The academic study of conflict resolution was born as as a critique of mainstream International Relations (IR), which explains why feminist theory and conflict resolution share many things in common. For example, both feminists and conflict resolution scholars challenge traditional power politics grounded in realist or neorealists analyses of conflict. They also share the core belief that war is not inevitable and that human beings have the capacity to resolve conflicts through nonviolent means. In the past two decades, with the expansion of feminist scholarship in IR, feminist interventions in conflict resolution have gained more currency. This essay reviews feminist scholarship in conflict resolution, with particular emphasis on five elements: critiques of the absence and/or marginalization of women in the field and an effort to include women and to make women visible and heard; articulation of a unique feminist standpoint for approaching peacemaking and conflict resolution, which is essentially different to, and qualitatively better than, mainstream (or male-stream) perspectives; feminist theorization of difference in conflict resolution theory and practice (challenges to essentialism, intersections, power and privilege, culture); feminist redefinition of central concepts in the field, especially violence, power, peace, and security; and original feminist research and theorizing, including field research in conflict areas, designed to transform rather than just reform the field. This essay argues that in order to further expand and institutionalize conflict resolution studies, mainstream scholars must be willing to engage seriously the contributions and critiques of feminists.
