Other territories in the former Crown of Castile are left out for different reasons. The territory of the Castilian Crown actually comprised all other autonomous communities within Spain with the exception of Aragon, Balearic Islands, Valencia and Catalonia, all belonging to the former Crown of Aragon, and Navarre, offshoot of the older Kingdom of the same name. Castile was divided between Old Castile in the north, so called because it was where the Kingdom of Castile was founded, and New Castile, called the Kingdom of Toledo in the Middle Ages. The Leonese region, part of the Crown of Castile from 1230, was from medieval times considered a region in its own right on a par with the two Castiles, and appeared on maps alongside Old Castile until the two joined as one region - Castile and Leon - in the 1980s. In 1833, Spain was further subdivided into administrative provinces.
