ABSTRACT
During the approach of the Red Army towards the Oder, Stalin, Roosevelt and Churchill took a range of decisions at the Yalta Conference concerning the course of the new borders of Europe. For the Polish government, which had not been invited to the conference, its resolutions were shocking. The Soviet Union received permission to annex Poland’s eastern borderlands, which had comprised 46% of the territory of the pre-war Polish state. The position of Poland regarding the Oder region in the first half of the 20th century should be perceived in the spirit of nationalist feelings spreading throughout Europe. Before the German attack on Poland, factual works written by her appeared in the field of geography-anthropology devoted to East Pomerania and Wielkopolska. Following the collapse of the Warsaw Uprising in October 1944, Wojciechowski convinced members of the ‘Fatherland’ resistance group, which had been loyal to the Polish government-in-exile up to then, that a change in strategy was needed.
