This article presents the history of Masuria created by the propaganda of socialist realism. Itsaim is to show how writers presented the nationality-based verification campaign and opinion pollsin the area of former East Prussia. The author attempts to prove that social realist writers describedthe above-mentioned action as “discovering” Polish identity by the inhabitants of Masuria. In orderto do that, four stories included in the anthology Ziemia serdecznie znajoma, published in 1954, areanalysed to show that strong pressure was exerted on the Masurians to confirm their Polish nationality.
