The Pax Romana (Latin for "Roman Peace") is a roughly 200-year-long timespan of Roman ancient history which is identified as a period and golden age of increased as well as sustained Roman imperialism, order, prosperous stability, hegemonial power and expansion, despite a number of revolts, wars and continuing competition with Parthia. It is traditionally dated as commencing from the accession of Caesar Augustus, founder of the Roman principate, in 27 BC and concluding in 180 AD with the death of Marcus Aurelius, the last of the "Five Good Emperors". Since it was inaugurated by Augustus with the end of the Final War of the Roman Republic, it is sometimes called the Pax Augusta. During this period of approximately two centuries, the Roman Empire achieved its greatest territorial extent and its population reached a maximum of up to 70 million people.
