Russia / Soviet Union: Yalta Conference in February 1945 with (from left to right) Winston Churchill, Franklin D. Roosevelt and Joseph Stalin

The Yalta Conference, sometimes called the Crimea Conference and codenamed the Argonaut Conference, held February 4Ð11, 1945, was the World War II meeting of the heads of government of the United States, the United Kingdom and the Soviet Union, represented by President Franklin D. Roosevelt, Prime Minister Winston Churchill and Premier Joseph Stalin, respectively, for the purpose of discussing Europe's post-war reorganization. The conference convened in the Livadia Palace near Yalta in Crimea. The meeting was intended mainly to discuss the re-establishment of the nations of war-torn Europe. Within a few years, with the Cold War dividing the continent, Yalta became a subject of intense controversy. To some extent, it has remained controversial. Also present are Soviet Foreign Minister Vyacheslav Molotov (far left); Field Marshal Sir Alan Brooke, Admiral of the Fleet Sir Andrew Cunningham, RN, Marshal of the RAF Sir Charles Portal, RAF, (standing behind Churchill); General George C. Marshall, Chief of Staff of the United States Army, and Fleet Admiral William D. Leahy, USN, (standing behind Roosevelt). (Photo by: Pictures From History/Universal Images Group via Getty Images)
