This article develops a poststructuralist critique of the historical sociology of International Relations project. While the historical sociology of International Relations project claims to offer a more nuanced understanding of the state and the international, this article argues that it lacks critical reflection on the notion of a common ground on which ‘history’ and ‘sociology’ can successfully be combined. In order to problematize this ‘ground’, the article turns to Jacques Derrida’s critique of attempts to solve the history–structure dichotomy by finding a perfect combination of historicist and structuralist modes of explanation. Exploring the implications of Derrida’s critique, the article considers how the combination of ‘history’ and ‘sociology’ can be linked to a sovereign politics of time, which reaffirms rather than challenges the limits of the ‘modern’ political present and its relationship to the past, as well as the future. In response, it is suggested that a more radical critique is needed, one that seeks to disrupt the ‘modern’ political present and the contingent ground on which it rests.
