Like what Yusuf ibn Hasan, a chief of Tuggurt did in the era of the Hafsid Sultan Abu 'Amr Uthman, who was obliged to Subjugate the city two times, one in 1449 and another in 1465.

[3] The Sultanate was founded in the fifteenth century by the Banu Djellab, a dynasty whose exact origins remain obscure.

They claimed to be the last descendants of the Marinid dynasty, and thus modelled their court and ruling system, such as the use of a praetorian guard of black slaves, on that of the Moroccan sultans.

[4] According to the Encyclopedia of Islam, the founder was a certain Sulayman ibn Djellab, a Moroccan prince, related to the Marinid family, who after his return from the hajj founded a mosque in the region, and with the help of the local nomads, became recognised there as a ruler.

The Ben Djellab surrendered in the face of enemy artillery; politically they became vassals of Algiers and paid it tribute.
