On 1 May 2000 the Staatsarchief ['state archive'] moved to the IISH. The Staatsarchief originated in Amsterdam's Staatsliedenbuurt and became the archive of the squatters' and activists' movements in the Netherlands. As the creative spirit behind the archive, Eric Duivenvoorden started gathering material about squatting in his own neighbourhood the Staatsliedenbuurt in the early 1990's.
Driven by enthusiasm and historical awareness, he added material from other squatters' movements in and outside Amsterdam to the archive.
The archive contains collections of archival documents (minutes, appointment and personal diaries, pamphlets, reports), periodicals, posters, photographs, audiovisual materials, garments and objects. The material is accessible via an inventory and comprises sections on Amsterdam's squatters' movement, neighbourhood archives in Amsterdam, squatted buildings in Amsterdam, the Dutch squatters' movement, various actions (not related to the squatters' movement) and squatters' and activists' movements in other countries.
The material, which Eric Duivenvoorden used in his book Een voet tussen de deur. Geschiedenis van de kraakbeweging 1964-1999 ['Foot in the door. History of the squatters' movement'], contains a wealth of information about the transition of the squatters' movement from a regular movement for housing for young adults into an oppositional movement, with squatted buildings as experiments in residential and occupational forms and lifestyles.
The arrival of the Staatsarchief makes the IISH the most important source in the Netherlands of material on the squatters' movement.
