Gender provisions have the overarching goal of enhancing gender equality, however few peace agreements include strong gender provisions. The presence of strong gender provisions in ceasefire agreements has crucial implications in the immediate and post-conflict phase in improving women’s situation. I use structured, focused comparison in this study to explore when and how strong gender provisions on violence against women are adopted. I focus on conflicts with a high prevalence of sexual violence and contexts where women mobilize in the conflict to advocate for women’s rights. I demonstrate the relationship between international involvement and strong gender provisions. I argue that in civil wars with a high level of international involvement in support of peace, ceasefire agreements are more likely to include strong gender provisions on violence against women. This is possible through the mechanism of international actors serving as brokers for the women’s movement that is already mobilized to access and influence the peace process. This mechanism is particularly crucial for autocratic countries where women’s mobilization is not sufficient to lead to strong gender provisions. However, the findings are applicable to countries with other regime types.
