How jihadist networks operate

A grounded understanding of changing organizational structures, activities, and involvement mechanisms of jihadist networks in the Netherlands


This criminological dissertation seeks to understand how jihadist networks function and develop over time and aims to answer the following research question: How did jihadist networks in the Netherlands operate between 2000 and 2013 and what changes can be observed? A jihadist network is defined in this thesis as an assembly of individuals that interact with each other during a particular episode, while conducting activities together that facilitate or establish a particular objective in which the Jihadi-Salafist ideology plays an essential role.
For analytical reasons, the broad phenomenon of jihadist networks is differentiated into three parts that will function as central themes in this thesis. These themes are underlying organizational structures of jihadist networks, activities conducted by the jihadist networks, and jihadist involvement mechanisms.

This thesis is published at Leiden University - Faculty of Law.
