The Vietnam War, also known as the Second Indochina War.
September 26, 1959[1] to April 30, 1975
The United States entered the war to prevent a communist takeover of South Vietnam as part of their wider strategy of containment.
The war exacted a huge human cost in terms of fatalities including 3 to 4 million Vietnamese from both sides, 1.5 to 2 million Laotians and Cambodians, and 58,159 U.S. soldiers.[15] By this war's end, the Vietnamese had been fighting foreign involvement or occupation in various wars for over a hundred years.
