Capulet is the head of the Capulet house, father of Juliet and uncle of Tybalt. The play shows him protecting his daughter's will in one scene and threatening her with the street and hunger in another.
In Act I, scene 1, he arrives at the brawl asking for his long sword, and his wife tells him he needs a crutch; the Prince threatens him with death, as he does Montague, if the peace is broken again. In scene 2, he tells Paris that Juliet is too young and that he should win her: "my will is but part of her consent." At the ball (scene 5), he restrains Tybalt, who wants to kill Romeo, and says Verona is proud of the young man, without imagining what is passing between him and his daughter.
In Act III, scene 4, without having spoken to Juliet, he sets the wedding with Paris for Thursday. In scene 5, when his wife tells him she refuses, he explodes: he orders his daughter to go to church on Thursday or never look him in the face again, and says that if she is not his, she may beg, starve, and die in the street. He orders the Nurse to be silent. In Act IV, scene 2, when Juliet, on her knees, feigns obedience, he hastens the wedding and says: "my heart is wondrous light, since this same wayward girl is so reclaimed."
On the wedding morning, he finds his daughter cold and says: "Death is my son-in-law, death is my heir" (Act IV, scene 5). In the tomb, he sees his daughter dead with the dagger and says the dagger was mistaken, holds out his hand to Montague, who promises a golden statue of Juliet, and replies that Romeo's will be equally rich (Act V, scene 3).
