In challenging conventional conceptualizations of the human subject, the state, and the international system, early feminist security studies (FSS) offered new ways to think about security from inside and outside the disciplinary boundaries of international relations (IR). Indeed, FSS scholars illustrate that security not only means different things in different contexts but also functions in different ways to constitute particular social/political realities. Politicizing the everyday, or rather, demanding that the everyday be recognized as political, is a core assumption of FSS. Further contributions of early FSS to the replacement of the human subject in matters of security include a form of engagement with the very language used in speaking of security matters. Moreover, FSS scholars argue that insecurities permeate the very condition of human existence, bringing FSS insights to bear on economic processes, technological development, state building, and reconstruction. Ranging from analysis of violent conflict and political violence using a gendered framework to critiques of the policies and practices governing post-conflict reconstruction, and encompassing strong and vital interjections on debates over securitizing development, migration, health, human rights, and peace, FSS scholarship is accessible, innovative, and by no means limited to “women and war.” Relocating FSS scholarship from the margins to the center and listening to the voices of those human subjects erased from the academic study of security brings new challenges but also new opportunities for collaboration, with the sighting and citing of FSS by other critical scholars.
