Origins. Trebizond already had a long history of autonomous rule before it became the center of a small empire in the Late Middle Ages.Due to its natural harbours, defensible topography and access to silver and copper mines, Trebizond became the pre-eminent Greek colony on the eastern Black Sea shore soon after its founding.
