The Roman Empire Constantine I determined to move his capital from Rome to Byzantium (Greek colony) in 330 A.D. Constantine I renamed the city as Constantinople. Constantine resolved to change his capital to the ancient Greek colony to check the enemy approaches from Danube and Persia. Its geographic position helped him to establish an empire because of its trading network and coastal city. The region was also picked because of the barbarian and Persian Empire continually attacking the empire in Rome.
