How was Roman Empire split into western and eastern empire? What is the difference between the two empires?
The Roman Empire split into two parts when Emperor Diocletian decided to split it due to complications of administering such a huge empire. He kept the Eastern part while giving the rule of the Western Roman Empire to Maximian. The difference was, at the beginning, only in their geographical location (Eastern in the east with Constantinople as the capital, Western in the west with Rome as its capital). The differences in economic, political and religious character of the two empires grew in the centuries to come.
