Answer:
The Pax Romana was established under Augustus, and for that reason it is sometimes referred to as the Pax Augusta. Augustus closed the Gates of Janus three times to signify the onset of peace: in 29 BCE, 25 BCE, and 13 BCE, likely in conjunction with the Ara Pacis ceremony. The Romans regarded peace not as an absence of war, but as the rare situation that existed when all opponents had been beaten down and lost the ability to resist. Thus, Augustus had to persuade Romans that the prosperity they could achieve in the absence of warfare was better for the Empire than the potential wealth and honor acquired when fighting a risky war. The Ara Pacis is a prime example of the propaganda Augustus employed to promote the Pax Romana, and depicts images of Roman gods and the city of Rome personified amidst wealth and prosperity.
