was killed on this date in 1057. But not as Shakespeare portrayed it. Here’s the story from the BBC:
Shakespeare’s portrait of a great tragic hero, whose fate was linked to black magic and fuelled by the fire of greed and ambition, bears little resemblance to the historical figure. Duncan (1034-40) was not Shakespeare’s venerable, elderly monarch, but a young king who was killed in battle, possibly by Macbeth, although this is not certain. We do know that Duncan was not murdered in the home of a so-called host.
Macbeth, King of Moray, was elected King of Scotland in place of Duncan’s son Malcolm, who was only a child, and for 14 years Macbeth is believed to have ruled equably, imposing law and order and encouraging devout Christianity. In 1050 he is known to have travelled to Rome for a Papal Jubilee. He was also a brave leader and made successful forays over the border into Northumbria, England.
In 1054, Macbeth was challenged by Siward, Earl of Northumbria, who was attempting to return Malcolm (later Malcolm III) to the throne. It was not until 1057 that Macbeth was killed and not by MacDuff but in battle at Lumphanan. The battle of Dunsinane and the encampment in Birnam Wood referred to in Shakespeare’s tragedy are both earlier events. The final battle was probably not between armies, but between two champions – Macbeth, who was middle-aged or even elderly, and Malcolm, still a young man. The two fought in a stone circle near Lumphanan where Malcolm triumphed. It was Malcolm, not Macduff, who beheaded Macbeth.
