History · The 20th century
1955–1975
Cold War proxy conflict in south-east Asia, and America's longest war to that date
The war fought between the communist North, backed by the Soviet Union and China, and the southern republic backed by the United States, after the French defeat at Dien Bien Phu in 1954 and the partition of the country at the 17th parallel. American involvement escalated from advisers to combat troops after the Gulf of Tonkin Resolution of 1964, peaking at more than half a million personnel in 1968. The Tet Offensive of that year, though a military setback for the communists, shattered American confidence; Nixon's policy of Vietnamisation withdrew troops, the Paris Peace Accords of January 1973 ended direct American involvement, and northern forces took Saigon on 30 April 1975.
