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

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 joint declaration by European Commission President Romano Prodi and EUI President Yves Meny on 27 September 2004 and a series of Framework Partnership Agreements since 2011 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 Archives Regulation 354 of 1983 by adopting a new Council Regulation. The most recent Framework Partnership Agreement was signed on 17 March 2023, setting the strategic frame for enhanced cooperation and partnership between the HAEU and the EU Institutions for a period of five years.
