Catalonia is an autonomous community of Spain, designated as a nationality by its Statute of Autonomy. Most of its territory lies on the northeast of the Iberian Peninsula, to the south of the Pyrenees mountain range. Catalonia is administratively divided into four provinces or eight regions, which are in turn divided into 42 comarques. The capital and largest city, Barcelona, is the second-most populated municipality in Spain and the fifth-most populous urban area in the European Union.

Catalan, known in the Valencian Community and Carche as Valencian, is a Western Romance language. It is the official language of Andorra, and an official language of three autonomous communities in eastern Spain: Catalonia, the Balearic Islands and the Valencian Community, where it is called Valencian. It has semi-official status in the Italian comune of Alghero, and it is spoken in the Pyrénées-Orientales department of France and in two further areas in eastern Spain: the eastern strip of Aragon and the Carche area in the Region of Murcia. The Catalan-speaking territories are often called the Països Catalans or "Catalan Countries".
