Fact · North Uist
Uist was Norwegian until it was sold for 4,000 marks
Uist was part of Norway for about two centuries. The Treaty of Perth in 1266 handed the Hebrides and the Isle of Man to Scotland in exchange for 4,000 marks, three years after the Battle of Largs.
Viking settlers established the Kingdom of the Isles across the Hebrides in the ninth century, and Norwegian control was formalised in 1098 when Edgar of Scotland signed the islands over to Magnus III of Norway. They were the Suðreyjar, the Southern Isles. On 2 July 1266 Magnus the Lawmender and Alexander III signed the Treaty of Perth, transferring the Hebrides and Man to Scotland for 4,000 marks. Norse survives in almost every place name on Uist, from Lochmaddy's Maddies to Eriskay itself, Eric's isle.
