Hispania was the Roman name for the Iberian Peninsula. Under the Republic, Hispania was divided into two provinces: Hispania Citerior and Hispania Ulterior. During the Principate, Hispania Ulterior was divided into two new provinces, Baetica and Lusitania, while Hispania Citerior was renamed Tarraconensis. Subsequently, the western part of Tarraconensis was split off, first as Hispania Nova, later renamed Callaecia
