The fur trade, which runs from the Scandinavia to the Caspian Sea,began to focus from the 6th century. The historical process that causes this situation, began with encounters of some of the Slavic tribes , spreading from the field of Middle Ozi(Dnieper) northerly to the surroundings of Lake Ladoga and İlmen with Fin societies in the 6-8th century. In the 8th century Normans which penetrated to the Ladoga and İlmen Lake surroundings, spread in the direction of upper Idil (Volga) and Ozi River. So Normans arrived the Khazar country through the Idil River and also came down to the Black Sea through the Ozi and contacted the Slavs there. In the following process, Normans and later Russian merchants, sold valuable furs they receive from Fin and Slavic people, especially to Islamic countries under the patronage of Idil Bulgarian states.
