The tragedy of Macbeth by William Shakespeare tells the story of the Scottish general Macbeth, who is convinced by the prophecies of three witches and his ambitious wife Lady Macbeth to murder King Duncan and take the throne. This disrupts the natural order and leads to chaos. As Macbeth commits more murders to hold onto power, he becomes increasingly troubled. In the end, Macduff helps Malcolm defeat Macbeth and restore order, demonstrating that power does not necessarily lead to happiness.
