The Eyjarskeggjar (in modern Norwegian: Øyskjeggene) were a Norse rebel group during the Norwegian Civil War that supported the claim of Sigurd Magnusson to the throne.
The name eyjarskeggjar means "island beards," reflecting their origin in the Northern Isles.
[1][2] The Eyjarskeggjar confronted Sverre and his Birkebeiner supporters at the Battle of Florvåg in April 1194 and were decisively defeated.
Sigurd, Olav, and Hallkjell were all killed, effectively ending opposition to Sverre.
[3] Harald travelled to Bergen to disavow the Eyjarskeggjar, which allowed him to remain Jarl of Orkney and Caithness, although Sverre removed Shetland from his jarldom.
