However, his younger brother Dumnorix was a leader of the tribe’s anti-Roman faction; who “...thought it better to be dominated by their fellow Gauls... rather than the Romans.”.

In 63 BC, Diviciacus survived the Battle of Magetobriga, where forces of the Sequani and Arverni, together with Germanic troops under the Suebi king Ariovistus, massacred the Aedui.

Throughout the Gallic Wars Dumnorix was able to actively sabotage Caesar's conquests many times thanks to his powerful position among the Aedui.

Delamarre contends that, in addition to holding the religious office of druid, Diviciacus may have been the Uergobretos, the annually elected political leader or chief magistrate[8] of the Aedui, one of the most powerful nations in Gaul.

[10] Diviciacus appears as a special Druid unit in the 2003 video game Praetorians, part of which is set during the Gallic Wars.

The lyrics to the Eluveitie song "(Do)minion" are written from the point of view of Diviciacus, addressed to his brother Dumnorix.
