Spain is a country known for its cultural diversity, with many national sensibilities that are constantly clashing and counter-balancing each other. There are three strong national sensibilities within the Spanish state that historically have developed a strong national spirit which are constantly in tension. These are Castilla, the Basque Country and Catalonia. For historical reasons, Castilla was to be the dominant sensibility that produced the national spirit of Spain. Catalan and Basque nationalisms were subordinated to Castilla, resulting in a clash between the strong homogenizing and centralized quality of Spanish nationalism with Catalan and Basque identity.
