Violence and the Formation of Social Statuses in the Prison Subculture. The text focuses on the relationship between aggression and the formation of social status in prisoners in selected prison with maximum security. The article is based on a sociological survey conducted from February to April 2022. A questionnaire survey among convicted men, classified as a prison with medium and high grade security, addresses the perception of risk of conflicts between prisoners, especially in terms of age differences and number of incarcerations. Methodologically, the text takes the form of a case study, mainly due to the complexity of obtaining valid data from convicted criminals. The main goal is to evaluate the level of threat to the life and health of prisoners and prison staff in the real environment. The article deals with the manifestations of aggressive behavior in the execution of the sentence and their reflection by prisoners. Part of the text does not cover only the typology of individual manifestations of the so-called prison violence, but also the presentation of diagnostics and monitoring of these excesses by the Prison Service of the Czech Republic.
