Wahhābīsm is a religious-political movement that emerged in a definite section of history, in a specific geography, nourished by a distinctive cultural and social structure and which had considerable effects in the Islamic world. This historical phenomenon, which has religious, sectarian, social, and political dimensions, has been the subject of many works. Osman b. Bishr Najdī’s (1290/1873) ʿUnwān al-Majd fī Tārīkh Najd and Ahmed Cevdet Pasha’s (1313/1895) Tarih-i Cevdet, are two sources that come to mind on this subject. Ahmed Cevdet Pasha and Osman b. Bishr were historians who lived during roughly the same periods and dealt with events occurring during these times. The fact that both are representative of a particular discourse has inspired this study. A comparison between these two historians will be an impressive example in terms of revealing how social value judgments as well as the author’s own social contexts can affect the understanding of events. The study focused on the relationship between the text and the author, based on a comparative analysis method. This study will attempt to exemplify the approaches of these two historians, considered spokespersons of the discourse they represent, on the ways in which they convey social, historical and political events through the phenomenon of Wahhābīsm.
