The event that marked the formal end of the Vietnam War was the Fall of Saigon on April 30, 1975. This event occurred when North Vietnamese forces captured the capital of South Vietnam, effectively signaling the collapse of the South Vietnamese government. The Fall of Saigon led to the reunification of Vietnam under communist control. The war had significant ramifications for both Vietnam and the United States, resulting in widespread devastation, loss of life, and political upheaval. The U.S. officially concluded its involvement in Vietnam with the Paris Peace Accords in 1973, although intense conflict persisted until this final event.
