On 25 November 1935, the charter of foundation of the International Institute for Social History was signed.

The IISH was founded by Prof Posthumus, husband of Willemijn Posthumus-van der Goot, one of the founders of the IAV. Both institutes started on the premises of Keizersgracht 264. The IISH made two rooms available for the sister organisation IAV.
