In the 9th century viking settlers established the Kingdom of the Isles throughout the Hebrides. Nevertheless, although evidence of viking settlement has been found in both North and South Uist, there has not yet been found any sign of viking settlement on Benbecula itself. Following Norwegian unification, the Kingdom of the Isles became a crown dependency of the Norwegian king; to the Norwegians the Kingdom was "Suðreyjar" (meaning "southern isles"). Malcolm III of Scotland acknowledged in writing that Suðreyjar was not Scottish, and king Edgar quitclaimed any residual doubts.
