The Handbook is divided into seven self-contained chapters, which build on each other but also allow the reader to jump in at any point, depending on their interests. Specific content may also be found using the keyword index. The seven chapters are distributed between the Handbook’s two main parts, each of which has a specific focus. A third, supplementary section consists of a selection of additional articles on relevant topics. Part 1, consisting of Chapters 1 to 4, deals with the theoretical foundations of violent extremism prevention under the key topics of ‘theoretical references’, ‘phenomenology’, ‘radicalisation processes’ and ‘evaluation’. Part 2 comprises Chapters 5 to 7 and places the focus on violent extremism prevention practice in Germany. This section deals with the approaches practised here, existing prevention programmes and the current prevention landscape. Chapters 1 to 7, which cover what we could call the main body of violent extremism prevention, are supplemented by a third section comprising excurses into complementary questions and areas of society which, although not explicitly considered part of the field of violent extremism prevention itself, nevertheless influence the occurrence of radicalisation and the diverse manifestations of politically and/or religiously motivated extremisms. The topics touched upon there include conflict transformation, the media, criminal law, mobile counselling, civic education, football culture, Islamic associations, victim counselling and ethics.
