The German Historical Institute Paris (Institut Historique Allemand – IHA) is a central player in research in international history. The Institute is actively involved in the knowledge transfer of the humanities, particularly in the transfer of scientific and socio-political knowledge between France and Germany. It also promotes young researchers by offering a wide range of Franco-German programs. The historians of IHA work on the history of Western Europe – from late antiquity to the present. Cooperation with French and German colleagues allows them to operate in different scientific traditions and transmit the knowledge and methodologies of historical science in both countries. The German Historical Institute Paris pursues its own research projects, organizes scientific events, and is involved in projects and events of its partners. The results are published in its own book collections, in the journal "Francia" or directly online (thanks to scientific blogging or databases). The German Historical Institute Paris plays a pioneering role in promoting the use of new media by humanities researchers. The institute has a multilingual library of over 110,000 books, which is open to the public.
