This paper critiques a core premise of Global IR: the association of knowledge with geography, which we term geo-epistemology. It argues that ‘American’ and Global IR share a Eurocentric spatial imaginary, one that was a product of Western expansion and empire. Through its geo-epistemology, Global IR enables a conservative appropriation of the critique of Eurocentrism in IR. Globality becomes a matter of assembling sufficient geographic representation rather than an analysis of the discipline's political, historical, and spatial assumptions. Anglo-American policymakers and intellectuals invented the national/international world to replace the world of empires and races that came apart in the era of the world wars. This UN world of sovereign nation-states and their regional groupings was the foundational move of both what Stanley Hoffman called ‘the American social science’ – IR – and the American-centred world order. The paper uses the reception and legacy of Hoffman's classic essay to show how culture replaced power and history in the study of the discipline, obfuscating the Eurocentrism of Global IR.
