Kenneth MacAlpin

Kenneth I, called Kenneth MacAlpin (c. 810–858), was king of the Picts. Tradition holds that he succeeded his father Alpín as king of Dál Riada around 841 and conquered the Picts between 843 and 850, after which he was hailed as founder of Scotland, or Alba, and surnamed the Conqueror.

He warred against the Britons of Strathclyde and Viking raiders, and moved the Stone of Scone and other relics from Iona into his kingdom. He died on 13 February 858 and was succeeded by his brother Donald.
