This article traces how Paris became a key center of international solidarity with Argentina’s disappeared during the dictatorship. It follows exiled activists like Liliana Andreone, French theater groups such as Théâtre du Soleil, and human rights organizations like AIDA, which used art, performance, and public protest to expose Argentina’s “dirty war” and demand accountability. French intellectuals, artists, and ordinary citizens joined Argentinian exiles to boycott the 1978 World Cup, support the Madres de Plaza de Mayo, and stage powerful visual actions like the 1981 banner march through Paris. The piece shows how France’s own memory of occupation and resistance shaped this solidarity and argues that remembering these transnational networks is crucial for confronting today’s authoritarian threats and attacks on culture.
