This chapter introduces the theme of gendered knowledge production and proposes new understandings of epistemic agency, epistemic power and epistemic violence. These theoretical concepts are employed to critically approach the Women, Peace and Security agenda as a system of knowledge that comes with both possibilities and constraints. The chapter conceptualizes epistemic agency as embodied and narrative. By taking the embodied and narrative epistemic agency of ‘knowers’ seriously, new insights are forwarded about the role women play in producing knowledge about war. To expand and deepen understandings of violence and war, we engage in a feminist mapping of ways, sites and times of knowledge production highlighting women’s experiences, epistemic power and agency.
