Notes about SIGURDA MacCausantin Queen of Scots (Alba) 30th GGM

The Jarldom of Orkney (Old Norse: Orkneyjar) was a Norse state in northern Scotland founded during the Viking period, which at different periods controlled Orkney, Shetland, and parts of Caithness and Sutherland. Norwegian settlement in Orkney began in the eighth century, with a jarldom under Norwegian rule being officially established around the year 875. The islands would be granted to the Jarl of Møre, Rognvald Eysteinsson, son of Eystein Glumra, Jarl of Oppland and Hedmark, by Norwegian king Harald Fairhair, in compensation for the death of the Jarl's son while campaigning under Harald to conquer the islands. Rognvald's descendants, through his youngest son Turf-Einar, the son of a concubine on his mother's side, would rule the Jarldom of Orkney for years to come, establishing a stable dynasty in the North Sea.

During the Strathclyde War the Jarl of Orkney, Thorfinn Torf-Einarsson, allied with Eirik Bloodaxe, the former King of Norway, who created the Jarldom of Suðrland in northern Scotland. The defeat of Scottish forces in the north would lead to further territorial gains for Orkney in the coming years, who profited from an ally on the Scottish mainland.

Before Norse rule Orkney had been settled by Pics during the Bronze Age. Settlement by the Norse was largely carried out by Vikings seeking conquest, as well as farmers in search of land. It is unclear what became of the native Pict population, although they were likely massacred, assimilated, or forced to flee back to Scotland.
