Question: why do tybalt and romeo fight?
Answer: In Act III, Scene 1 of Romeo and Juliet, Tybalt is looking for Romeo to fight him for attending the Capulet ball uninvited. Because the Capulets and Montagues are in a family feud, Romeo “crashing” the party is disrespectful and forbidden. ... Because Romeo has just lost his best friend, he fights and kills Tybalt.
