From the Middle East, through Africa to South East Asia, today’s jihadi movement is more fragmented than ever. Al-Qaida and the "Islamic State" compete not only with each other but also with local jihadi groups. Despite the fact that, in the wake of the "Islamic State", international jihadi groups are in fierce competition for supporters, little has been said on how the process of competition as well as external events changed the ideology of these groups and the topics relevant to them. Countering dominant research focusing on the differences between jihadi strains, this book explores how the appearance and temporary strength of the "Islamic State" changed the topics and talking points of other jihadi actors, such as al-Qaida. By analyzing primary sources in Arabic and English, the author sheds light on the inner- and inter-jihadi discourse and its development over the years. The book does not simply describe changes in topics; it traces these changes quantitatively and relates them to external events. This book is aimed at academics, researchers, and postgraduate students interested in political science, security studies, jihadism, jihadi discourse, al-Qaida, "Islamic State", and Salafism, as well as practitioners and decision-makers in government agencies who wish to understand how transnational jihadi discourse has developed over the previous two decades.
