In the aftermath, groups made up principally of the Norwegian aristocracy, clergy and merchants were formed to depose King Sverre.
As the son of Magnus Erlingsson, Sigurd was the nominal king supported by the so-called Isle Beards (Eyjarskeggjar) from Shetland and Orkney.
The real leader was Hallkjell Jonsson, who had been a son-in-law of Erling Skakke as well as the brother-in-law of King Magnus.
[7] [8] Sigurd Magnusson's corpse was shown in Bergen, in order to demonstrate King Sverre's power and also to prevent any impostors claiming to be the young prince.
The background for these conflicts was the unclear Norwegian succession laws, social conditions and the struggle between Church and king.
This saga is likely biased, since the foreword states that part was written under King Sverre's direct sponsorship.
