E. H. Carr was one of Europe’s pre-eminent thinkers in the field of international affairs. Yet his contribution to International Relations theory is continually questioned. Realists depict Carr as a quintessential realist; revisionists draw from his wider corpus to qualify his contribution. Although not inaccurate, the revisionist literature is incomplete as it neglects a number of Carr’s diplomatic histories. Refocusing on these, especially the manner in which traces of Ranke’s ‘the primacy of foreign affairs’ tradition is evident, this article points to a more conservative and less critical Carr. Utilising an interpretivist framework, this shift in traditions of thought is explained by the dilemmas Carr faced. Although works of history rather than theory, the article contends that Carr’s diplomatic histories remain relevant, particularly with regard to the embedded criticism of realpolitik they contain. This realisation is made evident through a reading of Carr in parallel with the concept of tragedy.
