In 1946, the states of French Indochina withdrew from the French Union, leading to the Indochina War (1946–54). Ho Chi Minh, who had been a co-founder of the French Communist Party in 1920 and had founded the Vietminh in 1941, declared independence from France, and led the armed resistance against France's reoccupation of Indochina. Cambodia and Laos became independent in 1953, and the 1954 Geneva Accords ended France's occupation of Indochina, leaving North Vietnam and South Vietnam independent.
