By 1000 BC, the Celts had occupied the region. In the period of Roman Gaul, Gaulish tribes called Gabalians (Lozère) and Rutènians (Aveyron) occupied the area. Julius Caesar stated that the Gabalians were survivors of the Battle of Alesia. Their capital Anderitum became Javols. The Rutenians, who may have come from the Danube delta and who gave their name to the Rouergue, became allied with Vercingetorix.
