The abdication of Emperor Bảo Đại (Vietnamese: Chiếu thoái vị của Hoàng Đế Bảo Đại) took place on 25 August 1945 and marked the end of the 143-year reign of the Nguyễn dynasty over Vietnam ending the Vietnamese monarchy. Bảo Đại abdicated in response to the August Revolution. A ceremony was held handing power over to the newly established Democratic Republic of Vietnam, which was established during the end of World War II in Asia as Vietnam had been occupied by French and later Japanese imperialists.
