This collection was inspired by the international conference "Dynamics of National Identity and Transnational Identities in the Process of European Integration", organized by the Balkan Ethnology Department of the Ethnographic Institute and Museum at the Bulgarian Academy of Sciences and realized as project of the European Commission Jean Monnet Action Program for the support of Study and Research Centers. The book opens a debate on the changing notions of identity in the region of Central and Eastern Europe on the base of analysis of social developments influenced by EU accession and EU integration process. The most important aspect is the analysis of processes of breaking up the borders of national identity and transition towards new forms of transnational identities and emerging of consciosness of All-European unity. The book has a dual focus: on general topics related to the study of national and transnational identities and on the process of European integration. It brings together the work of researchers not only from different parts of Europe (from France to Russia) but from USA and Asia too. This book is a starting point for East-West discussion and brings new knowledge that will be an invaluable contribution to the common European research area.
