Extant studies on post-conflict peacebuilding have glossed over the critical roles women societies played in post-war reconstruction and peacebuilding among the Igbo of southeast Nigeria. This oversight is unacceptably surprising, given the enormous impact of Umuada women and Women August meeting in peacebuilding and social change. Using a combination of survey and case study research designs, the study seeks to examine their impact and challenges by re-constructing the history, throwing light on the structure, functions, potentials and modus operandi, and examines the nexus between the Women August Meeting and Umuada Women. It further highlights factors that inhibit these women in further negotiating a space in the public sphere. The study will be both qualitative and quantitative in nature and approached from a gendered perspective. The study proposes that women be involved and their potentials fully harnessed and made central to national security policies as a key to sustainable peace.
