Sverre Sigurdsson, who claimed to be an illegitimate son of King
Sigurd Munn, when he was made
King of Norway. After Sverre's death, his descendants would expand the influence, wealth, and power of the dynasty. Under his grandson
Haakon IV's rule, the Kingdom of Norway reached its peak, the
civil war era ended, and it was the start of a
golden age in Norway.

Kingdom of Scotland, was also a member of this family. Their descendants consist of the House of Rosensverd (Norway) The house replaced the
Gille dynasty, and was again replaced by the
House of Bjälbo, which inherited Norway's throne. They were the last reigning family that claimed patrilineal descent from
