When did the Vietnam War end?
Answer
In 1975
Explanation
The Vietnam War ended in 1975 when North Vietnamese forces overran the South Vietnamese capital of Saigon on April 30, 1975, completing the communist takeover of the south. The path to that ending began with the Paris Peace Accords, signed on January 27, 1973 by representatives of the United States, South Vietnam, North Vietnam, and the Viet Cong's Provisional Revolutionary Government. The accords required all American combat troops to withdraw within 60 days and called for a cease-fire and the release of prisoners of war. The last American ground combat units left Vietnam by March 29, 1973, and 591 American POWs were released that spring in Operation Homecoming.
The Paris Accords did not end the fighting between North and South Vietnam, however. North Vietnamese forces remained in the south, and the war continued at lower intensity for two more years. Watergate weakened President Richard Nixon, who resigned on August 9, 1974, and Congress slashed military aid to South Vietnam from 2.3 billion dollars in fiscal 1973 to 700 million in fiscal 1975. North Vietnam, supplied by the Soviet Union and China, began a major offensive in March 1975 that overwhelmed the South Vietnamese army within weeks.
Cities fell rapidly. Hue was lost on March 25, Da Nang on March 30, and Nha Trang on April 1. President Gerald Ford called the war finished from the American perspective in a speech on April 23, 1975. Operation Frequent Wind, launched on April 29, 1975, was the largest helicopter evacuation in history, lifting more than 7,000 Americans and South Vietnamese from the United States Embassy in Saigon and other points. Iconic photographs showed helicopters landing on rooftops and being pushed off ships into the sea to make room for more arrivals.
The next morning, April 30, 1975, North Vietnamese tanks crashed through the gates of Independence Palace in Saigon. President Duong Van Minh, who had taken office two days before, surrendered unconditionally. Saigon was renamed Ho Chi Minh City. North and South Vietnam were formally reunified on July 2, 1976 as the Socialist Republic of Vietnam. The war was over at a cost of about 58,000 American dead, more than 250,000 South Vietnamese soldiers, more than a million communist combatants, and roughly 2 million Vietnamese civilians.
Why this matters for your test
USCIS asks when the Vietnam War ended to confirm applicants know the chronological closure of the longest American war up to that point. The 1975 collapse also explains the wave of Vietnamese refugees who became American citizens in the years that followed.
