  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. After the military defeat of Japan in World War II and the fall of its puppet government Empire of Vietnam in August 1945, Saigon's administrative services collapsed and chaos, riots, and murder were widespread. The Việt Minh occupied Hanoi and proclaimed a provisional government, which asserted national independence on 2 September.
  
  In July 1945, the Allies had decided to divide Indochina at the 16th parallel to allow Chiang Kai-shek of the Republic of China to receive the Japanese surrender in the north while Britain's Lord Louis Mountbatten received their surrender in the south. The Allies agreed that Indochina still belonged to France.
  
  But as the French were weakened by the German occupation, British-Indian forces and the remaining Japanese Southern Expeditionary Army Group were used to maintain order and help France reestablish control through the 1945–1946 War in Vietnam. Hồ initially chose to take a moderate stance to avoid military conflict with France, asking the French to withdraw their colonial administrators and for French professors and engineers to help build a modern independent Vietnam. But the Provisional Government of the French Republic did not act on these requests, including the idea of independence, and dispatched the French Far East Expeditionary Corps to restore colonial rule. This resulted in the Việt Minh launching a guerrilla campaign against the French in late 1946. The resulting First Indochina War lasted until July 1954. The defeat of French colonialists and Vietnamese loyalists in the 1954 battle of Điện Biên Phủ allowed Hồ to negotiate a ceasefire from a favourable position at the subsequent Geneva Conference.
  
  The colonial administration was thereby ended and French Indochina was dissolved under the Geneva Accords of 21 July 1954 into three countries—Vietnam, and the kingdoms of Cambodia and Laos. Vietnam was further divided into North and South administrative regions at the Demilitarised Zone, roughly along the 17th parallel north (pending elections scheduled for July 1956). A 300-day period of free movement was permitted, during which almost a million northerners, mainly Catholics, moved south, fearing persecution by the communists. This migration was in large part aided by the United States military through Operation Passage to Freedom. The partition of Vietnam by the Geneva Accords was not intended to be permanent, and stipulated that Vietnam would be reunited after the elections. But in 1955, the southern State of Vietnam's prime minister, Ngô Đình Diệm, toppled Bảo Đại in a fraudulent referendum organised by his brother Ngô Đình Nhu, and proclaimed himself president of the Republic of Vietnam. This effectively replaced the internationally recognised State of Vietnam by the Republic of Vietnam in the south—supported by the United States, France, Laos, Republic of China and Thailand—and Hồ's Democratic Republic of Vietnam in the north, supported by the Soviet Union, Sweden, Khmer Rouge, and the People's Republic of China.
