What did the roman emperor Augustus do that was so good to rome?
You already have some good answers here, so I’ll just add a little bit. Prior to Augustus, Rome was in chaos from civil war and a republican government that was so prone to infighting, greed and class warfare that it simply could no longer deal with the problems of the day. Augustus ended the Republic and replaced it with the Empire, concentrating supreme power in the emperor, thereby ending all sources of infighting. He then when on to institute a series of reforms to deal with the other problems. His rule was long and successful, and it started the Pax Romana which, which brought almost two centuries of peace and prosperity to Rome.
