The Battle of Perugia was fought in the winter of 41 BC and 40 BC between Octavian and Lucius Antonius, the brother of Mark Antony, who was aided by Antony's wife, Fulvia. Octavian's forces were victorious, obtaining the surrender of Perugia. Fulvia was exiled, and died of illness while in exile. This left Antony free to marry Octavian's sister, and a temporary peace between Octavian and Antony resulted.
