Overall Concept

The phenomena of radicalisation has developed at a high speed. From prevention to repression approaches, in looking for the right responses to these violent extremist expressions it is important to keep up with these developments. Understanding the different faces of radicalisation and extremism and the latest developments is a challenge for academics, professionals and policy makers. It demands a continuously updated data and interpretation. The complexity of the underlying processes and factors that lead different individuals and groups to adopt radical ideas and commit acts of violence forms a challenge as well.


The overall aim of PERICLES has been to develop a comprehensive approach to prevent and counter violent radicalisation and extremism. The PERICLES (Policy recommendation and improved communication tools for law enforcement and security agencies preventing violent radicalisation) project is especially dedicated to transitional processes of radicalisation. To meet its aims, PERICLES has considered violent left-wing and right-wing as well as religious ideologies. A special focus has also been placed on the risks connected with digital violent propaganda. The PERICLES project has delivered advanced and validated counter-propaganda techniques that are target-group-specific. Furthermore, the cooperation between relevant authorities who have due regard against violent radicalisation or support the process of de-radicalisation has been enhanced through the use of the project outputs. The comprehensive PERICLES prevention strategy largely addresses law enforcement agencies (LEAs) and security agencies; but will also find use by prisons and social workers, teachers and even relatives of affected people.

Specific objectives

PERICLES had an ambitious but achievable research agenda that resulted in significant advancements in the radicalisation prevention and countering domain. This was primarily achieved via the use of the PERICLES toolkit, which contains a suite of practical tools.
