Abstract: In 1924, the Italian ship Regia Nave Italia visited twenty-eight ports in thirteen Latin American states. Initially conceived as a commercial venture, it became a tool of Mussolini’s foreign policy led by Giovanni Giurati, a cabinet minister appointed as extraordinary ambassador.This article uncovers the colonial agenda of this voyage, arguing that a racialised vision of the Italian diaspora in Latin America shaped strategic alignments between the fascist government and Italian economic elites. It shows how ideas of race, migration, and Latinity configured discursive strategies designed to materialise fascism’s project of demographic imperialism through engagement with local authorities and their population policies. Within a longer genealogy of colonial practice, the Regia Nave Italia illustrates how Italy’s informal empire intersected with fascist ambitions across the Atlantic.
