<!--With Lusitania ( and [[Asturia]] and [[Gallaecia]]), Rome had completed the conquest of the [[ Iberian peninsula]], which was then divided by Augustus (25-20 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, while on its eastern side its border passed through ''Salmantica'' and ''Caesarobriga'' to the ''Anas'' ([[Guadiana]]) river.

The capital of Lusitania was ''Augusta Emerita'' (currently [[Mérida, Spain|Mérida]]) in Spain. Modern [[Coimbra]], was the Roman city of [[Aeminium]], and near modern [[Condeixa-a-Nova]], was the Roman city of [[Conímbriga]]. Conímbriga was not the largest city of Lusitania, but it is the best preserved. Built on a long-inhabited site, it was sacked by the [[Suevi]] in 468, and its inhabitants fled to [[Aeminium]], which inherited its name and is nowadays known as Coimbra. Conimbriga's city walls are largely intact, and the mosaic floors (''illustration, right'') and foundations of many houses and public buildings remain. In the baths, visitors can view the network of stone heating ducts (the ''hypocaust'') beneath the now-missing floors. Archaeologists estimate that, though excavations began in 1898, only 10 percent of the city has been excavated.-->
Di bawah [[Diocletianus]], Lusitania mempertahankan perbatasannya dan dipimpin oleh seorang ''praeses'', belakangan oleh seorang ''consularis''; akhirnya, dipersatukan dengan provinsi-provinsi lainnya untuk membentuk ''Diocesis Hispaniarum'' ("[[Diosis]] Hispania").
