 Malcolm III, King of Scots, held the Cumberland territory, (probably down to the River Derwent, River Eamont and Rere Cross on Stainmore line), until 1092, one year before his death in battle.The fact that he did this without challenge was partly the result, as far as the pre-Norman conquest era is concerned, of turmoil and alienation amongst the Northumbrian and Yorkshire nobles, (drawn from the ranks of the old Anglo-Saxon Bamburgh royal family and Danish/Norse nobles respectively), as well as the disaffection of the St. Cuthbert monks (in Durham), due to the rule of the West Saxon outsider Earl Tostig.Other factors include the absentee nature of Tostig's rule in the North, and his friendship with King Malcolm.
