In what ways is the concept of sovereignty changing today? Where is this change leading us - toward further international integration or toward greater subnational fragmentation? What will be the implications of this change for international security, peace, and justice? Will the emergence of new sovereign states for old ethnic groups lead the world toward greater order and justice or, rather, toward greater anarchy, violence and repression? The seven essays in this volume address these issues from historical, political, legal, ethical and sociological perspectives. Moreover, they survey applications of sovereignty in the West European, post-Communist, Islamic, and East Asian contexts. Contributors are: Gregory H. Fox, James Gow, Sohail H. Hashmi, Beatrice Heuser, Daniel Philpott, Miranda A. Schreurs, and Kamal S. Shehadi.
