The Yalta and Potsdam Conferences held in 1945 were designed to establish a set of agreements between the United States, the United Kingdom, and the Soviet Union (the Big Three) regarding the nature of a post war world. The main concern of these nations was how Germany and its people be assisted in their distress. This included human relief assistance, the dismemberment of Germany, reparations from Germany, and that free elections be held in Germany all in a peaceful manner. In addition, the construction of Poland's borders should be included as a 'main concern' of the Big Three. It was essential for the rebuilding of the economic and political life of those liberated that the reminents of Nazi occupation be dissolved.
