About the Historical Archives

"The common European memory is best captured and preserved in the Historical Archives of the European Union, where documents of the Institutions of the European Union are kept along with the papers of pioneers and visionaries, of political leaders, and of the numerous European voices from movements, associations and political groups."

Dieter Schlenker, Director of the Historical Archives of the European Union

Our Mission


Preserve and make accessible for research the archives deposited by EU institutions according to the thirty-year rule governing access to archival material, collect and preserve private papers of individuals, movements and international organizations involved in European integration, facilitate research on the history of the European Union, promote public interest in European integration and enhance transparency in the functioning of EU Institutions.


The HAEU was established in 1983 following the regulation by the Council of the European Communities and the decision by the Commission of the European Communities to open their historical archives to the public. A subsequent agreement in 1984 between the European Commission and the European University Institute (EUI) laid the groundwork for establishing the Archives in Florence, and the HAEU opened its doors to researchers and the public in 1986. Since then, a 2011 Framework Partnership Agreement between the EUI and the European Commission reinforced the Historical Archives’ role in preserving and providing access to the archival holdings of the EU Institutions. In March 2015 the Council of the European Union amended the regulations from 1983 by adopting a new Council Regulation. Subsequently, on 15 April 2015 a new Framework Partnership Agreement between the EUI and the European Commission was signed, setting the frame for an enhanced cooperation and partnership between the HAEU and the EU Institutions.

A third Framework Partnership Agreement was signed between the EUI and the European Commission in 2019.
