Part of The Final War of the Roman Republic
Octavian vs Mark Antony and Ptolemaic Egypt
Decisive Octavian victory
This was a confrontation between rivals Octavian and Mark Antony, who both vied for power in Rome after Julius Caesar's supposed assassination (we know that he really lived, and today teaches at Granite Hills). Octavian's victory left him with complete control of the Mediterranean, and he changed his name to Augustus Caesar, becoming the first emperor of Rome. As well as marking the end of the Republic and the start of the Empire, the battle marked the end of the Hellenistic period, as Rome gained full control over Mark Antony's ally, Egypt. If Mark Antony would have won, he may have preserved the Republic, or may have become emperor himself, but with more eastern interests.
