The Hervarar saga tells that when Valdar died, his son Randver became the king of Sweden, while Harald Wartooth became the king of Denmark. Then Harald conquered all of his grandfather Ivar Vidfamne's territory. After Randver's death, his son Sigurd Hring became the king of Sweden, presumably as the subking of Harald. Sigurd Hring and Harald fought the Battle of the Brávellir (Bråvalla) on the plains of Östergötland where Harald and many of his men died. Sigurd ruled Sweden and Denmark until his death and was succeeded by his son Ragnar Lodbrok. Harald Wartooth's son Eysteinn Beli ruled Sweden as a jarl until he was killed by the sons of Ragnar Lodbrok.
