This Article offers an alternate account of federalism’s late eighteenth-century origins. In place of scholarly and doctrinal accounts that portray federalism as a repudiation of models of unitary sovereignty, it emphasizes the federalist ideology of dual sovereignty as a form of centralization—a shift from a world of diffuse sovereignty to one where authority was increasingly imagined as concentrated in the hands of only two legitimate sovereigns.
