The Vietnam War, (also known as the Second Indochina War, Vietnam Conflict, and in Vietnam as the American War), took place from 1955 to 1975. The war was fought between the Communist-supported Democratic Republic of Vietnam and the United States-supported Republic of Vietnam, beginning with the presence of a small number of US military advisors in 1955 and escalating into direct US involvement in a ground war in 1965. US combat forces were withdrawn in early 1973 pursuant to the Paris Peace Accords, but the war continued concluding with the Fall of Saigon on 30 April 1975.
