Between 125 and 122 BC, the armies of the Roman Republic crossed the Alps and fought the Salluvii and Vocontii. After the Allobroges gave shelter to the Salluvian chiefs and raided the Aedui, a recent ally of Rome, the latter declared war against them. In 121 BC, the Roman forces defeated the Allobroges at the Battle of Vindalium, which took took place near Vindalium, a Cavarian settlement probably corresponding to Mourre-de-Sève (Sorgues). In the aftermath of a decisive Gallic defeat at the Battle of the Isère River in August of the same year, the territory of the Cavari was integrated into the province of Gallia Transalpina some time between 120 and 117 BC. During the Cimbrian War, the Battle of Arausio took place near their hill-fort in October 105 BC.
