Shakespeare's Sources and Real History
Ever wondered if Macbeth was a real person? He absolutely was, and his story is quite different from Shakespeare's version. Shakespeare primarily used Raphael Holinshed's Chronicles (1577) as his main source, but he cleverly mixed different historical accounts to create maximum dramatic impact.
The real Macbeth had a legitimate claim to the Scottish throne through Celtic tradition, which said the crown should alternate between family branches. When King Malcolm II died in 1034, he broke tradition by naming Duncan (his grandson) as heir instead of Macbeth (another grandson). Lady Macbeth (historically called Lady Gruoch) also had royal blood, being descended from two previous Scottish kings.
Unlike Shakespeare's version, the real Macbeth didn't sneak into Duncan's bedroom with a dagger. Instead, he raised an army, faced Duncan in open battle, and killed him in combat. Macbeth then ruled Scotland successfully for seventeen years - hardly the brief, guilt-ridden reign Shakespeare depicts.
Key Point: Shakespeare combined Macbeth's story with another tale about King Duff's murder to create the secretive, guilt-inducing assassination we see in the play.
