What explains why pogrom organizers carry out violence against certain groups, but not others? Pogroms begin when the “top-down” organization of the episode converges with “bottom-up” violent mobilization by an informal group. In my dissertation, I find that pogroms follow a symbolic logic because different types of political order determine how organizers of these episodes mark certain groups as objects of social exclusion by engaging in public, targeted violence against them. The interaction between the state’s variable involvement in the organization of group-targeted violence, on the one hand, and organizers’ prior capacity to mobilize violence, on the other, leads to four different types of political order: (1) consolidation; (2) contestation; (3) state-building; and (4) anarchy. In turn, these different types of political order generate four separate patterns of group targeting.

I test different explanations for group targeting and within-case spatial variation in violence during four archetypal pogrom episodes: (1) the antisemitic Kristallnacht pogrom in Nazi Germany in November 1938, which represents a consolidated context; (2) the pogrom against Mexican nationals in Brownsville, TX, in 1915, in a state-building context; (3) the anti-Black pogrom in East St. Louis, IL, in July 1917, where non-state groups contested the state’s capacity for mobilization; and (4) the pogrom against Afro-Caribbean residents of London’s Notting Hill neighborhood, where neither state actors nor non-state groups exercised a significant priority over violence. I use process tracing to explain top-down group targeting by organizers, and spatial regression analysis to analyze how participants spread violence from the bottom-up. These analyses draw on novel applications of archival materials about violence and its determinants, including press accounts, census records, police reports, organizational documents, and municipal records.

My work on pogroms contributes to multiple strands of scholarship in political science, sociology, and history about the origins and dynamics of violence and contention. Theoretically, this research illuminates how symbolic action—collective, public activities that reinforce political order and intergroup relations—patterns of political violence. The project also contributes to the broader constructivist research agenda in comparative politics by elaborating on the mechanisms by which violence emerges from and calcifies boundaries between ethnic groups.

Below is a list of published and in-progress works that make up my ongoing research agenda on these and closely-related topics. If you’re working on these issues as a scholar, policymaker, practitioner, or activist, and want to collaborate, please reach out at
