It is assumed that the Montagues and the Capulets loathed each other because both families desired to be the most influential in Verona. Shakespeare’s classic drama “Romeo and Juliet” never fully explains the cause of the quarrel, though it is supposed that it lasted for many years.
One possibility for the family feud is betrayal by the other family. In addition, stories spread to other households in the city. Unfortunately, the war between the Montagues and Capulets does not end until Romeo and Juliet commit suicide because their families could not accept their love.
