While research increasingly recognizes the importance of civilian agency and strategies in influencing conflict dynamics and reducing civilian victimization in the context of armed conflict, research has until now not investigated whether civilians also have the capacity to limit organized criminal violence. This study thus aims to answer under which conditions civilians can protect themselves from and influence levels of organized criminal violence and draws on the literatures on civilian self-protection and autonomy strategies in the context of armed conflict, as well as on organized criminal governance and violence. I argue that civilian communities with high levels of social organization will experience lower levels of violence, as they are more likely to mount successful collective strategies that influence costs and benefits for organized crime groups to use violence. Using the method of structured focused comparison, this hypothesis is tested on the Colombian municipalities San Juan de Arama, Vistahermosa and Granada. The results show some support for the theorized relationship. In general, municipalities with higher levels of social organization experienced lower levels of organized criminal violence, but this relationship appears to be moderated by levels of civil war violence. Due to the explorative character of this study, more research is warranted.
