The discipline of international relations (IR) is traditionally concerned with the spatial dimension of politics and the territorial borders of states. This chapter focuses on a point for thinking about time and IR: the relationship between time and space. It considers the work that history does as a technique and a practice of inscribing borders in time', which are used in order to separate the past from the present and the future. The chapter explores some recent attempts to explore what these other experiences of time might refer to and how they manifest themselves in contemporary world politics. Assumptions of time play a crucial role in IR not least because they help constitute ideas about the temporality of international politics and the temporal direction in which interstate relations are heading. One prominent example of how to think the political significance of time beyond the limits of IR is James Der Derian's book Antidiplomacy.
