When did the Vietnam War start?

Answer 1

The Vietnam War began in 1955 and ended in 1975. The beginning is generally regarded as the declaration by Ngo Diem of the Republic of Vietnam in late October, 1955.

The US role began before the French defeat in 1954 that led to the "temporary" partition of French Indochina. Presidents Eisenhower and Kennedy sent military "advisers" and allowed the CIA to support South Vietnam against the communist North (supported by the USSR).

Direct use of US air and ground forces began in 1965, after the Gulf of Tonkin incident during the term of President Lyndon Johnson. After three years of war produced no better military situation, Richard Nixon was elected and began to promote a negotiated withdrawal ("peace with honor") that amounted to abandonment of the South Vietnamese and their conquest by the North.
