In 121 BCE,[1] Bituitus was defeated by the Roman general Fabius Maximus, ending the power of the Arverni in Mediterranean Gaul, or present-day southern France.
In 121 BC, the Roman proconsul Domitius Ahenobarbus undertook a war against the Allobroges, who allied with the Arverni under Bituitus.
[2] Following his defeat, Bituitus was taken prisoner and sent to Rome, where he was sentenced by the senate to exile in Alba Fucens, one of three foreign kings known to have been held there.
From the plunder of the Auvergne, Fabius erected his victory arch, the Fornix Fabianus along the Via Sacra, and adorned it with a statue of himself.
[5] Bituitus is the last known king of the Arverni, and later sources, such as Julius Caesar's war commentaries, indicate that they were afterwards ruled by an oligarchy or council analogous to the Roman senate.
