This chapter outlines feminist contributions to and critiques of scholarship on peacebuilding. It provides an overview of the policy framework supporting gender-sensitive peacebuilding, and explains how that framework is being operationalised. The chapter focuses on the core peacebuilding institutions that operate in the international system, and evaluates key challenges facing peacebuilding enterprise in the coming years. The gendered politics and practices of peacebuilding have been analysed in meticulous detail by feminist scholarship that seeks to examine agency, particularly women's agency in post-conflict societies. The chapter identifies some feminist works on peacebuilding an emphasis on equality of formal and informal institutional access. The policy initiatives facilitating the creation of gender-sensitive peacebuilding include disarmament, demobilisation and reintegration (DDR), and security sector reform (SSR). Finally, the chapter focuses on the United Nations peacebuilding institutions, namely the Peacebuilding Commission, the Peacebuilding Support Office, and the Peacebuilding Fund.
