(d. 877),

‘king of the Picts’ (862–76), anachronistically regarded as third king of Scotland. Son of Kenneth I, he succeeded his uncle Donald I. His career was chiefly consumed in a desperate struggle for survival against Scandinavian incursions. In 866 the Norwegian king of Dublin devastated Pictland and in 875 Halfdan the Danish king of York inflicted a crushing defeat on Constantine at Dollar. Constantine was killed in 877 by the Danes at ‘Inverdufata’ (unidentified).
