This encyclopedia offers the most comprehensive and up-to-date resource on the European integration process. Under the editorial directorship of Finn Laursen and associate editors Derek Beach, Roberto Domínguez, Sung-Hoon Park, Sophie Vanhoonacker, and Amy Verdun, the publication brings together peer-reviewed contributions by leading researchers on the European Union as a global actor. Topics include the basic treaties, institutions, and policies of the European Union and the previous European Communities, the European Coal and Steel Community, the European Economic Community, and the European Atomic Energy Community. It also includes articles on the various conceptual frameworks and theories that have been developed by political scientists to guide research into the integration process and the policy- and decision-making processes with a focus on the roles of the different institutions, the European Council, the European Commission, the European Parliament, and the Court of Justice of the EU. Additionally, the publication includes articles on the member states as well as external relations and foreign policies of the EU. As a result, the Oxford Encyclopedia of European Union Politics is a vital resource for students, scholars, and policymakers.
