Roger Caillois
In 1937, Leiris teamed up with Bataille and Roger Caillois to found the Collège de sociologie in response to the current international situation. Increasingly involved in politics, he took part in a mission to Côte d'Ivoire in the French colonies, in 1945. As a member of Jean-Paul Sartre's editorial committee for "Les Temps modernes", Leiris was involved in a series of political struggles, including the Algerian War, and was one of the first to sign the Déclaration sur le droit à l'insoumission dans la guerre d'Algérie, the 1960 manifesto supporting the fight against the colonial forces in Algeria.
