In the 15th century the Tunjur arrived in Darfur, where they established themselves in northern Jebel Marra and ruled simultaneously with the Daju for some time.[10] They eventually seized power entirely under unclear circumstances,[11] and the last Daju king, whose name is mostly given by the local traditions as Ahmad al-Daj,[12] fled to present-day Chad, where his successors ruled as sultans of Dar Sila.[13] The Dar Sila Daju place the migration in the early 18th century, but this would have been too late. Instead, Balfour Paul suggests the late 15th century as a more fitting date.[13]
