Caliphate Calls to Arms. European ISIS Fighters in the Light of Sociological Analysis

The article concerns European volunteers travelling to Iraq and Syria to participate in armed jihad. It includes an analysis of propaganda materials prepared for potential ISIS fighters from Europe and the broadly understood West and the characterisation of the type of motives leading to the decision to travel to the territories occupied by the so-called Islamic State (the Caliphate). The theoretical system of reference was based on push-pull model combined with the cost-benefit theory which allowed to analyse this phenomenon in the context of the most popular theories of migration.
