n. native or inhabitant of Byzantium

The Byzantine Empire or Byzantium is the term conventionally used since the 19th century to describe the Greek-speaking Roman Empire of the Middle Ages, centered on its capital of Constantinople. The Empire is also known as the Eastern Roman Empire, although this name is more commonly used when referring to the time before the fall of the Western Roman Empire. During much of its history it was known to many of its Western contemporaries as the Empire of the Greeks because of the dominance of Greek language, culture and population. To its inhabitants, the Empire was simply the Roman Empire (Greek: ) and its emperors continued the unbroken succession of Roman emperors. In the Islamic world it was known primarily as (Rûm, land of the "Romans").
