After the Roman Empire fell, the remnant, the Eastern Empire came to be known as the Byzantine Empire. The Byzantine emperors called themselves Emperors of the Romans.   **Actually the answer above is a bit off the mark. Constantine was the Emperor who reunited the Empire.
The Byzantine Empire originated with the founding of Constantinople in the fourth century AD on the site of the much older Greek colony of Byzantium. The Roman Emperor Constantine I [died 337] called the site New Rome or Constantinople. Constantine situated his capital in the new city named after himself. The successors of Constantine I lived in Constantinople without interruption until 1204. In 1204, Crusaders from Western Europe, diverted from the path to Jerusalem, captured and looted Constantinople. They held the city until 1261.
