The Yalta Conference was the meeting in February of 1945, the last year of World War II, between President Franklin Roosevelt, Soviet Premier Joseph Stalin and British Prime Minister Winston Churchill (the big three) at Yalta on the Crimean Peninsula in the USSR.
The main agreement of the conference regarded the decision for an unconditional surrender of the Nazis. They agreed to divide Germany into four occupation zones, with Berlin itself further divided into zones. They also agreed that free elections would be held in Soviet controlled Eastern Europe, but Stalin never had any intention of fulfilling this promise. The USSR also agreed to take part in the war against Japan, though they played a negligible role.
