Durham's location in the north left it insecure, as Malcolm Canmore, King of Scots, raided and invaded the north of England on a number of occasions. Malcolm claimed Northumbria, in which Durham was located, as part of his kingdom. St-Calais managed to befriend Malcolm, and secured his support for the patron saint of Durham, Saint Cuthbert. Malcolm and his wife helped lay the foundation stone of the new cathedral dedicated to Cuthbert. Respect for the saint did not mean that Malcolm refrained entirely from raiding the north; he was killed in 1093 while once more raiding Northumbria. Both the English king and St-Calais did all in their power to support Malcolm's sons, who had been educated in England, in their attempts to secure the Scottish throne.
