This title was first published in 2000: An investigation of how the claims of minority groups for greater political power through 'autonomy' and 'secession' clash with the concerns of the nation-State, and how States' refusals to respond positively to such claims contribute to the escalation of ethnic conflicts in contemporary multi-ethnic polities. In addition, this book examines the extent to which the international community is prepared to accommodate the concerns of minority groups beyond traditionally identified 'minority rights'. The validity of claims for autonomy with shared-sovereignty, autonomy as an inherent part of self-determination, autonomy as a solution to current ethnic conflicts, secessionist and irredentist movements and their impact on peace and security are analyzed in detail. Most importantly, whether minorities as such can secede from the State in which they live by virtue of self-determination is critically analyzed. The discussion of 'peoples' in the context of self-determination is the first detailed research on this subject to appear in international and human rights literature.
