Duncan I of Scotland was born in approximately 1001 and became king in 1034.
69 years old.
he didnt do anything because he was a terrible king and he should have never became king.
you really should read the play, Macbeth becomes king
he was 8 years old when he became king
he was 18 when he became king
he was 13 when he became king (:
Macbeth initially thought positively of King Duncan and admired his leadership. However, his ambition and the witches' prophecy led him to consider harming Duncan in order to become king himself. Ultimately, Macbeth's thoughts towards Duncan became twisted as he plotted his murder.
I think he was eight years old when he became king
the king that became king at 9 years old was King Tut
He says he was overcome with rage because they had killed Duncan.
At the end of Shakespeare's play Macbeth; Malcolm, son of Duncan is proclaimed to be King of Scots. (In actual history, Macbeth was succeeded by his son Lulach; who was then was assassinated and deposed by Malcolm)
