Which agreement was signed to officially end the Vietnam War?

The Paris Peace Accords were the official agreement that aimed to bring an end to the Vietnam War. Signed on January 27, 1973, the accords sought to establish peace in Vietnam and included a ceasefire as well as the withdrawal of American forces from the region. They also called for the recognition of the sovereignty of North and South Vietnam and included provisions for the reunification of the country through peaceful means.

In contrast, the Geneva Accords, signed in 1954, primarily dealt with the division of Vietnam into North and South at the 17th parallel, setting the stage for future conflict but not formally ending the war. The Camp David Accords were a peace agreement between Egypt and Israel in 1978 and have no relation to the Vietnam War. The North Atlantic Treaty, established in 1949, created NATO and also does not pertain to the Vietnam conflict. Thus, the Paris Peace Accords stand as the definitive agreement that concluded U.S. involvement in Vietnam.
