Macbeth by Shakespeare is one of his most powerful plays, written in the early 1600s about events from the 11th century in Scotland. It explores themes of ambition, loyalty, and the battle between good and evil. The supernatural elements, especially the witches' prophecies that greatly influence Macbeth's actions, are also important. The play shows the battle between fate and free will, with fate ultimately stronger. Many believe the play is cursed due to Shakespeare using real witches' spells, so actors refer to it as "The Scottish Play" to avoid doom. It was first performed in 1606 for King James I, who had an interest in witches.
