Regency
Her son Magnus VII of Norway, at the age of 3, was proclaimed king of Norway upon her father's death, in rights devolved from her. Ingeborg was recognized as formal regent of her son in Norway. Soon, the Swedish nobility elected young Magnus king of Sweden after deposing Birger, and Ingeborg was made nominal regent of Sweden and given a seat and vote in the Swedish government and the title: Ingeborg, by the Grace of God, daughter of Haakon, Duchess in the Kingdom of Sweden. Duchess Ingeborg held her own court at her residence in Varberg.
The exact position of Ingeborg in the regency council is hard to define properly due to the documentation. Mats Kettilumndsson, her ally, presided over the Swedish regency council "alongside" the two "Duchesses Ingeborg"; Ingeborg Håkansdotter and her cousin and sister-in-law Ingeborg Eriksdottir. Magnus, already King of Norway, was elected King of Sweden with the approval of the Norwegian council in her presence. Ingeborg was the only one with a seat in both the Swedish and the Norwegian minor regency and council of state. She was the independent reigning duchess of her own fiefs, which were autonomous under her rule, and a large number of castles which controlled big areas thanks to their strategic positions.
