The phenomena of radicalisation today develop and change at high speed, with their extreme forms manifested globally. The destructive dimensions of (violent) Islamist or right-wing radicalisation have become dramatically visible in Europe posing serious challenges to European societies at large. This report aims to address a knowledge gap with regard to how and to what extent internationally observed radicalisation processes are manifested in Bulgaria. Four different forms of radicalisation are investigated, including Islamist radicalisation, right-wing and left-wing radicalisation, as well as football hooliganism. The report provides policy makers and the expert community with a systematic overview of the main risks to which the Bulgarian society is exposed, as well as of the main actors and ideas, the repertoire of actions and the groups at risk associated with radicalisation. The report outlines recommendations for improvement of the policy and institutional response with regard to radicalisation by way of monitoring and prevention measures as well as multi agency collaboration and community engagement.
