The Institute and its scholars are involved in a wide variety of national and international collaborations. Most of these are informal and related to individual research projects. They range from participation in joint conferences, seminars and workshops to co-authorships and co-editorships.
In addition to that, the Institute maintains a number of more formal, institutional co-operations. At a local level, it has a close working relationship with the Faculty of Law, the History Department and the Cluster of Excellence ‘Normative Orders’ at Goethe University Frankfurt. Other partners in the Rhein / Main area include the Academy of Sciences and Literature in Mainz, the Cluster of Excellence ‘Beyond Slavery and Freedom’ at the University of Bonn and the Forschungskolleg Humanwissenschaften in Bad Homburg. At the national level, the Institute co-operates with the more than ten Max Planck Institutes that engage in legal studies. Stefan Vogenauer is chair of the new established network Max Planck Law.
Internationally, the Institute cultivates substantial relationships with universities and research institutes in Argentina, Austria, Australia, Belgium, Brazil, China, Columbia, Denmark, Finland, France, Germany, India, Italy, Japan, Luxembourg, the Netherlands, Peru, Portugal, Spain, Taiwan and the USA. Apart from collaborative events and publications, some of these co-operations involve the joint mentoring and supervision of doctoral students.
With the recent shift of the Institute’s research agenda to selected world regions outside Europe, collaboration with these regions has gained particular importance. At present, therefore, many of the co-operations are with partners in Latin America, East Asia and countries formerly belonging to the British Empire. Research on the history of European Union law is conducted with the support of European institutions, such as the Historical Archives of the European Union, the Court of Justice and the European Commission with its European Union Liaison Committee of Historians.
