Violent Left-Wing Extremism and Terrorism

Violent left-wing extremism and terrorism remain significant forms of ideologically motivated violence. The phenomenon includes anarchist, communist, Marxist-Leninist, autonomous, and antifascist actors. CEP distinguishes between lawful political activism, broader ideological milieus, and violent and terrorist actors. It applies the analytical concept of violence-orientation, which refers to actors who commit or prepare violence, as well as those who support, endorse, or encourage its use. This conduct-based approach is intended to improve public understanding and support effective, evidence-based policy.

CEP’s current work focuses particularly on Europe and examines the ideological, organizational, and operational dimensions of this threat. Its research covers contemporary local, national, and transnational violent Antifa and autonomous networks, anarchist groups, and other manifestations of left-wing violence.

CEP analyzes how these actors recruit, communicate, mobilize, finance activities, select targets, and cooperate across borders. Key areas of research include violence against political opponents, attacks on police, infrastructure sabotage, transnational networks, youth mobilization, and the role of foreign fighters returning from the wars in Syria, Iraq, and Ukraine. CEP also examines intersections with antisemitism, anti-Israel mobilization, organized crime, and other extremist milieus.

A particular focus is the organizational flexibility of contemporary violence-oriented left-wing networks. Many decide against formal hierarchies or permanent membership structures and instead rely on personal relationships, trusted local groups, activist media platforms, and temporary operational cells. These structures can allow individuals to move between protest environments, political networks, support structures, and violent activity while complicating detection and disruption.
