1031 – Macbeth succeeded his father, Findlaech (Sinel in Shakespeare), as mormaer, or chief, in the province of Moray, in northern Scotland.
1040 – Macbeth established himself on the throne after killing his cousin King Duncan I in battle near Elgin—not, as in Shakespeare, by murdering Duncan in bed on August 14th. Both Duncan and Macbeth derived their rights to the crown through their mothers.
1045 – Macbeth’s victory in 1045 over a rebel army, near Dunkeld (in the modern region of Perth and Kinross), may account for the later references (in Shakespeare and others) to Birnam Wood, for the village of Birnam is near Dunkeld.
1046 – Siward, earl of Northumbria, unsuccessfully attempted to dethrone Macbeth in favour of Malcolm (afterward King Malcolm III Canmore), eldest son of Duncan I.
1050 – Macbeth felt secure enough to leave Scotland for a pilgrimage to Rome.
1054 – He was apparently forced by Siward to yield part of southern Scotland to Malcolm.
1057 – Macbeth was killed in battle by Malcolm, with assistance from the English. He died on August 15th near Lumphanan, Aberdeen (now in Aberdeenshire), Scotland.
– Macbeth was buried on the island of Iona, regarded as the resting place of lawful kings but not of usurpers.
