The aim of the course is to understand and to critically assess the functioning, role and significance of the main institutions and actors in the political system of the European Union. Recent political science literature on the political and bureaucratic functioning of the main actors in contemporary EU politics will be discussed. Besides the main institutions (European Commission, Council of the EU, European Parliament, European Council, Court of Justice of the EU), attention will be paid to the interaction between the institutions in the formulation and implementation of EU policies, to interest groups and non-state actors, as well as to the increasing importance of EU-level agencies and national parliaments in EU policy-making.
