Rome: From the Late Republic to the Fall of the Roman Empire: 121 BC to 476 AD
From 121 BC onwards, the political fortunes of Rome were dominated by powerful leaders. Marius - the military reformer, Sulla - the dictator, Cicero - the lawyer, orator and consul, and Julius Caesar who appointed himself dictator in 45BC. When the Roman fleet destroyed the Egyptians at the Battle of Actium, Augustus became the first Roman Emperor. The rule of the Julio-Claudian emperors, notably Caligula and Nero, were a disgrace. During the period of the Five Good Emperors - Nerva, Trajan, Hadrian, Antoninus Pius and Marcus Aurelius—the Roman Empire was at its greatest. Eventually, Vandals, Goths, Burgundians, and Alani invaded, and the Empire finally fell in 476 AD.
