Why has English School theory, even as it has been re-imagined as critical international society theory, ignored the workings of gender in international politics? This article stages an encounter between the English School and feminists in International Relations (IR), first demonstrating the broad compatibility of the two approaches. I argue that to conduct a conversation between English School and IR feminist approaches, it is necessary to reconstruct the English School's three traditions – Realist, Rationalist, and Revolutionist – so as to allow a greater role for gender as a category of analysis. I then review the work of two key English School scholars, Hedley Bull and Barry Buzan with this reconstruction in mind. Finally, I argue that IR theorists who have participated in the recent English School revival should consider integrating gender into its theoretical and research agenda, and show several examples of how a hybrid approach can be brought to bear on the expansion of international society, diplomacy, and human rights.
