The Pax Romana, more than 180 years of Peace in the Roman World, was the hallmark of the early Imperium. This great era of peace (no major wars with in the confines of the Empire) in Western Europe, North Africa and the Mediterranean coast of the Middle East began under the reign of the Emperor Augustus. Peace reigned within the Empire from this time period up to the end of the rule of Emperor Marcus Aurelius (last of the "Five Good Emperors"). In some areas of the Empire such as Britinnia the Pax Romana lasted for over four centuries. The Pax Romana is an accomplishment yet to be duplicated in human history.
