Development policies advancing the Women, Peace and Security agenda enjoy an established trajectory across international organizations. This is evident within United Nations programs that engage displaced populations where children are particularly vulnerable to conflict dynamics. This article argues that existing gender-based development policies mitigate the impact of conflict on children through empowering displaced women as peacebuilding agents. Using United Nations data, fieldwork, and elite interviews, this article employs a case study of Iraq to show that the implementation of gender-based development policies correlates with reduced rates of grave violations against children in conflict settings. These findings point to the peacebuilding potential of displaced women through their ability to mitigate the economic and social impacts of conflict dynamics on children. Policy programs within the United Nations Women, Peace and Security framework should engage this connection between displaced women and the protection of children to strengthen and improve peacebuilding outcomes in conflict environments.
