When was the Yalta Conference of the Allied Powers held represented by Stalin, Roosevelt and Churchill?

The Yalta Conference, also known as the Crimea Conference and codenamed Argonaut, held February 4–11, 1945, was the World War II meeting of the heads of government of the United States, the United Kingdom, and the Soviet Union to discuss the postwar reorganization of Germany and Europe. The three states were represented by President Franklin D. Roosevelt, Prime Minister Winston Churchill, and Premier Joseph Stalin, respectively. The conference was held near Yalta in Crimea, Soviet Union, within the Livadia, Yusupov, and Vorontsov Palaces.

The aim of the conference was to shape a postwar peace that represented not only a collective security order but also a plan to give self-determination to the liberated peoples of Europe. The meeting was intended mainly to discuss the re-establishment of the nations of war-torn Europe. However, within a few years, with the Cold War dividing the continent, the conference became a subject of intense controversy.
