 With a strong hold over the Uplands, Haakon was additionally given the earldom of Värmland by the Swedish king Stenkil.In early 1064, Haakon entered the Uplands and collected their taxes, the region thus effectively threatening to renounce their loyalty to Harald.The revolt of Haakon and the farmers in the Uplands may have been the main reason why Harald finally had been willing to enter a peace agreement with Sweyn Estridsson.
