Disintegrating Empire examines the entangled histories of three threads of decolonization: the French welfare state, family migration from Algeria, and the French social workers who mediated between the state and their Algerian clients. After World War II, social work teams, midlevel bureaucrats, and government ministries stitched specialized social services for Algerians into the structure of the midcentury welfare state. Once the Algerian Revolution began in 1954, many successive administrations and eventually two independent states—France and Algeria—continuously tailored welfare to support social aid services for Algerian families migrating across the Mediterranean. Disintegrating Empire reveals the belated collapse of specialized services more than a decade after Algerian independence. The welfare state’s story, Franklin argues, was not one merely of rise and fall but of winnowing services to “deserving” clients. Defunding social services—long associated with the neoliberal turn in the 1980s and beyond—has a much longer history defined by exacting controls on colonial citizens and migrants of newly independent countries. Disintegrating Empire explores the dynamic, conflicting, and often messy nature of these relationships, which show how Algerian family migration prompted by decolonization ultimately exposed the limits of the French welfare state.
