"بين جبل الأوراس والواحات: ظهور وانتشار واختفاء الجماعات الاباضية بالزاب (ق 8- 9م/ ق 2- 3هـ)" – علاوة عمارة

After the widespread among the Pastoralist communities in Tripoli, Ibadism spread rapidly in the Aures and the oasis which were situated in the north of the Sahara. The Hawwâra, BaniBirzâl the Miknasa and BaniKimlân adopted this religious current, giving a birth of the Ibadit province called by the Arabic texts Zab. Nomadism, which was the dominated lifestyle in this area, favored the spread of this religious current and led to the integration of rural communities in the territory of the Imamate of Tahart. After a half century, however, the Ibadit communities ‘Zab’ reorganized into two rival branches the Wahbisme and Nukkârisme. This new situation coincided with the intensification of the propaganda activity of both Shi'ite and Sunni Maliki in the urban centers of Zab provoked a military response from Nukkârisme under the command of Abu Yazid. Threatened by the dynasties of the northern Maghreb, Ibadi communities were gradually pushed to the oases of the Sahara or disappeared from the stage. This loss of land was accelerated after the arrival of the BanuHilal, causing the formation of a new socio-religious map in the region.
