The Potsdam Conference, held in July-August 1945, was significant as it marked a crucial moment in post-World War II diplomacy, attended by the leaders of the United States, the United Kingdom, and the Soviet Union. The conference aimed to address the administration of defeated Nazi Germany, set post-war order, and discuss the implications of the atomic bomb. Decisions made at Potsdam paved the way for the division of Germany into East and West, solidified the geopolitical landscape of post-war Europe, and contributed to rising tensions between the Soviet Union and the Western powers, ultimately leading to the Cold War.
