 This term was also used by Western media sources such as "The Times", both during the interbellum and immediately after World War II.It was later popularized by communist propaganda, which cited the prison as evidence that Poland's prewar government had been a "fascist" regime (despite the fact that Piłsudski had regarded fascism as a menace and that some of his government's most immoderate attacks had been directed against home-grown fascism).A number of modern non-Soviet sources have also characterized the facility as a concentration camp, including Yale University professor Timothy Snyder, the Library of Congress, Polish Nobel prize-winning author Czesław Miłosz, and historian Karol Modzelewski, who was political prisoner and one of the leaders of the democratic opposition in the communist Poland.
