The main objective of WU's Europainstitut is to actively support European integration as a way to promote prosperity for all Europeans based on the principles of freedom, democracy, equality, and the rule of law. Top quality research and teaching in the field of European integration are needed to reach this goal. The Institute’s research is aimed primarily at scholars, students, policy makers in the fields of government, administration and the economy, and the interested public.
The Europainstitut started its activities in February 1990 under Univ.-Prof. Dr. Stefan Griller (Lehrstuhl für Öffentliches Recht unter besonderer Berücksichtigung des Europarechts). In Summer 1993 two additional institutes joined the Europainstitut: European Economics under Univ.-Prof. Dr. Fritz Breuss and Business Administration with special focus on European Integration under Univ.-Prof. Dr. Gerhard Fink.
In 1998 the European Commission awarded the title Jean Monnet Centre of Excellence to the Europainstitut, which earned reputation as an international centre of competence.
After the coming into force of the new university law (UG 2002) the institue was named "Europainstitut" as of 1.1.2004.
On January 1, 2012 the Institute for European and International Law and the Institute for International Economcs have been founded as successors of the Europainstitut. The Europainstitut has been transfered into a research institute (as in §20 of the WU Satzung).
