This study examines the Polish repression apparatus from 1944 to 1956, tracing its development within the framework of Soviet-controlled governance. Using a political science perspective, it investigates the mechanisms of state terror, ideological control, and institutional repression that defined the Polish People's Republic (PRL) during its formative years. Drawing on historiographical sources, the analysis is structured around the classical definitions of totalitarianism, particularly the models proposed by Carl J. Friedrich, Zbigniew Brzeziński, and Hannah Arendt. The findings demonstrate that postwar Poland adopted Soviet-style state structures, including mass surveillance, systemic purges, and ideological coercion, facilitated by the Ministry of Public Security (MBP). The study also explores the transition from Stalinist repression to the relative political thaw of 1956, highlighting the role of the Poznań protests and the rise of Władysław Gomułka. Despite the relaxation of some oppressive measures, the study concludes that while Poland evolved from a strictly totalitarian model to a more authoritarian regime, elements of systemic repression persisted. These findings contribute to the broader discourse on totalitarian governance, political transformation, and the role of security institutions in shaping postwar Eastern Europe.
