The Volga River, at 3690 km, is the longest river in Europe and 16th in the world. The geographical situation of the Volga promoted human colonization by various nations and played an important role in the movement of people between east and west (from Asia to Europe) as well as south and north. The present ethnographic composition of the Volga reg...
