This study examines women’s political participation in peace negotiations, focusing on four cases where women have gained access to high-level official negotiations. Each case study – Northern Ireland, Guatemala, Kenya, and the Philippines – is framed by eight overarching research questions: Why did women mobilize for peace? How did women mobilize and organize to gain access to high-level peace negotiations? How did they form coalitions and alliances? How did they assemble and shape agendas? How did they set priorities for their activities? How did their priorities change when they participated in high-level peace negotiations? How did they negotiate their goals? And, to what extent were their objectives or priorities represented in the resulting peace agreement?
