Book excerpt: A Transnational History of Right-Wing Terrorism offers new insights into the history of right-wing extremism and violence in Europe, East and West, from 1900 until the present day. It is the first book to take such a broad historical approach to the topic. The book explores the transnational dimension of right-wing terrorism; networks of right-wing extremists across borders, including in exile; the trading of arms; the connection between right-wing terrorism and other forms of far-right political violence; as well as the role of supportive elements among fellow travelers, the state security apparatus, and political elites. It also examines various forms of organizational and ideological interconnectedness and what inspires right-wing terrorism. In addition to several empirical chapters on prewar extreme-right political violence, the book features extensive coverage of postwar right-wing terrorism including the recent resurgence in attacks. This book will be of great interest to students and scholars of right-wing extremism, fascism, Nazism, terrorism, and political violence.
