Perhaps of greater consequence was Ibrahim II's murderous destruction of the Arab aristocracy. It left the Ifriqiyan regiments broken at the top and demoralized. Shortly after the departure of the bulk of the Ifriqiyan army for Ibrahim's last mad campaign in Italy in 902, the Kutama, a Berber tribe of the Petite Kabylie, fired up and organized by the Ismaili preacher Abu 'Abdullah al-Shi'i, burst out of their highland strongholds and began capturing the Aghlabid fortresses that had hitherto kept them contained. The crippled junds proved hardly an obstacle, and the Kutama would end up capturing all of Ifriqiya by 909 with relative ease, bringing the Aghlabid dynasty to an end, and inaugurating the Fatimid dynasty.
