Trabzon, historically known as Trebizond is a city on the Black Sea coast of northeastern Turkey and the capital of Trabzon Province. Trabzon, located on the historical Silk Road, became a melting pot of religions, languages and culture for centuries and a trade gateway to Persia in the southeast and the Caucasus to the northeast. The Venetian and Genoese merchants paid visits to Trebizond during the medieval period and sold silk, linen and woolen fabric; the Republic of Genoa had an important merchant colony within the city called Leonkastron that played a role to Trebizond similar to the one Galata played to Constantinople (modern Istanbul). Trabzon formed the basis of several states in its long history and was the capital city of the Empire of Trebizond between 1204 and 1461. During the early modern period, Trabzon, because of the importance of its port, became a focal point of trade to Persia and the Caucasus.
