Medieval Greek

Medieval Greek (Greek: Μεσαιωνική Ελληνική) is a linguistic term that describes the fourth period in the history of the Greek language. Its symbolic boundaries start with the transfer of the capital of the Roman Empire from Rome to Byzantium (Constantinople) in 330 AD, and end with the fall of Constantinople to the Ottoman Empire in 1453 AD, spanning therefore more than a millennium. As medieval Greek co-exists with the history of the Byzantine Empire, another term often used to describe the language of the period is Byzantine Greek.
