The Social Structure of the World Polity

World polity research argues that modern states are shaped by embeddedness in a network of international organizations, and yet the structure of that network is rarely examined. This is surprising, given that world polity theory implies that the world polity should be an increasingly dense, even, flat field of association. This article describes the social structure of the world polity, using network analysis of the complete population of intergovernmental organizations as it has evolved since 1820. Analysis of the world polity's structure reveals growing fragmentation, driven by exclusive rather than universalist intergovernmental organizations. The world polity has thus grown less cohesive, more fragmented, more heterogeneous, and less "small worldly" in its structure. This structure reflects a recent rise in the regionalization of the world polity.
