The conference that formally established the boundaries of post-World War II Europe in 1945 was the Yalta Conference. Held in February, it involved key Allied leaders: Franklin D. Roosevelt, Winston Churchill, and Joseph Stalin. The discussions focused on the reorganization of post-war Europe, the fate of Germany, and the administration of Eastern Europe. Key agreements included the division of Germany into occupation zones and plans for the United Nations. However, decisions made at Yalta also sowed the seeds of Cold War tensions, as differing visions for Europe’s future emerged between the United States and the Soviet Union.
