The Bagler party dissolved, and the under-age Haakon IV became king of Norway, with jarl Skule Bårdsson as de facto ruler.
As Skule's honored prisoner, Sigurd was present at a gathering of all the most powerful men of Norway, which was convened in Bergen in 1223 to finally settle who would be king.
After Sigurd's death, the Ribbunger sought out another of the candidates for the throne, Knut Håkonsson, and declared him to be their new king.
However, the rising was now a spent force, and Knut surrendered to King Haakon in 1227, ending the Ribbung rebellion.
The background for these conflicts were the unclear Norwegian succession laws, social conditions and the struggle between Church and King.
The main source to Sigurd Ribbung's life and rebellion is Sturla Þórðarson's Saga of Håkon Håkonsson, which was written in the 1260s.
