On May 8 and 9 the University of Trier’s Departments of Law and Psychology hosted their first interdisciplinary and international conference on the legal and psychological aspects of violent and non-violent radicalization processes, potentially leading to severe criminal acts or terrorism. Attended by over 90 professionals, the event brought together many, nationally and internationally, highly renowned experts in this field from numerous disciplines such as law, sociology, social psychology, and political science, as well as various students and practitioners. Recognizing the necessity and importance of the topic for the German legal system, judges from the German Federal High Court of Justice and the German Federal Constitutional Court attended the conference to follow the panels and discussions.
