[All]: There were political reasons for the marriage of Ríkiza and Hákon ungi. In 1225 King Hákon invaded Värmland, as Sturla mentions in Hákkv 7-8, and Jarl Birgir was anxious to avoid further conflict with the Norw. king. At a meeting in 1249, they promised not to support each other’s enemies. In addition, Hákon gained the support of the jarl in his aggressive policy towards the Danes and could focus on expanding his state to the south (Helle 1974, 128-9).
