Augustus

Augustus Caesar, born Gaius Octavius Thurinus, or simply Octavian, was the first Imperator of Rome and principal founder of the First Roman Empire.

Early Life
Octavian was born in 63 BCE to Atia, Caesar's niece, and a governor of Macedonia who shared the same name. A precocious boi, he entered the Collage of Pontiffs at the age of sixteen, and impressed his uncle Caesar with his eagerness to prove his military capacity and fortitude. They became very close, perhaps lovers, but that's not really our business.

Less Early Life
After Caesar died in 44 BCE, he named Octavian his heir, which was really a curveball for Marc Antony, who had thought he was the favorite. Even so, Octavian and Antony joined forces to deal with the traitors, along with their flip-flopping pal Lepidus. After killing Brutus and Cassius, they could now focus on undermining each other. Octavian, Marc Antony, and Lepidus formed the Second Triumvirate, and divided the Empire amongst themselves.
