- This article is about the first Emperor of Rome. You may be looking for Octavian, Baron de Valois.
Augustus (Latin: Imperātor Caesar Dīvī Fīlius Augustus; 23 September 63 BCE – 19 August 14 CE) was the founder of the Roman Empire and its first Emperor, ruling from 27 BCE until his death. Born as Gaius Octavius, he was mainly known as Octavian before becoming Emperor.
After the assassination of Gaius Julius Caesar, Octavian formed an alliance with Marcus Antonius to eliminate the Assassins responsible for his death. The Roman army fought the rebels during the Battle of Philippi on 3 October 42 BCE, where Octavian was overrun by the army of Marcus Junius Brutus. Antonius was able to defeat Gaius Cassius Longinus, however, who then committed suicide. Twenty days later, Brutus himself suffered the same fate after the second Roman attack, and the battle ultimately ended in Roman victory.
