until the 15th century, a city and commercial center situated on the left bank of the Don River, near what is now the city of Azov. First mentioned at the end of the 12th century, Tana was the scene of competition between the Venetians and Genoese. It was governed by a council of the area’s wealthiest Italian merchants, with the local population (Alani, Russians, and Turks, among others) consigned to a state of dependency. The city had trade routes extending to the Volga, to Middle Asia and China, to the Northern Caucasus, to Transcaucasia, and to Iran and the Arab countries. The major products of the area were fish and caviar.
In the 13th and 14th centuries, Tana came under the control of the khans of the Golden Horde, with whom the Italian merchants concluded a series of treaties. In the late 14th century the city suffered from the effects of Tamerlane’s invasion. After 1475 it fell into the hands of the Turks and soon began its final decline.
