This essay analyzes how female participation may affect the perpetration of conflict-related sexual violence (CRSV) by rebel groups. I look at leftist, Islamist, Christian, and Buddhist rebel groups, examining how these ideologies interact with the factor of female participation. I hypothesize that while female participation in leftist and Buddhist rebel groups may reduce CRSV, it may have relatively little impact in Islamist and Christian rebel groups. I test these theories individually through the case studies of the Farabundo Mart National Liberation Front (FMLN), the Islamic State of Iraq and the Levant (ISIL), the Lord's Resistance Army (LRA), and the United People's Democratic Front (UPDF). Due to the lack of data on Christian and Buddhist rebel groups, I only statistically corroborate my hypotheses on leftist and Islamist rebel groups.
