Notes for King of Scotland Malcolm III Canmore:
Source: WFT CD 0514 -
Malcolm III founded the house of Canmore, which ruled Scotland for more than 200 years and consolidated the power of the Scottish monarchy. He was the son of Duncan I, who was killed by MacBeth in 1040. Malcolm lived in exile until 1057, when he defeated and killed MacBeth near Lumphanan in Aberdeenshire. He succeeded to the throne in 1058 after the death of Lulach, MacBeth's stepson.

Malcolm's second wife was Margaret (later canonized as Margaret of Scotland) of the English royal house of Wessex, who fled to Scotland after the Norman conquest of England in 1066. She introduced a powerful English influence in Scotland.

Malcolm invaded England many times, after 1068 supporting the claim of his brother-in-law Edgar Atheling to the English throne. In 1072, however, he was forced to pay homage to William I, and in 1091, to William II. He was finally defeated and killed by Norman forces at Alnwick. He was succeeded briefly by his brother Donald Bane and them by his son Duncan II. Three other sons also succeeded to the throne--Edgar(1097-1107), Alexander I(1107-24) and David(1124-53).
