This brief provides analysis of women’s advocacy for gender-balanced representation in diplomatic peace negotiations. It utilizes peace processes in the Democratic Republic of the Congo (DRC) as a case study, and highlights how Congolese women drew on international commitments and policy guidelines for women, peace, and security to mobilize across borders and advocate for their participation in the diplomatic peace processes. The brief also summaries the numerous challenges to women’s participation in formal peace processes, and how those challenges existed and were/were not overcome in the DRC process.
