Prevention of radicalisation

Radicalisation is a phased and complex process in which an individual or a group embraces a radical ideology or belief that accepts, uses or condones violence, including acts of terrorism, to reach a specific political or ideological purpose. 

While radicalisation is not a new phenomenon, the trends, means and patterns of radicalisation evolve and responses have to be adapted. Home-grown lone actors and (returning) foreign terrorist fighters raise security issues and specific challenges for prevent work. Internet platforms, including social media, can be abused by violent extremists, terrorist groups and their sympathisers by providing new opportunities for mobilisation, recruitment and communication.

Project collaboration

Project based collaborations

The Project Based Collaborations are projects led by EU countries, with the support of the European Commission, to foster exchange and cooperation on priority topics on prevention of radicalisation.


Victims of terrorism

Victims of terrorism deserve special attention and support at national and EU level. This is done through specific laws, networks and cooperation with partner countries and international organisations.

Terrorist content online

Terrorists use the internet to radicalize, recruit, and facilitate carrying out terrorist attacks. The European Commission has put forward a series of voluntary and legislative measures and initiatives to help prevent this.

Preventing radicalisation

Terrorist content online

The continued presence of terrorist content on the web is a serious risk for security of citizens and to society at large. Terrorists misuse the internet to spread their messages to intimidate, radicalise, recruit, and facilitate carrying out terrorist attacks. To tackle this threat, the European Commission put forward a legislative proposal in 2018 for a Regulation to address the dissemination of terrorist content online, which was adopted by the European Parliament in April 2021. The Regulation sets clear and transparent rules applicable to online platforms established in the EU to ensure that:

  • when terrorist content is identified, it is taken down within the hour,
  • online platforms take measures to ensure that their services cannot be misused.

Strong safeguards are put in place to ensure that freedom of speech is protected. Learn more about the key elements of the regulation from the following factsheet:

The European Commission is also working in a voluntary public-private partnership with the tech industry to tackle new and emerging challenges under the EU Internet Forum.

EU Networks

To strengthen cooperation and the exchange of knowledge and practices between the different stakeholders taking part in the prevention of radicalisation and violent extremism, the Commission established a number of networks.

Networks involving the Commission

EU Internet Forum

The EU Internet Forum brings together the European Commission, EU and EFTA Member States, internet industry and Europol. Its main objective is to tackle illegal content online, in particular:

Radicalisation Awareness Network (RAN)

The Radicalisation Awareness Network (RAN) an EU-wide umbrella network connecting key first-line practitioners and field experts, now about 7000. They are social and health workers, teachers, exit workers, prison staff, civil society organisations, including victims' groups, as well as representatives from local authorities, law enforcement, counter terrorism specialists and academics. They exchange ideas, experiences, identify good practices and issue recommendations on how to best tackle all forms of radicalisation.

Network of prevent policy makers on radicalisation

The Network of prevent policy makers on radicalisation provides advice and expertise to the Commission in relation to the development of closer cooperation at EU level on EU prevent policy. This is done through the exchange of expertise and experiences, the implementation by Member States, at national, regional and local level, of EU prevent policy and through the exchange of expertise and experiences, project-based collaboration, study visits and voluntary peer reviews.

Other networks

European Strategic Communications Network (ESCN)

The European Strategic Communications Network (ESCN 2015-2019) was a network of EU countries, funded by the European Commission, which collaborated to share analysis, good practice and ideas on the sustainable use of strategic communications in countering violent extremism.

European Organisation for Prisons and Correctional Services (EuroPris)

The European Organisation of Prison and Correctional Services (EuroPris) is a non-political, non-governmental organisation founded in 2011. The initiative to establish EuroPris happened during the Swedish EU Presidency in 2009, and was brought forward by the European countries of the International Roundtable for Correctional Excellence.

European Prison Training Academies (EPTA)

The European Prison Training Academies (EPTA) was initiated in November 2008 at the French National Correctional Administration Academy (ENAP). It gathers training academies of Europe and promotes the exchange of good practices and debates on specific issues related to correctional training.

European Judicial Training Network

The European Judicial Training Network (EJTN) is the principal platform and promoter for the training and exchange of knowledge of the European judiciary. EJTN represents the interests of over 120,000 European judges, prosecutors and judicial trainers across Europe.

Cooperation and prevent strategies of EU countries

As part of the Counter-Terrorism Agenda adopted in 2020, the Commission will promote cooperation and dialogue with all security stakeholders, including EU security and intelligence services.

Many EU countries have developed strategies, action plans and other initiatives to tackle radicalisation. EU countries have also launched specific projects among like-minded member countries (so called Project Based Collaborations).
