Yalta Conference: The Meeting of the Big Three
In February 1945, the Yalta Conference marked a critical moment toward the end of World War II, where President Franklin Delano Roosevelt of the United States, British Prime Minister Winston Churchill, and Soviet Premier Joseph Stalin met. This conference held in Yalta, a resort city in the Soviet Crimea, involved extensive discussions about postwar reconstruction, the fate of Germany, Eastern Europe, and laying the groundwork for the United Nations. Key decisions at the Yalta Conference included the unconditional surrender of Germany, the division of Germany into four occupation zones with each zone controlled by one of the major Allied Powers (Great Britain, the Soviet Union, the United States, and France), Stalin's commitment to permit free elections in Eastern Europe (a promise that was later reneged upon), and the Soviet Union's agreement to join the fight against Japan in the Pacific in return for territorial concessions lost in the Russo-Japanese War of 1904-1905. Moreover, the discussion emphasized the importance of creating a new framework for international peace and security, which led to the formulation of the United Nations.
