|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; 63 BCE – 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 known mainly as Octavian before becoming Emperor.
Following the the assassination of Julius Caesar, Octavian's maternal great-uncle and adoptive father, Octavian formed an alliance with Marcus Antonius in order to eliminate the Senators responsible for Caesar's death, many of whom were members of the Hidden Ones. Octavian's army fought the rebel forces led by Marcus Junius Brutus during the Battle of Philippi on 3 October 42 BCE, but was defeated. Antonius, however, was able to defeat Brutus' ally and fellow Hidden One, Gaius Cassius Longinus, who subsequently committed suicide. Twenty days later, Brutus himself suffered the same fate after a second battle with Octavian, one which ended in victory for the future emperor.
Octavian soon took power in Rome and began waging a series of civil wars to consolidate his strength. In the late 30s BCE, he waged war against the allied armies of Antonius and Cleopatra. Antonius committed suicide, leading Cleopatra to withdraw to the city of Alexandria in 30 BCE. Octavian's army besieged the city and expected to capture the Pharaoh. However, she instead committed suicide with a vial of poison given to her by Amunet.
