This article examines the organisation of Iranian student opposition at the Cité Internationale Universitaire de Paris (CIUP) between the late 1940s and 1970s against a backdrop of the hardening of the Iranian regime from 1953 onwards and increasing student demands in France. It draws on sources from the CIUP, interviews with former residents, and the archives of the Renseignements généraux (French General Intelligence Division), responsible for informing the government about political movements and organisations likely to threaten state security. The unique setting of CIUP provided students with opportunities for socialization and political structuring, enabling them to establish themselves as an opposition force. Meanwhile, struggles around the Maison de l’Iran in particular led the CIUP to become the subject of demands. The article begins by presenting the establishment of the Association des Étudiants Iraniens en France (Iranian Students Association in France) at the CIUP in the early 1950s. It then focuses on the Maison de l’Iran as a place of tension and confrontation between students and the Iranian authorities. Finally, it explores how activists shifted their strategies after the Maison closed in 1972, mainly by forging closer ties with other national communities.
