This book provides a genealogy of radical Basque nationalism and the means by which this complex, often violent, political movement has reinforced Basque identity. Radical nationalists are mobilized by a shared frame of reference where ethnicity and violence are intertwined in a nostalgic recreation of a golden age and a quasi-religious imperative to restore that distant past. Muro critically examines the origins of the ethno-nationalist conflict and provides a comprehensive examination of Euskadi Ta Askatusana’s (ETA) violent campaign. The book analyzes the interplay of ethnicity and violence and stresses the role of inherited myths, memories, and cultural symbols to explain the ability of radical Basque nationalism to endure.
