Augustus established the form of
government under which Rome ruled the empire for 300 years.
He was the first of the Roman emperors and restored peace after 100 years of civil war and Rome reached its greatest glory under his reign which was also the golden age of Roman literature and architecture.
Augustus introduced a system of succession whereby the emperor designated a member of his family as successor. As a result, for more than two hundred years, the Roman world remained internally at peace.
