Macbeth is a tragedy about a Scottish nobleman who is consumed by ambition and driven to murder. After receiving a prophecy from three witches that he will become king, Macbeth, encouraged by his wife, kills King Duncan and takes the throne. However, guilt and paranoia take over, leading him to commit more murders to secure his power. As his tyranny grows, enemies rise against him, and his once-loyal allies turn away. In the end, Macbeth is defeated in battle by Macduff, and order is restored as Malcolm, Duncan’s son, becomes the rightful king.
