This introductory article explores the multiple synergies between international practice theory and diplomatic studies. The timing for this cross-fertilizing exchange could not be better, as the study of diplomacy enters a phase of theorization while practice scholars look to confront the approach to new empirical and analytical challenges. The article first defines diplomacy as a historically and culturally contingent bundle of practices that are analytically alike in their claim to represent a given polity to the outside world. Then the key analytical wagers that practice theory makes are introduced, and debates currently raging in the discipline are briefly reviewed. Next, it is suggested what a practice theory of diplomacy may look like, discussing a variety of existing works through their common objective to explain the constitution of world politics in and through practice. Finally, a few research avenues to foster the dialogue between diplomatic studies and practice theory are outlined, centered on the nexuses of transformation and reproduction, rationality and know-how, and the technical vs. social dimensions of practices –diplomatic or otherwise.
Pouliot et al. (2015) studied this question.
