This report presents research carried out within the project (Ku2016/01373/D – Uppdrag till Totalförsvarets forskningsinstitut (FOI) att göra kartläggningar och analyser av våldsbejakande extremistisk propaganda) that has been assigned to the Swedish defence research agency by the Swedish Government. The project will continue until March 2019. The purpose of this report is to highlight various aspects of IS’s digital propaganda; How it is spread, what its content is, how the content varies over time, and how images are used in the propaganda. We have also studied the role of women and children in IS-propaganda, and how a youth culture called Jihadi cool has evolved with its own kind of clothing, music and cultural expressions. IS’s propaganda contains a variety of religious concepts and references, which IS sometimes use in a non-traditional way. Therefore, a chapter in this report describes how Islamic politico-religious language can be used to convey different kinds of messages
