The 1945 Meeting Site was the Yalta Conference in February 1945 and the Potsdam Conference in July 1945. The Yalta Conference was held in the Crimea, then part of the Soviet Union, and was attended by the leaders of the United States, the United Kingdom, and the Soviet Union. The Potsdam Conference was held in Germany and was attended by the same three leaders. Both conferences were important in determining the post-World War II world order.
