In the following video we will analyze the legacy of Björn Ironside, who according to the 12th- and 13th-century Scandinavian histories, was the son of notorious Viking king Ragnar Lodbrok and lived in the 9th century, between 855 and 858. Björn Ironside is said to have been the first ruler of the Swedish Munsö dynasty.
