This course examines the origins and development of European integration since the turn of the 20th century. The first section of the course considers the antecedents of integration before 1914 and in the Interwar period. It provides a comparative basis for the second part, which focuses on the decade between the Marshall Plan and the Treaties of Rome. The final part of the course deals with the European Communities from their foundation until the Treaty of Maastricht and the evolution and role of the European Union law and institutions in the European Integration process. Through examining the key moments in the political and institutional development of European integration, students will gain a comprehensive and systematic understanding of the history of the EU and better insight into contemporary political and economic relations in Europe, the EU legal system and the process of decision making in the European Union.
