The Roman Republic conquered and occupied territories in the Iberian Peninsula that were previously under the control of native Celtic, Iberian, Celtiberian and Aquitanian tribes and the Carthaginian Empire. The Carthaginian territories in the south and east of the peninsula were conquered in 206 BC during the Second Punic War. Control was gradually extended over most of the peninsula without annexations. It was completed after the end of the Roman Republic (27 BC), by Augustus, the first Roman emperor, who annexed the whole of the peninsula to the Roman Empire in 19 BC.

This conquest started with the Roman acquisition of the former Carthaginian territories in southern Hispania and along the east coast as a result of defeating the Carthaginians (206 BC) during the Second Punic War (218–201 BC), after which the Carthaginian forces left the peninsula. This resulted in an ongoing Roman territorial presence in southern and eastern Hispania. In 197 BC, the Romans established two Roman provinces. These were Hispania Citerior (Nearer Spain) along most of the east coast (an area corresponding to the modern Valencia, Catalonia and part of Aragon) and Hispania Ulterior (Further Spain) in the south, corresponding to modern Andalusia.

Over the next 170 years, the Republic expanded its control over Hispania. This was a gradual process of economic, diplomatic and cultural infiltration and colonization, with campaigns of military suppression when there was native resistance,^[1] rather than the result of a single policy of conquest. The Romans turned some native cities outside their two provinces into tributary cities and established outposts and Roman colonies to expand their control. Administrative arrangements were ad hoc. Governors who were sent to Hispania tended to act independently from the Senate due to the great distance from Rome. In the latter part of this period, the Senate attempted to exercise more control, but this was to try to curb abuse and extortion by officials in the peninsula. Conquest was a process of assimilation of the local tribes into the Roman culture and its economic system and laws.

This changed after the end of the 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 and carried out 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. It was renamed Hispania Tarraconensis. Hispania Ulterior was divided into the provinces of Baetica (most of modern Andalusia) and Lusitania, which covered present day Portugal up to the River Durius (Douro), the present autonomous community of Extremadura^[2] and a small part of the province of Salamanca in today's Spain.
