Reign 25 Mar 1005-25 Nov 1034. Malcolm became king of Scots in 1005, after killing his cousin and predecessor Kenneth son of Dub in a battle. He led an attack on Durham, England in 1006, but was decisively defeated after the siege was broken. The most important event of his reign was probably the battle of Carham, which occurred in either 1016 or 1018. Malcolm led an invasion of Northumbria, and his victory pushed the Scottish realm well into traditional English territories. An important consequence of the battle was the death of Owen, the last native king of Strathclyde, which, from this point on, was part of the kingdom of the Scots.
A notable external event was Malcolm's meeting with King Canute of England in 1031.
Malcolm had no sons, but he apparently wanted his descendants to rule the Scots, so he tried to revolutionize succession practices by arranging to have one of his grandsons succeed him. To this end, he had competing claimants of the house of Alpin murdered in the early 1030's. Upon his death he was succeeded by his grandson Duncan.
