The War of Vietnam, it took place in Vietnam, Laos and Cambodia and lasted from April 30, 1975 to November 1st 1955, the War occured for 19 years 5 months 4 weeks and 1 day. The United States intervened and viewed their intervention as a way to prevent the communist take over of Southern Vietnam. The U.S. involvement was initially a mere back up to the French who were there already fighting the war, the involvement began spiking as the years bore on especially in 1961 then spiking even higher just a year later in 1962. It peaked in 1968 and from there dropped slowly as the American troops were withdrawn and 'peace' was given reign. Though there was the Paris Peace Accords signed and passed fighting still continued.
