Byzantium

From Conservapedia

Byzantium, or Constantinople, was a city founded by the Roman Emperor Constantine the Great in 330 AD, and which shortly afterwards became the new capital of the Roman Emperor. It remained the capital of the eastern part of the empire when the empire was divided into two halves in 395 AD, and wheras the western half fell to Barbarian invasions in the space of less than a century, the eastern half survived through the entire Medieval period, gradually growing weaker and smaller, until Constantinople finally fell to the Turks in 1453 AD. It is today the Turkish city of Istanbul.
