In 1941, the Việt Minh, a nationalist liberation movement based on a Communist Ideology, emerged under the Vietnamese revolutionary leader Hồ Chí Minh. The Việt Minh sought independence for Vietnam from France and the end of the Japanese occupation. Following the military defeat of Japan and the fall of its puppet Empire of Vietnam in August 1945, anarchy, rioting, and murder were widespread, as Saigon's administrative services had collapsed. The Việt Minh occupied Hanoi and proclaimed a provisional government, which asserted national independence on 2 September.
