Lusitania shares border with Hispania Tarraconensis
Roman province
Division under Augustus (25–20 BC)
With Lusitania (and Asturia and Gallaecia), Rome had completed the conquest of the Iberian peninsula, which was then divided by Augustus (25–20 BC or 16-13 BC) into the eastern and northern Hispania Tarraconensis, the southwestern Hispania Baetica and the western Provincia Lusitana. Originally, Lusitania included the territories of Asturia and Gallaecia, but these were later ceded to the jurisdiction of the new Provincia Tarraconensis and the former remained as Provincia Lusitania et Vettones. Its northern border was along the Douro river, while on its eastern side its border passed through Salmantica (Salamanca) and Caesarobriga (Talavera de la Reina) to the Anas (Guadiana) river.
Between 28 and 24 BC Augustus' military campaigns pacified all Hispania under Roman rule, with the foundation of Roman cities like Asturica Augusta (Astorga) and Bracara Augusta (Braga) to the north, and to the south Emerita Augusta (Mérida) (settled with the emeriti of the Legio V Alaudae and Legio X Gemina legions).
Between the time of Augustus and Claudius, the province was divided into three conventus iuridicus, territorial units presided by capital cities with a court of justice and joint Roman/indigenous people assemblies (conventus), that counseled the Governor:
