Roman possession of Spanish territory began with the Second Punic War, when Scipio Africanus conquered large parts of it from the Carthaginian enemy.
One of the results of this creation of the province of Hispania Ulterior (Further Spain) in AD 197.
Thereafter the province continued to be gradually enlarged as additional territory was conquered from Spanish tribes.
In 13 BC, as part of Augustus' reforms in the administration of the empire, Hispania Ulterior was divided into the Province of Baetica and Lusitania.
