The Second Triumvirate is the historical name given to the ancient Roman alliance of Octavian, Marc Antony, and Marcus Aemilius Lepidus, established in 43 BCE. Unlike the First Triumvirate, it was an official, if extraconstitutional, organization that was legally established and given enormous power by the senate. After Lepidus was deposed and Antony defeated, Octavian became the first emperor of Rome in 27 BCE. Octavian is better known by what name? Discuss
