A Roman exile and supporter of Marius, turned military leader.
When Sulla put out his proscription lists, Domitius, who was married to Cinna’s daughter, was forced to flee to Africa. Pompey had been ordered to engage with Domitius because Domitius had assembled an extremely large force, crossed from Africa into Italy, and had become a tyrant rather than an exile. Their forces fought at Utica. Pompey won. Plutarch reports that only three thousand out of twenty thousand escaped (Plutarch, Pompey 12). According to some accounts, Domitius was executed after the battle.
