6 Of course, history existed before Ibn Khaldun in the sense of a written record of past events. Ancient writers such as Tacitus and Thucydides became famous for their historical accounts. It is also true that a sense of history as having a purpose existed before Ibn Khaldun. In fact, it is one of the basic premises of Christianity. See I. Khaldoun, Le voyage d’Occident et d’Orient.
