Is globalization and European integration transforming the basic structure of politics in European nations? Is it eroding basic institutions like national sovereignty, citizenship, social security, and democracy? Is the European Union (EU) a new kind of political institution, differing from a traditional national state? The essays in this volume find that European integration and internationalization has transformed political institutions and styles of governing. However, they argue as well that the U.S. offers important insights into the way EU politics and institutions work.
