Constantine (Constantín mac Cináeda) son of Kenneth MacAlpin and brother of Aedh, he became king on the death of his uncle Donald. For much of his reign he was faced with repeated attacks from Vikings including the forces of Olaf the White based in Dublin who reportedly took many Albans and Britons as slaves. Olaf besieged and sacked Dumbarton. The Strathclyde king Artgal survived, but was assassinated the following year with the connivance of Constantine.

In 875 Constantine was killed fighting the Vikings at Inverdovat, near Newport-on-Tay, Angus. He was buried on Iona and succeeded by his brother Aedh.
