What modern country did the Romans refer to as Hispania?

The Romans referred to the region known today as Spain as Hispania. This designation began during the Roman Republic and continued into the Roman Empire. Hispania encompassed a variety of territories, including parts of what is now Portugal and the entire Iberian Peninsula, which was divided into various provinces such as Hispania Citerior and Hispania Ulterior. While modern-day Portugal was indeed part of the Roman province, the term Hispania primarily denotes the larger territory that corresponds closely to contemporary Spain. Consequently, the connection between Hispania and Spain is direct and well-documented in historical texts.
