Following the end of the war, Octavian brought peace to the Roman state that had been plagued by a century of civil wars. Octavian became the most powerful man in the Roman world and the Senate bestowed upon him the name of Augustus in 27 BC. Octavian, now Augustus, would be the first Roman Emperor and would transform the oligarchic/democratic Republic into the Roman Empire. The last Republican Civil War would mark the beginning of the Pax Romana, which remains the longest period of peace and stability that Europe has seen in recorded history.
