While the interest in Salafi-jihadism and the digital arena is not a new phenomenon, a limited amount of research has focused on the specific strategies and narratives disseminated by local groups and online supporter communities at the national and international level. The editors provide a brief introduction to the issue of Salafi-jihadism and digital media within the Swedish context, and further define the aim and research questions of the volume at hand. In addition, the current chapter defines some of the key concepts used throughout the volume, and further discusses some additional methodological considerations.
