If you examine the historic chart in the Historical Background section, you can see that it is Lady Macbeth, whose real name was Gruoch, who actually had the strongest claim to the throne to rival King Duncan’s. She had a young son, Lulach, and there were historic precedents for a woman taking the throne on behalf of her underage son. Scotland had no law barring women from succession to the throne. Write a piece of fiction in which there is no Macbeth, and Lady Macbeth challenges Malcolm for the throne herself.
