1975 marked the end of the Vietnam War, sometimes called the Second Indochina War or the American War. The North Vietnamese People's Army of Vietnam (PAVN) launched the Spring Offensive in March; the South Vietnamese Army of the Republic of Vietnam (ARVN) was quickly defeated. The North Vietnamese captured Saigon on April 30, accepting the surrender of South Vietnam. In the final days of the war, the United States, which had supported South Vietnam for many years, carried out an emergency evacuation of its civilian and military personnel and more than 130,000 Vietnamese.
