'Alexander I succeeded as next brother of Edgar. His reign is chiefly remarkable for the determined struggle which he made in defence of the independence of the Church of Scotland. This was maintained against the archbishops of Canterbury and York, each of whom claimed a spiritual superiority over Scotland, and a right to consecrate the archbishop of St. Andrew's, the primate of that kingdom. Notwithstanding the hostile interference of the pope, Alexander, with considerable address, contrived to play off the contradictory pretensions of the two English archbishops against each other, and thus to evade complying with either. Of Alexander's personal character we can only judge from the epithet of the fierce, which referred probably to his own temper and manners, since assuredly his reign was peaceful. He died 1124.'
