The nephew and chosen heir of Gaius Julius, Caesar before him, Augustus was the first Emperor of Rome and the architect of the Empire. His accession was not a simple one, though – it’s worth noting that it took 17 years from the death of the divine Julius for him to ascend to the throne in his own right.
He first formed a triumvirate with Mark Antony and Marcus Lepidus, but it was never a smoothly running system. Before long, war broke out between the three, with Lupidus and Antony battling Octavian (as Augustus was then known). Unfortunately for them, Octavian was better general than either of them, which is why he wound up being Emperor Augustus and they wound up being dead.
