The consequence of King Hakon's failure was the immediate conquest of the Isle of Man and of the Hebrides by Alexander III.
Sutherland and Caithness were saved for Scotland, it would seem, only by the vote of King Hakon's freemen before sailing for Largs, while the defeat of his fleet there led directly to the cession by King Magnus, his successor, under the treaty of Perth in 1266, of all the Western Highlands and Islands, for a payment of 4000 marks down and of 100 marks a year, and the treaty also secured their permanent political union with Scotland.
Orkney and Shetland, however, remained part of Norway for two hundred years more, and have since 1468 been held by Scotland and afterwards by the United Kingdom only under a wadset or mortgage securing 58,000 crowns, the unpaid balance of the dower of Margaret, wife of James III of Scotland and daughter of King Christian of Norway. The right to redeem them was frequently though fruitlessly claimed by Norway and Denmark in succession until the reign of Charles II and even later; and possibly this right remains, to the legal mind, open until the present day.
On the 20th February 1471 the Earldom of Orkney and Lordship of Shetland were, by an Act of the Scottish Parliament, finally annexed to the Scottish Crown. But Norse law and usages and the Norse language long lived on in Orkney and longer still in Shetland.
CHAPTER XI.
Results and Conclusion.
Restless energy, and a religion that taught its followers that death in combat alone conferred on the happy warrior a title to immortal glory and a perpetual right to the unbroken joy of battle daily renewed in Valhalla drove the Viking to war.
Headed off on the south by the vast army and feudal system of Charlemagne, this energy in war could be exercised, and its religious aims achieved, solely on the sea, which skill in shipbuilding and in navigation as well had converted from a barrier into a highway to the west.
