Mamluc, plur. Mamalic, is defined by Pocock (Prolegom. ad Abulpharag. p. 7), and D'Herbelot (p. 545),
servum emptitium, seu qui pretio numerato in domini
possessionem cedit.
They frequently occur in the wars of Saladin (Bohadin, p. 236, etc.); and it was only the Bahartie Mamalukes that were first introduced into Egypt by his descendants.
