The first season depicts Julius Caesar's civil war of 49 BC against the traditionalist conservative faction in the Roman Senate (the Optimates), his rise to dictatorship over Rome, and his fall, spanning the time from the end of his Gallic Wars (52 BC or 701 "ab urbe condita") until his assassination on 15 March 44 BC (the infamous Ides of March). Against the backdrop of these cataclysmic events, we also see the early years of the young Octavian, who is destined to become Augustus, the first Emperor of Rome. The second season chronicles the power struggle between Octavian and Mark Antony following Caesar's assassination, spanning the period from Caesar's death in 44 BC to the suicide of Antony and Cleopatra in 30 B.C. after their defeat at the Battle of Actium.
