There are numerous examples of how religion and nationalism intertwine. In some cases, a common religion is the fundamental marker of a nation's identity, whereas in others secular nationalism tries to hold together people of different religious beliefs. This book examines the link between religion and nationalism in contemporary polities. By exploring case studies on India, Russia, Israel, Canada, Chechnya, Bosnia-Herzegovina, Belgium, Northern Ireland, Scotland, Sri Lanka, Catalonia and the Basque Country, it seeks to understand the relationship between these two key societal forms of diversity and assess the interaction between religious and nationalist perspectives. Expert contributors examine a variety of phenomena, including secular nationalism, secessionism, and polities in which religious pluralism is evolving. This book will be of interest to students and scholars of political science, religion and politics, nationalism, federalism, secession, political philosophy, racial and ethnic politics and comparative politics.
