Abstract In his recent monograph, Territorial Status in International Law, Jure Vidmar offers ‘a new theory of statehood’ that consolidates his existing work and departs in important ways from legal orthodoxy. As a work of doctrinal law, the text is rigorous; however, its theoretical contribution is somewhat unclear. Vidmar’s central theoretical claim—that the status of individual states is established by discrete norms of customary international law—adds very little to his doctrinal argument. By examining his position, this review article examines what it might mean to provide helpful ‘theories of statehood’. It begins by framing the theoretical challenge posed by such work before setting out some desiderata for theoretical success in this area. Finally, it sketches out a general approach, grounded in Hannah Arendt’s conception of power, which offers a promising means for moving beyond doctrinal description within ‘reconstructive’ international legal theory.
