The Most Important Meetings of the Allies During World War II The History of the Tehran Conference, Yalta Conference, and Potsdam Conference

*Includes pictures *Includes eyewitness accounts of the conferences *Includes online resources and a bibliography for further reading Separated by vast gulfs of political, cultural, and philosophical divergence, the three chief Allied nations of World War II - the United States, the Soviet Union, and Great Britain - attempted to formulate a joint policy through a series of three conferences during and immediately after the conflict. The first meeting took place in Tehran in late 1943, while the fate of World War II still hung in the balance. The fate of World War II hung in the balance in 1943. On the Eastern Front, the opposed juggernauts of the Wehrmacht, army of Adolf Hitler's Third Reich, and the Red Army, the military force of Josef Stalin's Soviet Union, grappled in a nearly apocalyptic battle. Black smoke rose into the steppe air from burning vehicles strewing the landscape, while millions of men maneuvered, fought, and died in a series of brutal encounters. Meanwhile, the Western Allies succeeded in ousting the Germans from North Africa, then took Sicily with Operation Husky and landed in Italy. There, the tough, hardened warriors of the German military turned the Italian peninsula into a vast fortress; these seasoned fighters made the determined Anglo-American forces pay a bitter price for each mountain ridge, river crossing, and stony valley swept by cunningly-placed gun emplacements. Adolf Hitler's Third Reich had scant time remaining when the "Big Three" met at the Yalta Conference in February 1945 to discuss the future of Germany, Europe, and the postwar world as a whole. No doubt existed regarding the war's outcome; the Americans had shattered the Wehrmacht's desperate last throw in the west, the Ardennes Offensive, during the Battle of the Bulge in the weeks immediately preceding Yalta, and the Soviet front lay just 50 miles east of Berlin, with the Red Army preparing for its final push into the Reich's capital after a successful surprise winter campaign. Among the agreements, the Conference called for Germany's unconditional surrender, the split of Berlin, and German demilitarization and reparations. Stalin, Churchill and Roosevelt also discussed the status of Poland, and Russian involvement in the United Nations. By this time Stalin had thoroughly established Soviet authority in most of Eastern Europe and made it clear that he had no intention of giving up lands his soldiers had fought and died for. The best he would offer Churchill and Roosevelt was the promise that he would allow free elections to be held. He made it clear, though, that the only acceptable outcome to any Polish election would be one that supported communism. Though it came so shortly after Yalta, the Potsdam Conference also highlighted a turnover of leadership on the world stage. British Prime Minister Winston Churchill, who gave his nation hope in the darkest days of World War II, had suffered a stunning defeat at the hands of the Labor candidate Clement Attlee, who replaced him towards the end of the Conference. President Franklin Delano Roosevelt died prior to the meeting, leading to his replacement by the new president Harry S. Truman, a keen-minded pragmatist whose intense focus on America's advantage contrasted with Roosevelt's internationalism. Only General Secretary Josef Stalin, dictator of the Soviet Union, remained unchanged from the earlier summit. World War II was so horrific that in its aftermath, the victorious Allies sought to address every aspect of it to both punish war criminals and attempt to ensure that there was never a conflict like it again. World War II was unprecedented in terms of the global scale of the fighting, the number of both civilian and military casualties, the practice of total war, and war crimes. World War II also left two undisputed, ideologically opposed superpowers standing, shaping global politics over the last 65 years.
