Like both of his brothers, Gaius started his life free from paternal guidance, in the midst of scandals, parties and gambling.
Led by centurion Titus Pullo, the men refused to fight, and turned traitors.
In 44 BC, Gaius was an urban praetor, while his brothers Mark Antony and Lucius Antonius were consul and tribune, respectively.
After the assassination of Caesar, Gaius (as a Caesarean) was appointed governor of the Roman province of Macedonia.
Marcus Junius Brutus and the other assassins, however, chose Macedonia as refuge from Octavian and - following opposition from Gaius - dispossessed him of his governorship.
