This volume is the result of an international conference held at Sapienza University in Rome on June 20 and 21, 2013, as the final stage of the PRIN (Progetto di rilevante interesse nazionale) project “Empires and Nations from the 18th to the 20th century”, during which scholars from all over the world – academics, specialists, young researchers, PhD students and post-doctorates – confronted diverse, but connected, topics on the relations between multinational empires and the idea of the nation. In this way, the reality of the historical empires and national states was represented, and concepts such as identity, nationality, and sovereignty analyzed. The first part of this work is dedicated to the analysis of the origins of nation-states in the context of the multinational Habsburg, Ottoman and Tsarist empires, while the second pays particular attention to the issue of national minorities, which followed the dissolution of the great empires. The third part is related to national identity and focuses on art and culture by presenting artists, painters, writers and intellectuals who had played key roles in the formation of their national identities. Such pioneers include Hungarians, Romanians, Serbs, Georgians, Chinese, and Brazilians. Specific sections are dedicated to theoretical approaches and concepts such as imperialism, geopolitics, nationality, and regionalism, and to the analysis of religious and gender issues.
