German Institute on Radicalization
and De-radicalization Studies


Welcome to the new homepage of the German Institute on Radicalization and De-radicalization Studies (GIRDS). As the first German research and network initiative focusing solely on the theory and practice of de-radicalization and counter-radicalization GIRDS is completely non-profit and independent. We are not institutionally bound and do not follow any partisan politics. GIRDS can be seen as transparent network of experts both from practical backgrounds and the academia aiming to foster the theoretical and practical development of de-radicalization methods, evaluation tools, training manuals, and concepts. GIRDS is open to all interested practitioners and researchers and we encourage you to contact us if you would like to participate and join us in striving for a free exchange of experiences and ideas to make de-radicalization and counter-radicalization more effective and sustainable.
GIRDS is also the only German network in the field certified by the ISDEP standard in recognizing radicalization and appropriate intervention. Daniel Koehler, Founder and Director

New Database on Jihadist Terrorism in Germany

In addition to the Database on Terrorism in Germany (DTG) for right-wing extremism we have now completed the first dataset analysis for Jihadist terrorism in Germany (DTG-JI). Our current dataset includes 40 Jihadist terrorist plots and attacks on German soil since 2001 that caused a total of 14 casualties. We only included those plots and attacks that were directed against Germany and hatched from within the country. We excluded those plots that were directed against other countries or individuals outside of Germany (even if the plot originated in the country), as well as ‘membership’ crimes (i.e. membership in a foreign terrorist organization like ISIL), if the charges did not also include plotting, preparing or conducting a terrorist attack. We also excluded those plots against Germany being made from another country, if the plot did not lead to an attack on German soil, for the lack of information. Like for our DTG-RWX dataset we used a wide collection of information sources, such as court documents, verdicts, press articles, intelligence reports and interviews with formers.

We will continuously update the dataset whenever new plots or attacks happen. Currently, we work on preparing an analytical report about the main characteristics of Jihadist terrorism in Germany for publication. Due to a lack of funding we are currently not able to provide a full online based and searchable database.
