This chapter explores different ways of knowing international politics, with a focus on violence as one of its key structuring modes. The meanings of core categories in international politics are not static but linked to specific knowledge frameworks. Different epistemic practices shape which knowledges get prioritized while others get obscured. Epistemological choices matter greatly in constituting understanding and expertise. This chapter contributes to working out knowledge politics and epistemic hierarchies in International Relations (IR), which often remain implicit or hidden, by using the example of violence. Violence is essential for the making and remaking of states and shapes international orders. Underlying structural forms of violence, related to gender, class, and race, determine the lives of communities and individuals in conflicts and beyond, in the mundane (socio-economic) workings and routines of international politics. In elaborating on everyday, expert, and academic ways of knowing, the authors make the multitude of knowledge frameworks that shape international politics as well as research explicit and caution against the risk of perpetuating violence as a structuring element of the discipline of IR itself.
