Abstract
Islamic law denotes as haram any forbidden behavior, object, beverage, or food. Despite subscribing to a similar Salafi ideology, very few jihadi groups use violence against haram targets (e.g., brothels, casinos, statues, liquor stores, mixed sex schools, and gay clubs).
This study argues that haram-centered violence unites ethnically-mixed jihadi groups by fostering a superordinate Islamic identity that enables them to overcome their collective action problems. As a result, ethnically-mixed Salafi jihadi groups deploy haram targeting much more than homogenous ones.
Using new disaggregated group-level data, our analyses demonstrate that the ethnic structure of Salafi jihadi groups shapes haram targeting, both in Dagestan and on a global scale. The article discusses these findings and directions for future research on religious violence.
