Ragnar Lodbrok or Lothbrok (Old Norse: Ragnarr Loðbrók, "Ragnar Hairy Breeches") was a legendary Norse ruler and hero from the Viking Age described in Old Norse poetry and several sagas. In this tradition, Ragnar was the scourge of France and England and the father of many renowned sons, including Ivar the Boneless, Björn Ironside, Halfdan Ragnarsson, Sigurd Snake-in-the-Eye, and Ubbe Ragnarsson.
Björn Ironside was the son of the Danish/Scandinavian king Ragnar Lodbrok and he had the brothers Hvitserk, Ivar the Boneless and Sigurd Snake-in-the-Eye, and the half-brothers Eric and Agnar. Björn and his brothers conquered all of Sweden. When Ragnar died Björn Ironside inherited Sweden. He had two sons, Refil and Erik Björnsson, who became the next king of Sweden.
