This Study aims to research the impact of Ibn Khaldun's phenomenon (who has gained a constant presence in the community of historians and reformists) on historians, philosophers, and sociologists in later eras, and the dedicated endeavor to demonstrate the characteristics of the work of such community members in the Modern Arab Renaissance Project, based on the history of Ibn Khaldun, his theorizations, approach, and vision, and through the following tracks: (Editing and Use). The Study also examines the historians and reformists’ perception of historical events in Ibn Khaldun's historical text and in the approach of his history based study to transfer them from the sphere of history and undertake an intimate effort of its interpretation so that it will be the force that achieves the desired reform. The importance of the Study is highlighted in the fruitful insight of historians and reformists of the Arab Maghreb to the text of Ibn Khaldun's history and to the text of his Al Muqaddimah/Introduction (Ibn Khaldun's Prolegomena), which tends to emphasize the distinctive features of the text to encourage its use and utilization, and it is exactly what we can describe as the "Possession of Historical Knowledge" and its use in an effective way. These historians and reformists are intimately cognizant of the importance of Ibn Khaldun's historical text and its introduction, and the importance of conjuring them up to reproduce them according to an ideology that expresses their intellectual propensity.
