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 areas; Catalan continued to be spoken in the east and Navarro-Aragonese in the west. The Aragonese Reconquista in the south ended when James I of Aragon gave Murcia to the Kingdom of Castile as dowry for an Aragonese princess.
