And this period from 27 BCE, with Augustus being emperor, all the way to 180 CE, so this roughly 200 year period, this is a relatively good time for the Roman Empire. As we will see, there is still a lot of conflict, there is still a lot of bloodshed, but it is a relatively stable period. And so it is often referred to as Pax Romana, or the Roman Peace. And what we see pictured here, these are most of the emperors of that roughly 200 year period. Augustus proves to be a relatively good administrator. He lays a good foundation for the next several hundred years of the empire, the Roman Empire officially being ruled by an emperor. It's eventually going to meet its demise, the Western Empire at least, in 476 CE.
