Abstract

The history of interdisciplinarity in international relations (IR) is not a simple narrative. Initially a transdisciplinary meeting place for scholars from many disciplines, IR developed after the 1940s into a closed sub-discipline of political science, and only after 1980 did it once again engage with other disciplines in a sustained way. This article traces these 'three ages' of IR, and concludes with a case study of the emerging historiography within IR.
