Languages of Catalonia
There are four languages with official status in Catalonia (an autonomous community of Spain): Catalan; Spanish- which is official throughout Spain; Aranese, a dialect of Occitan spoken in the Aran Valley; and Catalan Sign Language. Many other languages are spoken in Catalonia as a result of recent immigration from all over the world.
Northern Catalonia
Northern Catalonia ( , also known as "Catalunya Nord" ), French Catalonia or Roussillon refers to the Catalan-speaking and Catalan-culture territory ceded to France by Spain through the signing of the Treaty of the Pyrenees in 1659 in exchange of France's effective renunciation on the formal protection given to the recent founded Catalan Republic. The area corresponds exactly to the modern French "département" of the Pyrénées-Orientales which were historically part of Catalonia since the old County of Barcelona, and lasted during the times of the Crown of Aragon and the Principality of Catalonia until they were given to France by Spain.
