Shakespeare's source for the story is the account of Macbeth, King of Scotland; Macduff; and Duncan in Holinshed's Chronicles (1587), a history of England, Scotland, and Ireland familiar to Shakespeare and his contemporaries, although the events in the play differ extensively from the history of the real Macbeth. The events of the tragedy are usually associated with the execution of Henry Garnet for complicity in the Gunpowder Plot of 1605.
