Eventually the Tunjur began marrying amongst the Fur people producing Sultan Dali, a celebrated figure in Darfur histories, who was on his mother's side a Fur, and thus brought the dynasty closer to the people it ruled. Dali divided the country into provinces, and established a penal code, which, under the title of Kitab Dali or Dali's Book, is still preserved, and differs in some respects from Quranic law. His grandson Suleiman (or "Sulayman", usually distinguished by the Fur epithet Solon, meaning "the Arab" or "the Red") reigned from 1603 to 1637, and was a great warrior and a devoted Muslim. Suleiman Solon is considered as the founder of the Keira dynasty and the sultanate of Darfur. During the 17th century, the Keira sultans introduced the feudal "hakura" system into Darfur.
