Byzantium (Βασιλεια Ρωμαιων ,Ρωμανια , Romania or Eastern Roman Empire )

The Byzantine Empire or Eastern Roman Empire was the Roman Empire during the Middle Ages, centered on the capital of Constantinople, and ruled by emperors in direct succession to the ancient Roman emperors. It was called the Roman Empire, and also Romania, by its inhabitants and its neighbours. As the distinction between "Roman Empire" and "Byzantine Empire" is purely a modern convention, it is not possible to assign a date of separation, but an important point is the Emperor Constantine I's transfer in 324 of the capital from Nicomedia (in Anatolia) to Byzantium on the Bosphorus, which became Constantinople (alternatively "New Rome").
