越南国
During World War II, Imperial Japan attacked Indochina and wrested control from France, but when they were defeated by the Allies in 1945, a power vacuum resulted. The communist-dominated Vietminh of Ho Chi Minh fought for Vietnamese independence, while the French attempted to regain control of their colony by creating the French Union-allied State of Vietnam. Up until 1954, the First Indochina War raged. In 1954, the French lost the Battle of Dien Bien Phu and the Geneva Conference was held to determine the future of French Indochina. The Vietminh were given control of North Vietnam, while the State of Vietnam controlled the territory south of the 17th parallel. The Geneva agreements, which the State of Vietnam did not sign, called for reunification elections to be held in 1956. The State of Vietnam received support from the US and other anti-communist countries in the midst of the Cold War, which saw it as a partner in a fight against the spread of communism.
