The Last Emperor

S1, E13: In the middle of the 5th century, as the Empire fights a losing battle against its formidable barbarian opponents, one Roman named Orestes finds service in the court of Attila the Hun. Schooled in the strategy of his enemy, Orestes eventually makes his way back to Italy, determined to resurrect Rome. But first, he must face down barbarians in the royal court, and pretenders sent from the East. Naming his young son, emperor, Orestes attempts to purify Rome of her barbarian influences. However, he learns the sad truth that without barbarians, there is no Rome. After hundreds of years of using the foreign invaders as mercenary soldiers, they outnumber the Romans, and the Empire can't afford to dismiss them. Though Orestes fights valiantly, he meets his end at the hands of the leader of the barbarian mercenaries, Odacer--an event that spells the end of Rome in 476 AD. The last emperor, just a boy, is sent into exile, and the Roman Empire is no more.
