The Japanese promised not to interfere with the court at Huế, but in 1945, after ousting the French, coerced Bảo Đại into declaring Vietnamese independence from France as a member of Japan's "Greater East Asia Co-Prosperity Sphere"; the country then became the Empire of Vietnam. The Japanese had a Vietnamese pretender, Prince Cường Để, waiting to take power in case the new emperor's "elimination" was required. Japan surrendered to the Allies in August 1945, and the Viet Minh (under the leadership of communist Hồ Chí Minh) aimed to take power in a free Vietnam. Due to his popular political stand against the French and the 1945 famine, Hồ was able to persuade Bảo Đại to abdicate on 25 August 1945, handing power over to the Việt Minh – an event which greatly enhanced Hồ's legitimacy in the eyes of the Vietnamese people. Bảo Đại was appointed the "supreme advisor" to Hồ's Democratic Republic of Vietnam (DRV) in Hanoi, which asserted its independence on 2 September 1945. The DRV was then ousted by the newly formed French Fourth Republic in November 1946.
