This text provides an analysis of the enlargement of the European Union and examines from both a theoretical and a political approach issues such as: where does Europe end? should Europe's borders be open or closed? and how does the evolution of territorial politics impact on the course of European integration? The book focuses on the evolving scope and nature of borders in Europe. It discusses how dilemmas of inclusion and exclusion could be handled in the new Europe, how new borders will change the geo-political map and who should be in charge of border policing and administration. It also looks at patterns of migration between current and future EU members, examines ethnic minority problems in the applicant states and analyses the threat of transnational crime across the new borders of the Union. Special attention is devoted to the eastern enlargement of the European Union. This book draws upon such diverse fields as history, sociology, political science and international relations and contains contributions from an international range of respected academics.
