House of Nguyễn Phúc

The House of Nguyễn Phúc, also known as the House of Nguyễn Phước, is a family and a branch of the surname Nguyễn in Vietnam. Its members were the Nguyễn lords (1558–1777, 1780–1802) and emperors of the Nguyễn dynasty (1802–45). Its Bảo Đại was also emperor of the State of Vietnam (1949–55) and Domain of the Crown (1950–55). Nguyễn Bặc (924–79), an official of the Đinh dynasty, was its founder.

Under Emperor Gia Long, the family's rule was not only restored, but extended to the whole of Vietnam in 1802, thus marking the start of the unified Nguyễn dynasty. The Nguyễn dynasty agreed to French supervision in 1883. In 1887, Vietnam became part of the Indochinese Union, which was administered by a French governor general.

Emperor Bảo Đại, the last ruler of the dynasty, changed the name of the country from Annam back to Vietnam, a name that originated with Gia Long. He abdicated in fear for his life in 1945 after the Viet Minh attempted to assassinate one of his former prime ministers. The French returned following the surrender of Japan. Bảo Đại fled to Hong Kong, where he developed a reputation as a playboy.

French President Charles de Gaulle suggested that former Emperor Duy Tân return to Vietnam and reenter politics. Duy Tân, now a national hero, died when his return flight crashed in 1945. In 1949, Vietnamese non-communist nationalists and the French re-installed Bảo Đại and created the State of Vietnam with him as chief of state (國長 Quốc trưởng). The French also oversaw the creation of the Domain of the Crown where he was still officially considered to be the emperor. This territory existed until 1955. Bảo Đại died in 1997 in Paris, France.

According to a article by The New York Times in 1973, it was estimated then by former empress dowager Hoàng Thị Cúc mother of the last ruler Bảo Đại, that the royal family had over 200,000 descendants.
