The Crown of Aragon was a personal and dynastic union of the country of Barcelona and the Kingdom of Aragon.
The Crown of Aragon (Aragonese: Corona d'Aragon, Catalan: Corona d'Arago, Latin: Corona Aragonum, Spanish: Corona de Aragon) was a personal and dynastic union of the county of Barcelona and the Kingdom of Aragon. At the height of its power in the 14th and 15th centuries, the Crown of Aragon was a thalassocracy (a state with primarily maritime realms) controlling a large portion of the present-day eastern Spain and southwestern France, as well as some of the major islands and mainland possessions stretching across the Mediterranean as far as Greece. The component realms of the Crown were not united politically except at the level of the king, who ruled over each autonomous polity according to its own laws, raising funds under each tax structure, dealing separately with each cortes. Put in contemporary terms, the disparate lands of Aragon functioned more as a confederacy of cultures rather than as a single country.
