This volume analyzes the historical continuities and transformations of fascist movements across Ibero-America, Europe, and the United States from the twentieth century to the twenty-first century. By examining political ideologies, networks, and transnational influences, the chapters explore how authoritarian and right-wing populist movements have evolved, adapted, and interacted in different historical contexts. The book provides a comparative perspective on the intersections of fascism, corporatism, Catholicism, nationalism, and contemporary radical right movements, shedding light on their impact on democratic institutions, foreign policy, and social structures. Fascist Legacies and the New Right Across the Atlantic will be beneficial for scholars, researchers, and postgraduate students interested in the history of fascism, populism, and right-wing movements in Ibero-America, Europe, and the United States.
