State secrets and a handwritten page by Marx: a look inside the IISG treasury

The International Institute of Social History in Amsterdam preserves a vast collection of archives documenting global social and labor movements, including rare items like the original handwritten page of the Communist Manifesto. Retiring director Leo Lucassen and his successor Lily Knibbeler highlight the institution's role in protecting sensitive historical materials and ensuring that the stories of marginalized groups and movements are preserved for future generations.
