Romeo and Juliet is Shakespeare's play in which two young people of Verona, children of enemy families, the Montagues and the Capulets, fall in love at a ball, marry in secret, and die in the Capulet tomb, and only these deaths bring peace between the parents.
In Act I, the Prologue already announces the death of the lovers. After a street brawl in which Prince Escalus threatens death to anyone who revives it (scene 1), Romeo, who suffers for Rosaline, goes masked to the Capulet ball, sees Juliet, and forgets the other. Tybalt recognizes the voice of a Montague and wants to kill him, but Capulet restrains him; it is through the Nurse that each discovers the other belongs to the enemy house (scene 5).
In Act II, the two swear love in the garden (scene 2), and Friar Laurence marries them the next day (scenes 3 and 6). In Act III, Tybalt kills Mercutio, Romeo's friend; Romeo kills Tybalt and is banished (scene 1). Capulet arranges Juliet's marriage to Paris, she refuses, and her father threatens to disinherit her (scene 5).
In Act IV, the friar gives Juliet a potion that makes her appear dead for forty-two hours, and she drinks it alone (scene 3). In Act V, the letter that would warn Romeo does not arrive, because Friar John was locked in a house suspected of plague (scene 2). Romeo, who heard in Mantua that Juliet died, buys poison, returns to Verona, kills Paris, and drinks (scene 3). Juliet wakes and kills herself with his dagger, and Capulet and Montague seal the peace.
