Abstract

Contrary to historical terrorism scholarship, terrorist groups can strategically diversify into a variety of criminal activities without losing their core ideology or support among the civilian population. This pattern is demonstrated by the evolutionary arc of al-Shabaab, which grew from a small subset of Somalia’s Islamic Courts Union to the most violent political actor in the Horn of Africa, able to conduct terrorist attacks as far afield as Kenya, Djibouti, and Ethiopia. Al-Shabaab has been highly successful in creating a narrative of truth and justice provision while simultaneously exploiting the Somali population and engaging in criminal activity. For the group, criminal activity and crime networks serve two primary purposes: as a funding mechanism and as an avenue for recruitment. Using ethnographic fieldwork and process tracing, I find that the group’s criminal activities throughout the Horn of Africa have made the group significantly more resilient to counterterrorism and counterinsurgency campaigns, extending both its lifespan and operational capability.
