ABSTRACT
The political behaviour of élites and citizens, the party system, and the standards of governability in Spain cannot be understood without adequate attention to the splits of identity between citizens and territories in that country. The Basque case is the most critical of those splits, because the relationship between the national government and the Basque region reflects a cleavage of the first order in Spanish politics. The present study of Basque polarized pluralism includes political attitudes, ethnic identity, and the support of terrorism.
