king of ‘Scotland’ (900–940/5). His father was *Æd (d. 878). Constantine II laid the foundations of the kingdom of Scotland. His victory over the Danes at Strathearn in 904 represented a turning‐point in its struggle against Scandinavian aggression, and after another victory at (probably) Corbridge (west of Newcastle) in 918 he initiated a policy of rapprochement with the Danes cemented by the marriage of his daughter to the Danish king Guthfrith. This was designed to support Danish York in its struggle for survival against kings of Wessex. The kings of Wessex began to threaten Scotland itself when Athelstan invaded as far as Dunnottar in 934, and in 937 an invasion of England mounted by Constantine and the Danes from Dublin led by Guthfrith's son Olaf ended in disaster at the battle of Brunanburh.
