The article explores the connections of various forms of nationalism in Argentina with Arab countries and pan-Arabism, focusing on the 1960s. Contrary to much of the existing scholarship on Argentine nationalism, it maintains that nationalist ideas and movements were not necessarily undermined, but instead frequently fortified through transnational exchange. Analyzing how cultural analogies between Argentina and Arab countries were construed on the basis of pre-existing notions of Argentina as a Hispanic country, the article eventually embarks on broader theoretical considerations regarding the advantages and predicaments of transnational history.
