A great deal of international and domestic conflict is driven by feelings of humiliation. But what does political humiliation consist of? In this chapter I argue that a key part of political humiliation involves the sense of being replaced. After looking at several case studies including the rhetoric used by ISIS recruiters, the rise of revanchist Russian and Chinese foreign policies, and the language deployed by white supremacists to frame and justify their grievances, I point to some features of the sense of replacement. These include the loss of status and perceived break of a promise or denial of an entitlement – both coupled with a reactionary brand of nostalgia that aims to return the world to how things were before these losses occurred. Part 1 introduces the idea of humiliation in international and domestic conflict. Part 2 uses four case studies to suggest that replacement is key in making sense of political humiliation. Part 3 offers several reasons why it’s particularly important to understand the dynamics of replacement.
