The Rus' undertook several Caspian expeditions in the course of the 10th century. The "Yngvars saga víðförla" describes the last Viking campaign in the Caspian in 1041, embellishing the historical facts with a great deal of legend. The expedition probably aimed to reopen old trade-routes after the Volga Bulgars and the Khazars no longer proved obstacles. Ingvar the Far-Travelled launched this expedition from Sweden, travelling down the Volga River into the land of the Saracens (Serkland). While there, the Vikings apparently took part in the 1042 Battle of Sasireti between the Georgians and Byzantines in Georgia.
