Internationaal Instituut voor Sociale Geschiedenis
- International Institute of Social History
- IISG, IISH
The International Institute of Social History (IISH) was officially established on November 25, 1935, but its history dates back to the 1920s. In 1914, Nicolaas W. Posthumus (1880-1960), who ranked among the pioneers of modern economic history in the Netherlands had set up the Netherlands Economic History Archive (NEHA), the first of a series of scholarly institutions he initiated. The NEHA concentrated on the preservation of archives of companies and related organisations, and on the collection of other sources relevant to economic history. Since Posthumus was a collector with a broad vision, he included materials from individuals and organisations in the Dutch labour movement.
Since 1979 the IISH has been an institute of the Royal Netherlands Academy of Arts and Sciences (KNAW).
Personal archives at the IISH are (among many others) the collections of the papers of Diego Abad de Santillán, Alexander Atabekian, Angelica Balabanoff, Bernt Carlsson, Ruth Fischer, Emma Goldman, Rudolf Hilferding, Karl Kautsky, Gustav Landauer, Arthur Lehning, Max Nettlau, Theodor Liebknecht, Toma Sik and Leon Trotsky.
There are also many institutional archives, among which the archives of the Russian Socialist Revolutionary Party, the Red Army Faction and the International Confederation of Free Trade Unions. Moreover, in the last decades the institute acquired the archives of Greenpeace and Amnesty International.
