Byzantium
ancient Greek city, precursor of Constantinople / From Wikipedia, the free encyclopedia
Not to be confused with Byzantine Empire.
Byzantium (Greek: Βυζάντιον) was an ancient Greek city. The name "Byzantium" is a Latinization of the original name Byzantion.
The city became the center of the Byzantine Empire, (the Greek-speaking Roman Empire of late Antiquity and the Middle Ages), but at that time it was already called Constantinople.[1]
