Geographical, historical, and political factors cause differences between Spanish regions or provinces of Spain.
Modern Spain appeared as a result of the wake of the expansion (Reconquista) of the Christian lands in northern Spain.
After the reconquest, the process of religious and linguistic unification and political centralization followed.
The contemporary division of Spain into Autonomous Communities is an effort to admit nationalities and regional identities in Spain.
After the Reconquista, depending on the duration of the Muslim occupation, some territories became identified themselves as distinct from the rest of Spain – Galicia, León, Cantabria, Asturias, the Basque Country, Navarre, Aragon, Catalonia, Balearic Islands, Valencia, Andalusia.
Catalonia is a unique province in Spain. This province even has its own customs.
