While scholars on gender provisions have focused on why and how this type of peace agreement clause gets incorporated, few studies have sought to improve our understanding of the implementation process. Addressing this gap empirically, this study utilizes unique interview material to analyze the initial stages of realizing the 2014 Comprehensive Agreement on the Bangsamoro in the Philippines. The article bridges and expands on key theoretical insights based on three explanations suggested by previous research: 1) state capacity on promoting gender equality; 2) the mobilization of women’s organizations; and 3) gender awareness of international actors. We find that the strategic actions of women’s organizations combined with state capacity accelerated the implementation. However, their influence was dependent on whether or not the government prioritized the gender provisions, and whether international actors provided financial support to the agreement infrastructure.
