re; Darfurian Roots
.Islam was a state cult in Dar Fur from the 17th century. Most likely , Islam come to Dar Fur from west , because the region was part of the medieval Kanem-Bornu empire , which was formaly Islamic from the 11th century if not earlier . Nilocentric historians have tended to assume that Islam reached Dar Fur from the Nile Valley but there is much evidence to sugges that it is not the case .
