A blood feud is a cycle of retaliatory violence, with the relatives of someone who has been killed or otherwise wronged or dishonoured seeking vengeance by killing or otherwise physically punishing the culprits or their relatives. Historically, the word vendetta has been used to mean a blood feud. The word is Italian, and originates from the Latin vindicta (vengeance). In modern times, the word is sometimes extended to mean any other long-standing feud, not necessarily involving bloodshed. In literature, a famous example of a blood feud is Shakespeare’s Romeo and Juliet, centred on a blood feud between two families in Verona, Italy - Capulet and Montague.
