FOREIGN FIGHTERS - A PREDICTOR OF CONFLICT-RELATED SEXUAL VIOLENCE? : A quantitative study on how foreign fighters impact the occurrence of conflict-related sexual violence perpetrated by rebel groups

Abstract: Why do some rebel groups perpetrate conflict-related sexual violence (CRSV) while others do not? A growing body of research has suggested various explanations, but offers no consensus regarding this puzzling question. At the same time, recent studies have recognized how foreign fighters impact rebel groups’ violence against civilians. Yet, to what extent the presence of foreign fighters could also explain rebel-inflicted CRSV remains unexplored. In this study, I argue that rebel groups with foreign fighters are more likely to perpetrate CRSV than rebel groups without foreign fighters, based on two causal mechanisms. Firstly, foreign fighters pose a risk to the internal cohesion of rebel groups, which is why CRSV is initiated as a socialization tool. Secondly, foreign fighters alleviate the rebel groups dependency on the local civilian community, thereby enabling such violence. The results from logistic regressions, based on a sample of 45 rebel groups between 1989 and 2014, indicate that there is indeed covariation between the presence of foreign fighters and CRSV occurrence. The findings contribute to the ongoing scholarly debate trying to explain variations in CRSV, as well as to the emerging field of foreign fighters' effect on violence against civilians. The results also have relevant policy implications for the international efforts in preventing CRSV.
