Nguyễn Phúc Bảo Định was a Vietnamese prince born in 1920, known for being a member of the Nguyễn dynasty, the last ruling dynasty of Vietnam. He was the son of Emperor Bảo Đại, the last emperor of Vietnam, and played a role in the country's history during a time of significant political change. After the abdication of his father in 1945, Nguyễn Phúc Bảo Định lived in exile for many years. He returned to Vietnam after the war, but his life was largely overshadowed by the events of the Vietnam War and the subsequent reunification of the country in 1975.
