Iberian Penisula 1270-1494 Autonomous Communities of Spain Today
The official language in Spain is Castilian (as known as Spanish) and all the Spaniards have the duty to know it and the right to use it.
It is also the most widely spoken Romance language, an expressive instrument for a community that embraces the globe, spoken by people from many different ethnic backgrounds.
The name of Castilian, and later on Spanish, really emerges from the re-conquest of Spain from the Moors by the Christians and it became the bridge of communication between the different peoples of the Iberian peninsula.
The Real Academia Española, located in Madrid, is entrusted with "purifying, clarifying and giving splendour" to the language, in close contact with other Latin American academies, and mitigating the problems arising from the use of a language spoken in such a large geographic expanse. Its members are recruited from among the most prestigious literary creators and academics.
