WORLD HISTORY

Detailed explanation-1: -On April 30, 1975, the last few Americans still in South Vietnam were airlifted out of the country as Saigon fell to communist forces.

Detailed explanation-2: -Opposition to the war in the United States bitterly divided Americans, even after President Richard Nixon ordered the withdrawal of U.S. forces in 1973. Communist forces ended the war by seizing control of South Vietnam in 1975, and the country was unified as the Socialist Republic of Vietnam the following year.

Detailed explanation-3: -On March 29, 1973 the last U.S. combat troops left South Vietnam, ending direct U.S. military involvement in the Vietnam War. Military advisers to the South Vietnamese Army remained, as did Marines protecting U.S. installations, and thousands of Defense Department civilians.

Detailed explanation-4: -The remaining Americans escaped in a series of frantic air-and sealifts with Vietnamese friends and coworkers. A military government was instituted, and on July 2, 1976, the country was officially united as the Socialist Republic of Vietnam with its capital in Hanoi. Saigon was renamed Ho Chi Minh City.

Detailed explanation-5: -In January 1973, the United States and North Vietnam concluded a final peace agreement, ending open hostilities between the two nations. War between North and South Vietnam continued, however, until April 30, 1975, when DRV forces captured Saigon, renaming it Ho Chi Minh City (Ho himself died in 1969).
