I am Marcus Aurelius the philosopher ruler and I brought the empire to the height of its economic prosperity.
The previous emperors were known as the good emperors. We were known for our skills as effective administrators and support of large building projects.
The empire enjoyed a period of peace during Pax Romana but after the reign of the good emperors a period of violence and corruption began in the empire.
Due to the many problems within the empire, the empire was broken into two halves. One emperor rules one half and a co-emperor ruled the other.
I am Constantine and I worked to stabilize the empire by reuniting the two halves of the empire. I moved the empire's capital to Constantinople (modern day Turkey) and I began to accept Christianity within the empire.
I am Theodosius and I willed that the empire should be separate empires. Eastern empire-Byzantine Empire Western Empire-Roman Empire
