This article attempts to trace and characterize Maria Dąbrowska’s interest in the so-called Western Territories, ie. the eastern provinces of the German Reich handed over to Poland in 1945 as part of the post-war settlement. The analysis, based on the text of her Diaries, tries to establish the relative size and importance of her references to the WT, identify their themes and their contemporary social, political and cultural contexts. The article also examines Dąbrowska’s more or less explicit judgments of the policies of Poland’s postwar communist government with regard to the Western Territories
