On February fourth to eleventh, the Yalta Conference commenced. It was the second meeting during the war between U.S. President Franklin D. Roosevelt, British Prime Minister Winston Churchill, and Soviet Leader Joseph Stalin. During the conference, the three leaders agreed to demand Germany to surrender and began to plan a post-war world. Stalin agreed to have free governments in Eastern Europe and to enter the war against Japan. He was promised the return of land lost to Japan in the Russian-Japanese War. Most of these agreements were initially kept secret, but the agreements of the conference became controversial after Soviets and Americans went into the Cold War.
