Igigerda and Olaf II were in a loving correspondence, in addition, it is known that the Norwegian king sent his bride a golden ring and other valuable gifts. There is reason to believe that Ingigerda sought this marriage, but her father Olaf Shötkonung preferred another candidate - the Novgorod prince Yaroslav Vladimirovich. In 1016 Yaroslav took Kiev, and the Swedish king bet on the main pretender to the throne of Kiev. It is necessary to note, that the groom was about 20 years older than the bride. The wedding took place in 1019. As dowry Ingigerda received Aldeigaborg town (today it is Old Ladoga village) with lands nearby. Subsequently the area received the name Ingermanlandia. The Swedish princess took the orthodox name of Irina.
