The Vietnam War
The Vietnam War (1955-1975) was a prolonged conflict between communist North Vietnam and South Vietnam, backed by the United States, that became one of the most controversial and consequential conflicts of the Cold War era.
The war grew out of Vietnam's struggle for independence from French colonial rule and split along Cold War lines, with the United States providing increasing military support to South Vietnam to prevent the spread of communism.
U.S. involvement escalated significantly in the mid-1960s, eventually involving over 500,000 American troops at its peak, and the war became deeply unpopular domestically amid mounting casualties and televised coverage of its brutality.
The war ended in 1975 with the fall of Saigon and the reunification of Vietnam under communist rule, leaving a lasting impact on American foreign policy and a profound and lasting toll on Vietnam itself.
