 Einar Thambarskelfir and Kalf Arnesson, who had both sought to be appointed regents under Cnut after Olaf's death in 1030 (Cnut instead appointed Svein and Ælfgifu), went together to Kievan Rus' to bring the boy back to rule as the King of Norway.After receiving the approval of Ingegerd, they returned with Magnus to Sigtuna in early 1035, and received backing from the Swedish king, brother of Magnus's stepmother Astrid.Astrid immediately became an important supporter of Magnus, and an army was gathered in Sweden, headed by Einar and Kalf, to place Magnus on the Norwegian throne.
