This research analyzed both micro and macro dimensions and the structural and agency components of the Bosnian genocides and found that the perpetrator groups became more violent as they went through the violentization process within a society that transformed into a rigid and enmeshed system. The violentization process involves four stages: 1) brutalization—witnessing, learning and experiencing violence; 2) defiance—using violence to stop violence; 3) violent dominant engagements; 4) virulency—violence and dangerous selves; and 5) extreme virulency—torture, rape, and mass murder, added to address violent behavior that goes beyond killing to include torture and mutilation. The violentization theory was used to examine the micro dimensions of the genocides, while the circumplex theory was used at the macro level to address how organizations and social groups engaged in genocidal behavior in Bosnia. Data on the Bosnian genocides were collected from court transcripts, professional research reports, human rights reports, and books. Texts that provided information about the social conditions and the actions of perpetrators during the Bosnian genocides were also examined. Directed content analysis of the data was used to test the fit of the two theories with the Balkan genocide cases. Limitations of the study are discussed and recommendations for future research are presented. Figure, references
