My research centers on the dynamics of pogroms, which I define as relatively brief episodes of multiple, public violent acts by an informal group against a specific social community. My research on pogroms builds on multiple literatures in the fields of political science, sociology, and history about the origins and dynamics of violence, contention, and social movements. Empirically, I focus on historical cases of pogrom violence in the United States, the United Kingdom, and Nazi Germany. This research raises important descriptive and causal questions about political violence, such as:

  • Why do pogroms occur, and what explains variation across cases in social relations between pogrom organizers and the groups they target?
  • What explains why pogroms result in violence in some places, but not in others?
