The Paris Peace Accords were a set of agreements signed on January 27, 1973, that ended direct U.S. involvement in the Vietnam War and established a ceasefire between North and South Vietnam. The accords were signed by the United States, North Vietnam, South Vietnam, and the Viet Cong, and were brokered by the International Commission for Control and Supervision (ICCS).

The main provisions of the Paris Peace Accords included:

1. A ceasefire and the end of hostilities between the North and South Vietnamese forces.

2. The release of American prisoners of war and the removal of American troops from South Vietnam.

3. The establishment of a Four-Party Joint Military Commission to oversee the implementation of the ceasefire and resolve any disputes that arose.

4. The continuation of the existing South Vietnamese government and the recognition of the right of the South Vietnamese people to self-determination.

5. The agreement that both North and South Vietnam would respect the 17th parallel as a demarcation line and refrain from using force to reunify the country.

The Paris Peace Accords did not bring a lasting peace to Vietnam, as the fighting resumed within two years of the signing of the accords. Nevertheless, the accords did mark the end of direct U.S. involvement in the conflict, and the removal of American troops from Vietnam was a significant milestone in the history of the war. The Paris Peace Accords remain a significant and complex chapter in the history of the Vietnam War and its legacy continues to shape the region and the world today.
