In 52 BC, during the Gallic Wars, the Arvenian chief Vercingetorix led the Gallic revolt against the armies of Caesar. After an initial victory at the Battle of Gergovia, Vercingetorix was defeated by the Romans at the Battle of Alesia, after which the Arverni lost their power of suzerainty. They maintained however a status of "civitas libera", and remained a prosperous tribe after the Romanization. Under emperor Augustus, their capital was moved to Augustonemetum (present-day Clermont-Ferrand).
