The Paris Peace Accords, officially the Agreement on Ending the War and Restoring Peace in Viet Nam, was signed in 1973 to establish peace in Vietnam and end the Vietnam War. The agreement was signed by Vietnamese on both sides and American diplomats. The negotiations began in 1968 and finished after various lengthy delays. The peace was broken by the 1975 Spring Offensive by North Vietnam that capitulated South Vietnam and reunited the country under communism.
The Paris Peace Accords marked the final withdrawal of the United States in Vietnam and humiliated the American military. It displayed the shortcomings of American military strategy and the success of communist guerrillas. In addition, it demonstrated the errors of the Domino Theory as communism failed to spread further than Cambodia and Laos despite the communist takeover of Vietnam
