As one of the heirs of his maternal grandfather King Inge I, Magnus claimed Sweden. He was recognized King of Götaland or parts thereof by the Geats ("Götar") in c. 1129 after the death of his mother's cousin King Inge II. Then Richeza became Queen consort of Sweden. However, Magnus' rule was not accepted by the Svear, another tribe to the north of the Geats, who vetoed him and elected Ragnvald Knaphövde as the new King. According to the chronicler Saxo Grammaticus, Ragnvald was murdered by supporters of Magnus, who then won the realm ("imperium") as King of Sweden. However, there soon appeared another contender for the throne, Sverker I, who had his power base in Östergötland.
