The Center for European Integration Studies (Zentrum für Europäische Integrationsforschung, ZEI) is an interdisciplinary research and post-graduate education institute at the University of Bonn, Germany, based in its Faculty of Arts and the Faculty of Law. ZEI has participated in research, policy advice, and dialogue between science and practice since its establishment in 1995. ZEI also offers graduate education and mid-career training opportunities to contribute to the resolution of unresolved issues of European integration and the shaping of Europe's global role. ZEI directors are Prof. Dr. Ludger Kühnhardt and Prof. Dr. Christian Koenig.
The Berlin-Bonn Act of May 29, 1994–dealing with the consequence of the move of Germany’s national political institutions from Bonn to Berlin - provided for the establishment of a "Center for European Integration Studies” (ZEI) and a "Center for Development Research” (ZEF) as central scientific institutions of the University of Bonn. On May 4, 1995 the Senate of the University of Bonn agreed to establish these two centers. The overall concept was formulated in consultation with the participating organs of the federal government and the state of North Rhine-Westphalia. It is based on an original proposal of the Senate of the University of Bonn from February 11, 1993. The Senate decision of May 4, 1995 is considered the founding date of the "Center for European Integration Studies" (ZEI) and the "Center for Development Research." (ZEF)
According to the founding resolution of the Senate of the University of Bonn of May 4, 1995, the tasks of ZEI are as follows: "ZEI will function as a multidisciplinary and interdisciplinary institution aimed working on problems in the areas of political, legal, economic, social and cultural integration disparities in a regional and pan-European context. ZEI will conduct basic research in the conceptual area that encourages integration of research and to coordinate these efforts within the University and externally. ZEI is to take part in the solutions of concrete problems of integration by offering practical advice. All in all ZEI sees itself as a platform for the discussion of policy issues, a place to develop concepts, hypotheses and models. As an interface between theory and practice, ZEI focuses on institutional- and capacity-building in the field of integration research in Europe. ZEI can only realize its aforementioned goals through consistent openness to the public, through inclusion of guest researchers and through close cooperation with non-university institutions to integrate research, practice and integration of the European Union.”
