Боспорское царство
The Bosporan Kingdom covered the eastern half of Crimea and the Taman peninsula, and extended along the east coast of the Maeotian marshes to Tanais at the mouth of the Don in the north-east, a great market for trade with the interior. Throughout the period there was perpetual war with the native tribes of Scythians and Sarmatians, and in this the Bosporan Kingdom was supported by its Roman suzerains, who lent the assistance of garrisons and fleets.
