Spain's membership of the European Union since 1986 has had a major impact. Driven primarily by political concerns to secure democracy, membership has also served as a catalyst to dynamic economic development in Spain. This book analyzes how the EU has helped shape the political process in Spain, focusing on the key institutions and the policy process. At the same time, Spain's increasingly proactive role within the EU is also explored, with particular attention given to the country's international position in post-Cold War Europe.
