Under the impact of accelerated globalization, transnational integration and international security concerns, the geopolitics of Europe’s borders and border regions has become an area of critical interest. The progressive enlargement of the EU has positioned its borders at the heart of recent discussions on the changing nature of the EU, the meaning of ‘Europe’ and what constitutional shape a more politically unified Europe might take.With enlargement, the EU must elaborate strategies to contend with a fiercely competitive world – and to build fortress-like defences against perceived tensions arising from greater cultural mixing and threats such as terrorism. The authors build up an integral picture of the EU’s internal and external borders and borderlands to reveal the processes of re-bordering and social change currently taking place in Europe. They explore issues such as security, immigration, economic development and changing social and political attitudes, as well as the EU’s relations with the Islamic world and other world powers. The book embraces an array of disciplinary, ideological and theoretical perspectives, offering detailed case studies of different border regions and the concerns of the local inhabitants, while engaging in broader discussions of developments across Europe, state policies and the EU’s relations with neighbouring states.Geopolitics of European Union Enlargement will be of key interest to students and researchers in the fields of European politics, geography, international studies, sociology and anthropology.
