'A creative, insightful, and wide--ranging introduction to the history of international political thought, emphasizing issues of identity, inclusion, and exclusion in international society. Keenea s overview of the field is at once eminently accessible to advanced undergraduates and stimulating, even challenging, to professional scholars. Time and again, familiar authors and issues appear in a new and fascinating light.' Jack Donnelly, University of Denver 'This is a learned and valuable overview of key concepts in the history of international political thought. Keenea s focus on changing conceptions of how communities should be held together and separated from the rest of humankind provides a distinctive approach to international political thought over two millennia. All those who are interested in the linkages between political theory and international relations will profit from reading this important addition to the literature.' Andrew Linklater, University of Wales
