The present book stands out as a pivotal work on the interconnection between the root causes of Jihadi Salafi Groups (JSGs) and state fragility conditions and their amalgamated role in the formation and evolution of these organizations. It contributes to IR and international security debates by developing a comprehensive but readily understandable narrative of the rise of JSGs in Islamic countries, and examining them in an analytical framework in which their root causes are categorized on individual, group, and international levels.
