This chapter interest is based on the way that political divisions are embodied through governing institutions allowing radical ideas to emerge and gain prominence. This includes radical narratives of exclusion, segregation and discrimination that can be identified in the education sector and institutionalised through the “two schools under one roof” that implies two separate schools (pupils, teachers, and technical staff) which use the same teaching space. Consequently, two high schools labelled as “two schools under one roof” in Central Bosnia Canton represent the first case study of this chapter. Results highlight that education systems that encourages exclusive worldviews, insisting and resting on artificial divisions can become fertile ground in the development of extreme behaviors. The second case study is focused on organized groups of football fans since political ideas and ideologies are closely linked to the subcultures in Bosnia and Herzegovina, especially sport fans’ groups. Results indicate that the animosity that members of those groups show towards the political system, represented mostly through police forces and towards ruling politicians, is the most vivid indicator of potential radicalisation. Since the importance of digitalisation was stressed as a major factor of radicalisation in Bosnia and Herzegovina (BiH), primarily because it represents a largely unregulated sphere from the standpoint of institutional responsibility, the final empirical study included youth supporters of online Salafi influencers. Results show that in addition to the strong influence that the community can leave on the individual, in terms of agreeing with a large number of views and opinions, there are still individual understandings and attachments to topics that the individual perceives as important.
