Abstract The ontological complexity of the twentieth-century Cold War motivates this special issue’s investigation of how social scientists conceptualize institutional novelty and change. We begin by noting the peculiar elision of the Cold War as an explanatory mechanism in mainstream sociology, even while sociologists have theoretical tools for making sense of the phenomenon: war , schema , field , world systems , and empire . All are useful; none are sufficient. We locate the explanatory problem in a tension between notions of structure and event that has organized debate in historical social science for several scholarly generations, and offer a new intellectual tool – medium durée – as a way forward. Medium durée describes phenomena that have sufficient cohesion as ideas and relationships to endure over time, yet remain sufficiently unfixed and ambiguous as to enable multifarious action and sensemaking. Our notion of medium durée is substantially informed by the articles and commentaries assembled for this special issue, which represent three years of dialogue among the authors as well as audiences in serial panels at the 2022 and 2023 annual meetings of the Social Science History Association.
