"Hispania" was divided into two provinces: Hispania Citerior and Hispania Ulterior. In 27 B.C, Hispania Ulterior was divided into two new provinces, Hispania Baetica and Hispania Lusitania, while Hispania Citerior was renamed Hispania Tarraconensis. This division of Hispania explains the usage of the singular and plural forms (Spain, and The Spains) used to refer to the peninsula and its kingdoms in the Middle Ages.
