They have no part in the action of the play, but they illustrate the family feud with the Capulets. Old Montague is still eager to draw his sword and join in the fighting.
Romeo.
Their only son. At the beginning of the play he thinks that he is in love with Rosaline, a lady whom we never see. It is the idea of being a lover that appeals to Romeo. He quickly forgets Rosaline when he meets Juliet. He is impulsive and passionate: he falls in love with Juliet and marries her. When his friend is killed by Juliet's cousin, Romeo avenges the murder " and as a punishment he is banished from his native city of Verona and his newly-married wife.
Benvolio.
One of Romeo's friends. He is quite a serious young man, who is sympathetic to Romeo's passions, and who allows Romeo and Mercutio to tease him. He is a necessary character rather than an interesting one: he is always available to offer an explanation.
Mercutio.
Romeo's other friend. He is full of energy, which is shown in the way he uses words, always playing with two or more meanings in a single word. His vitality leads him to challenge Tybalt, Juliet's cousin, to fight a duel. In the fighting, Mercutio is killed.
Capulet Household.
Old Capulet and Lady Capulet.
These two characters, the parents of Juliet, are more important than their counterparts, Romeo's parents. Old Capulet is anxious for his daughter to make a good marriage, but he is also " at the beginning of the play " insistent that she should love the man she marries. After the death of his nephew Tybalt, Old Capulet changes in his attitude to Juliet's marriage, and is prepared to force her to marry the man of his choice, Paris.
Lady Capulet is an obedient wife: she puts her husband's will before her daughter's wishes.
Juliet.
Their only child; we learn that other children have been born to the Capulets, but they have died. Juliet is almost fourteen years old. When the play opens she has never thought about marriage, but she is prepared to obey her parents and look with favour on the man they have chosen for her husband, the County Paris.
