This article explores the vitally important yet often neglected role of medicine and health care in the conduct of the Algerian War of Independence (1954–62). Using French, Swiss, and recently opened Algerian archival materials, it demonstrates how Algerian nationalists developed a health-service infrastructure that targeted the domestic and international arenas. It argues that they employed the powerful language of health and healing to legitimize their claims for national sovereignty and used medical organizations to win local support, obtain financial and material aid from abroad, and recast themselves as humanitarians to an increasingly sympathetic international audience. This research aims to situate Algerian efforts into a broader history of decolonization and humanitarianism and contributes to rethinking the process through which political claims were made at the end of empire.
