Paul Keal examines the historical role of international law and political theory in justifying the dispossession of indigenous peoples as part of the expansion of international society. Paradoxically, he argues, law and political theory can now form the basis of the recovery of indigenous rights. Arguing for the recognition of indigenous peoples as "peoples" with the right of self-determination in constitutional and international law, Keal questions the moral legitimacy of international society and examines concepts of collective guilt and responsibility.
