The recent economic crisis has witnessed a surge in demonstrations and other protest actions all over Europe, while in the most affected countries—such as Greece—the use of personal violence and damage of property became an everyday phenomenon. What are the drivers of violent political action in times of crisis? How do these drivers interact? And to what extent does context matter? These questions are examined in the light of a new and original survey data set carried out across nine European countries, all affected to different degrees by the financial crisis. Four theoretical paradigms from social movement research that account for violent political action are examined. This study looks beyond the staple explanations of relative deprivation and resource mobilisation, expands the analysis to include a relational approach—namely, conflictual irrelevance—and explores the soundness of an integrative approach that attempts to reconcile the traditional divide between grievance and resource-based models. By measuring actual behaviour rather than merely intention, the article furthermore contributes to the discussion over the participation of individuals in violent activism and gives empirical support to the dual-pathways model of collective action for the understanding of violent political action during times of crisis.
