explores the interaction between religion, nationalism, and political modernity in the first half of the 20th century, taking the case of the Serbian Orthodox Church as an example. This book historicizes the widely held assumption that the bond between religion and nationalism in the Balkans is a natural one or that this bond has been historically inevitable. It tells a complex story of how East Orthodox Christianity came to be at the core of one version of Serbian nationalism by bringing together the themes of religion, nationalism, politics, state-building, secularization, and modernity. Maria Falina reconstructs how the ideological fusion between Serbian nationalism and East Orthodox Christianity was forged. The analysis emphasizes ideas and ideologies through a close reading of public discourses and historical narratives while paying attention to individual actors and their personal histories. The book argues that the particular political vision of the Serbian Orthodox Church emerged in reaction to and in interaction with the challenges posed by political modernity that were not unique to Yugoslavia. These included establishing the modern multinational and multi-religious state, the fear of secularization, and the rise of communism and fascism. makes an important contribution to understanding the history of interwar Yugoslavia, 20th-century Europe, and the ties between religion and nationalism.
