Björn Ironside

Björn Ironside is said to have been the first ruler of the Swedish Munsö dynasty. According to the 12th- and 13th-century Scandinavian histories, he was the son of the notorious and historically dubious Viking king Ragnar Lodbrok. His descendants in the male line supposedly ruled over the Swedes until c. 1060. He is first mentioned in the summer of 855.
