The document provides background information on Shakespeare's Macbeth, including its appeal to Elizabethan audiences, historical inaccuracies about the real King Macbeth, and how it served as a tribute to the new King James I. It summarizes that Shakespeare wrote Macbeth in 1606 during King James' reign, setting it in Scotland but making Banquo, not Macbeth, an ancestor of James to avoid making the protagonist a villain. It also discusses how themes of witchcraft would have entertained James, who considered himself an expert on the topic.
