Erik Björnsson

Erik Björnsson was supposedly one of the sons of Björn Ironside and a legendary king of Sweden of the House of Munsö, who would have lived in the late 9th century. One of the few surviving Scandinavian sources that deal with Swedish kings from this time is Hervarar saga. The saga is from the 12th or 13th century and is thus not considered a reliable historical source for the 9th century. It says:

The sons of Björn Ironside were Eric and Refil. The latter was a warrior-prince and sea-king. King Eric ruled the Swedish Realm after his father, and lived but a short time. Then Eric the son of Refil succeeded to the Kingdom.
