At All Costs: How Relative Rebel Strength Affects PGM Sexual Violence in Civil Conflict

Abstract Does the military strength of rebel movements affect conflict-related sexual violence by pro-government militias (PGMs)? Existing studies on PGMs show the significant role that PGMs can have in shaping conflict dynamics and outcomes. What remains understudied is how the variation in power capabilities between conflict actors and the sources of support for PGMs influences civilian victimization by militia groups. We argue that strong rebels tip the balance of power against the state, making the state more susceptible to authorizing or allowing sexual violence by PGMs. In addition, the level of autonomy of PGMs from the government is likely to influence their sexual violence, conditional on rebel strength. When rebels are militarily strong, states are likely to order or tolerate sexual violence by PGMs that they train and/or provide resources to, thereby resulting in sexual violence by state-dependent PGMs. Examining all civil conflicts from 1989 to 2009 and using newly collected data on state-dependence of PGMs, our empirical findings provide evidence that PGMs are associated with higher levels of conflict-related sexual violence when the government faces strong rebels. Results also show that the likelihood of sexual violence by state-dependent PGMs increases when rebels exhibit strong military capabilities.
