In this way the earl came into possession of all the udal lands in the Orkneys; and it was not till the time of Earl Sigurd the Stout, a century later, that the udal rights were restored to the Orkneymen. Earl Einar spent the rest of his days in peace. The earldom was well ruled. Vikings were afraid to plunder the dominions of so powerful a chief; and after a long and honourable reign the good earl died on a sickbed—what the Vikings called a “straw death”—about the year 933. [Illustration: _Remains of a Viking Ship found in Sweden._] THE DARK CENTURY. The tenth century may fittingly be called the dark century of Orcadian history. We know very little of it except occasional glimpses afforded by obscure references in the Sagas; and the little that we do know tells of treachery and bloodshed and murder to an extent unusual even in the troubled annals of Orkney. After the death of Torf-Einar the earldom came into the hands of his three sons, Thorfinn—usually called Thorfinn Skull-splitter—Arnkell, and Erlend. The disturbed state of Norway, consequent on the death of Harald Fairhair about the year 945, caused turmoil and confusion throughout all those lands which had been conquered and settled by the Norsemen. Harald left behind him a brood of wild, reckless sons, each of whom thought he had a right to a share of his father’s dominions. They filled the whole land with turbulence and bloodshed. Eric Bloody-axe had been Harald’s favourite son, and he at first took over the chief rule in Norway. He was a brave and skilful warrior, but passionate, avaricious, and treacherous in his disposition. The same qualities were possessed in an even greater degree by his queen, Gunnhilda. Their deeds of violence soon estranged the hearts of their subjects. Hakon, Harald’s youngest son, who had been brought up in England under the care of King Athelstan, came to Norway to claim his share of his father’s dominions. Hakon was at this time only in his fifteenth year, but he was daring and ambitious, and was the darling of the Norsemen both at home and abroad. Eric Bloody-axe and Gunnhilda were, on the other hand, regarded everywhere with hatred and detestation. When, therefore, Hakon invaded Norway and attempted to wrest the sovereignty from the hands of his elder brother, the latter was deserted by his people and was forced to flee from the country. Eric crossed first to Orkney, where he gathered a band of followers as reckless as himself, and then held on to England and began to ravage the land in the usual Viking fashion. Close friendship had long existed between Athelstan and Harald Fairhair. Athelstan professed similar friendship for Harald’s sons, and now offered Eric the lordship of Northumbria. Eric was not so foolish as to reject this offer. Gunnhilda and he with their family abode in peace in Northumbria for about a year.
