This article discusses the relation between state violence and public disorder under authoritarian rule in Poland. Focusing on the major crises and protests of the communist era, it examines regime violence through a double perspective – on the one hand, the way the regime resorted to physical violence to uphold its survival and, on the other hand, as a generational experience of those who suffered from it. Despite the state's use of physical violence until 1989 becoming more rationalised, modernised and efficient, it also turned less effective over time. This evolution contributed to a decreasing risk factor for protesters vis-à-vis the state. Since the bulk of those who participated in protests and riots were young people, the focus lies on the youthful dimension of public disorder and in particular the activity and experience of then students and young workers.
