The Aquitani were a tribe that lived in the region between the Pyrenees, the Atlantic Ocean, and the Garonne, in present-day southwestern France[1] in the 1st century BC. The Romans dubbed this region Gallia Aquitania. Classical authors such as Julius Caesar and Strabo clearly distinguish the Aquitani from the other peoples of Gaul, and note their similarity to others in the Iberian Peninsula.
Their old language, the Aquitanian language, was a precursor of the Basque language[2] and the substrate for the Gascon language (one of the Romance languages) spoken in Gascony. Between the 1st century and the 13th century, the Aquitani gradually adopted the Gascon language while part of the Roman Empire, then the Duchy of Gascony and the Duchy of Aquitaine.
