], 12 February 1869 – 31 July 1884) was a child emperor of Vietnam, who reigned for less than 8 months, 1883–1884, as the 7th emperor of the Nguyễn dynasty.
Biography
Born in 1869, also known as Nguyễn Phúc Ưng Đăng, he was the nephew-turned-adopted son of Emperor Tự Đức. He reigned for 7 months and 29 days (2 December 1883 – 31 July 1884).
Along with his cousin Dục Đức and brother Đồng Khánh, he had been taken in by Tự Đức who was unable to have children of his own. After the regicide of Emperor Hiệp Hoà, the court regents Tôn Thất Thuyết and Nguyễn Văn Tường acted quickly to install the fifteen-year-old prince as the new Emperor. Kiến Phúc was quickly enthroned on 1 December 1883 at five o'clock in the morning.
Emperor Kiến Phúc was often hampered by poor health and died in Kiến Thành Palace on July 31, 1884 – less than 8 months after ascending the throne. His sudden death sparked rumors that the Emperor was poisoned by his adoptive mother, Tự Đức's Noble Consort Học phi and regent Nguyễn Văn Tường for he knew of their secret affair.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
