The political geography of Europe and the issues confronting the European Union have changed radically since 1989. Understanding the complex nature - legal, political. linguistic and cultural - of international frontiers in Europe is essential to any serious analysis of contemporary politics and government. Employing a multidisciplinary approach, this volume discusses several central issues, including: progress towards a European identity and changes in political identities within the EU; the extent to which the internal frontiers have become different in kind from the external frontiers; and the varying ways in which frontier issues are posed in different parts of the Union. This volume analyzes the consequences of dismantling controls at the internal frontiers and of measures to harden the external frontier.
