The prologue of Romeo and Juliet calls the title characters “star-crossed lovers”—and the stars do seem to conspire against these young lovers. Romeo is a Montague, and Juliet a Capulet. Their families are enmeshed in a feud, but the moment they meet—when Romeo and his friends attend a party at Juliet’s house in disguise—the two fall in love and quickly decide that they want to be married.
