DEADLY-FEUD, in English law-books, a profession of irreconcileable enmity, till a person is revenged by the death of his enemy. The word feud is derived from the German Feud; which, as Hottoman observes, signifies modo bellum, modo capitales inimicitias*. Such enmity and revenge were allowed by law in the time of the Saxons, viz. If any man was killed, and a pecuniary satisfaction was not made to the kindred, it was lawful for them to take up arms and revenge themselves on the murderer; which was called deadly feud. And this probably was the original of an APPEAL.
