Saharan oceans and bridges, barriers and divides in Africa's historiographical landscape

Based on a broad assessment of the scholarship on North-Western Africa, this article examines Saharan historiography with a particular view towards understanding how and why historians have long represented the continent as being composed of two ‘Africas’. Starting with the earliest Arabic writings, and, much later, French colonial renderings, it traces the epistemological creation of a racial and geographic divide. Then, the article considers the field of African studies in North African universities and ends with a review of recent multidisciplinary research that embraces a trans-Saharan approach.
