This study explores the evolution of the Polish prison subculture before and after the political upheaval of 1989, marking the transition from communism to a more democratic and open society. It examines how these systemic changes influenced the informal hierarchies and social structures within prisons. Under the communist regime, prisons were spaces of severe repression and control, where the inmate population was strictly managed through a combination of intense surveillance and punitive measures. Inmate labor was exploited, and any form of dissent was brutally suppressed, fostering a distinct subculture among prisoners known as ‘grypsmen.‘ The fall of communism brought significant reforms to the penal system, aiming to improve conditions and reduce inmate exploitation. However, the remnants of old subcultures persisted, adapting to the new sociopolitical environment. This paper delves into the continuity and transformation of these subcultures, shedding light on the social dynamics that govern inmate interactions and the unofficial codes that continue to influence prison life in post-communist Poland. The research highlights the resilience and adaptability of subcultural norms amidst sweeping changes, offering insights into the complex interplay between structure and agency in closed institutions.
