In late 20th-century Europe, both national and regional loyalties have retained a surprising strength and topicality, despite the advance of supra-national integration. This volume addresses some specific aspects of this phenomenon that lay at the centre of the interdisciplinary work of the first European Forum of the European University Institute in Florence during the academic year 1993/1994. It aims at contributing to a better understanding of the origins and the nature of territorially-based identities in Europe, and it also offers some analysis of current problems arising at various levels of the relationships between regional, national and international structures.
