Father: Possibly Emund Eriksson.
Erik is the first King that we can say was king over all of Sweden. He succeded Emund Eriksson. (See The Earliest Kings)
He was married, but we do not know for sure to whom. It was either Sigrid Storråda, daughter of Skoglar Toste, or Princess Gunhild of Poland, daughter of Prince Mieszko and sister till Boleslav I, Poland's first king. Other sources talk about a Slavic princess. His widow is anyhow said to have married King Sven of Denmark and England. Son: Olof.
Erik Victorious is famous for his victory over Vikings at Fyrisvallarna
near Uppsala abt 985.
