In the Middle Ages, the Volga trade route connected Northern Europe and Northwestern Russia with the Caspian Sea and the Sasanian Empire, via the Volga River. The Rus used this route to trade with Muslim countries on the southern shores of the Caspian Sea, sometimes penetrating as far as Baghdad. The powerful Volga Bulgars formed a seminomadic confederation and traded through the Volga river with Viking people of Rus' and Scandinavia and with the southern Byzantine Empire Furthermore, Volga Bulgaria, with its two cities Bulgar and Suvar east of what is today Moscow, traded with Russians and the fur-selling Ugrians. Chess was introduced to Medieval Rus via the Caspian-Volga trade routes from Persia and Arabia.
