Changes Of The Roman Empire

The Roman empire had several significant challenges from the beginning of the millennium through the Byzantine empire. First, during the rule of Marcus Aurelius, German tribes invaded some of Rome and it began to ruin the whole empire. After Aurelius ruled his son Commodus took over, Rome's government was controlled by the military for a while. Rome's government changed for the worst during the rulership of Barracks Emperors. Diocletian, the last of the Barracks Emperors, was the first ruler, who attempted to restore the economy and make it more governable. But ruler Constantine continued Diocletian's policies and expanded to the east; the city of Byzantium.

Next, during the economic challenges Christianity become more popular as a religion.
