The Helsinki Accords, signed in 1975, were significant during the Cold War as they represented a diplomatic effort to improve relations between the East and West. The Accords contained provisions for human rights, economic cooperation, and territorial integrity, which provided a framework for dialogue. By recognizing existing borders and promoting human rights, they fostered a sense of accountability and expectation for reforms in Eastern Europe. The Accords laid the groundwork for the eventual collapse of the Iron Curtain and the dissolution of the Soviet Union in the late 20th century.
