This book explores the online strategies and presence of Salafi-Jihadi actors in the Nordic as well as the international context. Global Salafi-jihadism has been at the epicentre of international focus during the past decade. This book explores how the Swedish and other Nordic Salafi-jihadist sympathisers have used social digital media to radicalise, recruit, and propagate followers in relation to foreign terrorist fighters (FTFs) and online communities. The chapters in this volume unpack different perspectives of Salafi-jihadi communications strategies, as well as how the international Salafi-jihadi community has constantly reconfigured and adapted to changing security conditions. The case studies of the Nordics constitute a microcosm of wider Salafi-jihadi narratives in relation to the rise and fall of the Islamic State’s so-called ‘digital caliphate’. This book will be of much interest to students of terrorism studies, counter-extremism and counter-terrorism, social media and security studies.
