In the play Macbeth by William Shakespeare, masculinity is a recurring theme. The play explores various aspects of masculinity like bravery, loyalty, and honor through characters like Banquo and Macduff and using Macbeth and Lady Macbeth to demonstrate a more destructive and toxic approach to masculinity. At the beginning of the play, Macbeth is brave, loyal and respected. But his ambition to become king changes his idea of masculinity to one of strength, ambition and ruthlessness. Lady Macbeth takes an even more aggressive approach to masculinity, and pushes Macbeth into the murder of King Duncan and his own friend, Banquo. As the story unfolds, we see Macbeth's transformation from an honorable man to being a ruthless and power hungry tyrant.
