Drawing on case studies and interviews from Croatia, Hungary, and Turkey, the book investigates how the past has been exploited to serve the interests of nationalism in the twenty-first century, and how museums themselves are exploited to serve nationalist ideologies. Arguing that museums have become the cultural offshoots of political wars, Posocco demonstrates that they are now places where the national past is contested, rewritten, sometimes even created from scratch, and finally exhibited. The book also examines the micro-sociological and political aspects, which will be the foundation for further reflections on the macro dynamics of museum-making in other countries and contexts. It provides rare and interesting insights into how museums materialise culture in the service of nationalism. The book will be of interest to those engaged in the study of museums, heritage, nationalism, memory and politics, as a result.
