Aragonese ( ; in Aragonese) is a Romance language spoken in several dialects by about 12,000 people as of 2011, in the Pyrenees valleys of Aragon, Spain, primarily in the comarcas of Somontano de Barbastro, Jacetania, Alto Gállego, Sobrarbe, and Ribagorza/Ribagorça. It is the only modern language which survived from medieval Navarro-Aragonese in a form distinctly different from Spanish. Historically, people referred to the language as ('talk' or 'speech'). Native Aragonese people usually refer to it by the names of its local dialects such as (from Valle de Hecho) or (from the Benasque Valley). History Aragonese, which developed in portions of the Ebro basin, can be traced back to the High Middle Ages. It spread throughout the Pyrenees to areas where languages similar to modern Basque might have been previously spoken. The Kingdom of Aragon (formed by the counties of Aragon, Sobrarbe and Ribagorza) expanded southward from the mountains, pushing the Moors farther south in the Reconquista and spreading the Aragonese language. The union of the Catalan counties and the Kingdom of Aragon which formed the 12th-century Crown of Aragon did not merge the languages of the two territories; Catalan continued to be spoken in the east and Navarro-Aragonese in the west, with the boundaries blurred by dialectal continuity. The Aragonese Reconquista in the south ended with the cession of Murcia by James I of Aragon to the Kingdom of Castile as dowry for an Aragonese princess. The best-known proponent of the Aragonese language was Johan Ferrandez d'Heredia, the Grand Master of the Knights Hospitaller in Rhodes at the end of the 14th century. He wrote an extensive catalog of works in Aragonese and translated several works from Greek into Aragonese (the first in medieval Europe). The spread of Castilian (Spanish), the Castilian origin of the Trastámara dynasty, and the similarity between Castilian (Spanish) and Aragonese facilitated the recession of the latter. A turning point was the 15th-century coronation of the Castilian Ferdinand I of Aragon, also known as Ferdinand of Antequera. In the early 18th century, after the defeat of the allies of Aragon in the War of the Spanish Succession, Philip V ordered the prohibition of the Aragonese language in the schools and the establishment of Castilian (Spanish) as the only official language in Aragon. This was ordered in the Aragonese Nueva Planta decrees of 1707. In recent times, Aragonese was mostly regarded as a group of rural
