This book explores the influence of right-wing political cultures (including conservatism, political Catholicism, reactionary nationalism and fascism) on nation-building processes and the creation of national identities in modern times. The chapters extend the focus of analysis across the different cultures and movements of the Right, their broad geographical spread, as well as cultural factors. Adopting a transnational perspective, this volume highlights the significance of a series of processes – such as the growth of nationalist imaginaries and political cultures – that extended beyond national boundaries and were often articulated via cross-border dynamics. Special attention is paid to the political cultures and transnational networks of the Right in Europe and Latin America. Case studies including countries such as Spain, France, Italy, Portugal, Brazil and Argentina provide the reader with a broad overview of the circulation of right-wing and conservative thinking. Through an innovative approach, this volume offers scholars, students and the interested reader a valuable historical perspective to understand the development and expansion of right-wing nationalist and authoritarian positions.
