This books explores the rise of civilizational populism throughout the world, and its consequences. Civilizational populism posits that democracy ought to be based upon enacting the 'people's will', yet it adds a new and troubling dimension to populism's thin ideology: a civilization based classification of peoples and division of society. Today, we increasingly find not conflict between civilizations, but conflict within states over their civilizational identity. From Western Europe to Turkey, and from India and Pakistan to Indonesia, populists are increasingly employing a civilization based classification of peoples in order to define the identities of 'the people' and their perceived enemies. This book is the first to examine civilizational populism as global phenomenon rather than a uniquely Western form of politics. Through a series of case studies, the book examines the role played by religion in forming civilizational identities, but also investigates the often deleterious consequences of civilizational populism entering the political mainstream.
