 This changed after the end of the Roman Republic and the establishment of rule by emperors in Rome.After the Roman victory in the Cantabrian Wars in the north of the peninsula (the last rebellion against the Romans in Hispania), Augustus conquered the north of Hispania, annexed the whole peninsula to the Roman Empire and carried out an administrative reorganisation in 19 BC.The Roman province of Hispania Citerior was significantly expanded and came to include the eastern part of central Hispania and northern Hispania.
