A major trade centre since times immemorial, and visited by Marco Polo among many others, Trabzon is today one of the major cities of Turkey’s northeastern coast.
In medieval times, city served as the capital of Empire of Trebizond, which was ruled by Komnenos family —which also provided several emperors to the Byzantine throne in Constantinople. The longest surviving rump Byzantine state, Trabzon was captured by Ottoman Turks in 1461, almost a decade after the fall of Constantinople.
