European integration has had a profound impact on the politics of Southern Europe, a region that was initially at the margin of the decision-making processes of the European Union, but is gradually becoming more and more influential. This volume offers a comparative overview of modern politics in Spain, Portugal, Italy, and Greece, focusing in particular on the process of integration of these countries into the European Union and on the impact of European public policy. The author analyzes the development of Southern European political systems, from the establishment of democratic governments to the most recent political events, looking at each individual system and finding patterns, similarities of development, as well as differences between them. Among the topics examined are the building of institutions, the parties and party systems, foreign policies, the political culture of each country, and the recent efforts towards the creation of a space of security and peace in the Mediterranean.
