The introduction to the European Integration is an integral part of the system of teaching foreign students on a Master's degree program and is one of the compulsory optional subjects. As this is a very complex and comprehensive system, we have decided in a simplified way to define the basic areas of European integration. We have tried to focus mainly on the historical background and development of European integration, the theory of European integration, the common foreign and security policy, the institutional system of the European Union and the legal regulation and the basic principles of the EU internal market.
