The Polish Cause in the Policies of the Big Three
what questions pertaining to the Polish cause were raised during the conferences of the Big Three;
how did the world powers shape Poland’s postwar borders;
what were the political agreements pertaining to Poland reached at the conferences of the Big Three;
why was the Provisional Government of National Unity acknowledged as the legal Polish government.
From the beginning, the Polish cause was a problematic question in the policies of the world powers, which manifested in, among others, their passivity in September 1939, despite the agreements between Poland and other states remaining in force. After Germany attacked the Soviet Union, the situation became even more complicated – suddenly, one of the aggressors came into the anti‑Hitler camp. This caused the Government‑in‑Exile’s expectations of preserving the pre‑war Eastern border of Poland and her diplomatic position to go unfulfilled.
Poland’s postwar future was decided during the three conferences of the Big ThreeBig Three that took place in Tehran (1943), Yalta, and Potsdam (1945). The leaders of the three powers – the United States, Great Britain, and the Soviet Union – established the new Polish borders between the Oder and the Curzon LineCurzon Line (Tehran and Yalta), agreed for Poland to join the Soviet sphere of influence, and agreed that a coalition government would be appointed, with the preparation of free, unrestrained parliamentary elections as its task (Yalta, Potsdam).
Those decisions were confirmed in Potsdam, where the Big Three accepted the Communist‑controlled Provisional Government of National UnityProvisional Government of National Unity, created in June 1945. The shape of the Oder‑Neisse border was determined as well, leaving the post‑German territories under the Polish administration (Silesia, Pomerania, East Prussia). Unfortunately, the territories lost to the USSR in the East (KresyKresy) were never returned to Poland.
