The key outcome of the Yalta Conference, held in February 1945 during World War II, was the agreement on the post-war reorganization of Europe. The meeting brought together leaders Franklin D. Roosevelt, Winston Churchill, and Joseph Stalin to discuss plans for defeating Nazi Germany and establishing a framework for peace. They addressed issues like the division of Germany, the formation of the United Nations, and the future of Eastern Europe. The conference set the tone for post-war relations and influenced the geopolitical landscape that emerged during the Cold War.
