The Basque people have preserved their ethnic identity and sense of themselves as a separate community despite centuries of repression, diaspora, and economic and social upheaval—one of the most remarkable achievements in the history of the phenomenon we call nationalism. In The Social Roots of Basque Nationalism, sociologist Alfonso Pérez-Agote addresses the social mechanisms that Basques employed to sustain their ethnic identity under the Franco Regime and demonstrates how persecution actually encouraged the extension of Basque nationalist consciousness. He also reveals how state political pressure radicalized one element of the Basque-nationalist movement, resulting in the formation of ETA, an armed terrorist wing that itself became a mechanism for extending nationalist consciousness. Finally, he examines the subsequent changes in Basque nationalism following Franco’s death and the extension of democracy in Spain, which resulted in the institutionalization of the movement into an autonomous political power.
