Haakon Sigurdsson, jarl of Hlaðir, arranged the death of Harald Greyhide around 971 with the connivance of Harald Bluetooth, who had invited his foster-son to Denmark to be invested with new Danish fiefs. Civil war broke out between Jarl Haakon and the surviving sons of Erik and Gunnhild, but Haakon proved victorious and Gunnhild had to flee Norway once again, with her remaining sons Gudrod and Ragnfred. They went to Orkney, again imposing themselves as overlords over Jarl Thorfinn. However, it appears that Gunnhild was less interested in ruling the country than in having a place to live quietly, and her sons used the islands as a base for abortive raids on Haakon's interests; the government of Orkney was therefore firmly in the hands of Thorfinn.
