ABSTRACT
Justin Rosenberg rightly highlights the paucity of International Relations’ (IR) influence in other disciplines, and selected works in historical sociology demonstrate the significance of the international to others whilst also revealing problematic understandings of the international itself. In this regard, Rosenberg’s intervention is welcome. However, in staking the disciplinary credentials of IR on ‘societal multiplicity’, Rosenberg inadvertently exposes IR as part of a wider convergence on the ontological importance of relations (rather than substances) across the social sciences. Historical sociology scholarship also reveals the international to be but one part of an interconnected, multi-scalar social world that is shaped by multiplicity across all scales; multiplicity and relations permeate social scales. By exploring the Czechoslovak Corps in the Russian Revolution, the article broadens Rosenberg’s multiplicity whilst also revealing the paradox of a multiplicitous IR: the more IR acknowledges multi-scalar relations, the less distinguishable it becomes from the other social sciences.
