The IISH is a unique institute, serving science and society on a global scale. At an international level, we generate and offer reliable information and insights about the (long-term) origins, effects and consequences of social inequality.
To promote this, we form an international hub for social historians worldwide. We offer and produce historical sources and data, facilitate social-history research and collaborate internationally in ground breaking research projects.
Moreover, by preserving the heritage of often oppressed social movements, the Institute serves the quality of the world's memory. With our work we hope to contribute to a vibrant civil society.
Established in 1935, the IISH is one of the world's leading research institutes on social history. Since 1979 the IISH has been an institute of the Royal Netherlands Academy of Arts and Sciences (KNAW). The collections, some of which concern politically sensitive materials, are the property of or have been issued on standing loan to the independent IISH Foundation.
