The Indochina War refers to a series of conflicts in Southeast Asia, primarily involving Vietnam, Laos, and Cambodia. The first Indochina War (1946-1954) was fought between the French colonial forces and the Viet Minh, a communist-led nationalist movement. This war ended with the Geneva Accords, which temporarily divided Vietnam into North and South. The second Indochina War, commonly known as the Vietnam War (1955-1975), involved North Vietnam, supported by communist allies, and South Vietnam, backed by the United States and other anti-communist nations. This conflict resulted in significant loss of life and ultimately led to the reunification of Vietnam under communist control.
