Byzantine Empire is a term which has been coined by historians to indicate the eastern part of the Roman Empire after the fall of the western part of this empire. The eastern part continued to exist for nearly 1,000 years after the fall of the western part.

Constantine modeled his new city after Rome. He even called Constantinople the "new Rome." Another name for the eastern empire is Byzantine. The Byzantine empire was the eastern part of the roman empire that did not fall with the rest of the western part of the empire.
