Violent ideologies/terrorism are predicted to increase in Sweden. However, there is no specific terrorist profile. Both children, young people and adults are exposed to indoctrination that violence solves problems. The police authority is responsible for r educing crime in Sweden but needs to cooperate with other actors for the work to be successful. The Church of Sweden cooperates with the primary school through Riddarskolan. The leaders teach the students about ethics, to strengthen their self esteem and t o counter bullying. In 2004, Malung's parish received a prize from Ickevåldsfonden for the work with Riddarskolan with the justification that the work successfully counteracts violence. This qualitative content analysis is based on collected material about Riddarskolan, from two of the Church of Sweden's parishes. The purpose of this study was to investigate whether Riddarskolan and its leadership can be part of crime prevention, against terrorism. The result shows that not only crime prevention, but also terrorism and leadership are complex phenomena, which require complex solutions and answers. The answer to the qu estion of whether Riddarskolan can function preventively in terms of terrorism is thus not clear cut. On the other hand, it is possible to understand that leadership has a significant role in the direction in which we develop as humans Our development tak es place in interaction, cooperation and in community with other people. In order to further understand the importance of cooperation between different actors, as well as to better understand terrorists' motivation, dynamics, its causes and manifestations, further research is needed on the importance of leadership in crime prevention
