Iberian languageThe Iberian language was the language of an indigenous western European people identified by Greek and Roman sources who lived in the eastern and southeastern regions of the Iberian Peninsula in the pre-Migration Era (before about 375 AD). An ancient Iberian culture can be identified as existing between the 7th and 1st centuries BC, at least. Iberian, like all the other Paleohispanic languages except Basque, was extinct by the 1st to 2nd centuries AD. It had been replaced gradually by Latin, following the Roman conquest of the Iberian Peninsula.
