One major accomplishment of Augustus Caesar was that he restored and maintained peace in the city of Rome, also known as the Pax Romana. Prior to Augustus, Rome was a city plagued with civil disobedience, class wars and greed.
Rome was initially ruled by a Republican government. Augustus ended the Republic rule and gave supreme power to the Emperor. Augustus also made peace with the Parthian Empire, reformed taxation, developed roads and established a courier system. He established the Praetorian Guard and overall rebuilt the city into one that was secure and fruitful. The rule of Augustus was long and successful, keeping Rome free from any major form of conflict for more than two centuries.
