History of the territorial organization of Spain

The history of the territorial organization of Spain, in the modern sense, is a process that began in the 16th century with the dynastic union of the Crown of Aragon and the Crown of Castile, the conquest of the Kingdom of Granada and later the Kingdom of Navarre. However, it is important to clarify the origin of the toponym Spain, as well as the territorial divisions that existed previously in the current Spanish territory.
