Ostpolitik, West Germany's "Eastern Policy," marked a shift in Cold War diplomacy. Initiated by Chancellor Willy Brandt in the late 1960s, it aimed to normalize relations with Eastern European countries and the Soviet Union. This policy replaced confrontation with dialogue and cooperation. It led to key treaties, improved East-West relations, and laid groundwork for German reunification. Ostpolitik's legacy continues to influence German foreign policy today.
