Which peace treaty was signed to establish peace in Vietnam and end the Vietnam War?

The Paris Peace Accords, officially titled the Agreement on Ending the War and Restoring Peace in Viet Nam, was a peace treaty signed on January 27, 1973, to establish peace in Vietnam and end the Vietnam War. The treaty included the governments of the Democratic Republic of Vietnam (North Vietnam), the Republic of Vietnam (South Vietnam), and the United States, as well as the Provisional Revolutionary Government (PRG) that represented indigenous South Vietnamese revolutionaries.

US ground forces up to that point had been sidelined with deteriorating morale and gradually withdrawn to coastal regions, not partaking in offensive operations or much direct combat for the preceding two-year period. The Paris Agreement Treaty would in effect remove all remaining US Forces, including air and naval forces in exchange for Hanoi's POWs. Direct U.S. military intervention was ended, and fighting between the three remaining powers temporarily stopped for less than a day. The agreement was not ratified by the United States Senate.
