Abstract
Extremism is a phenomenon that reflects the state of contemporary society. It is a worldwide phenomenon and a problem that permeates all social strata.
Radical attitudes and activities of extremist groups also naturally penetrate the prison environment. Prison as an example of a total institution is a breeding ground not only for the propagation of extremist ideas, but also primarily for recruiting individuals who appear to be suitable followers and recruits for subsequent participation in the group's activities.
The prison environment uses primarily the vulnerability of these potential recruits and their identity transformation, which is associated with the total character of the prison.
