==== End of Zirid rule ====
During the 1130s and 1140s the Normans of Sicily began to capture cities and islands along the coast of Ifriqiya.{{Sfn|Abun-Nasr|1987|p=92}} [[Djerba|Jerba]] was captured in 1135 and Tripoli was captured in 1146. In 1148, the Normans captured Sfax, Gabès, and Mahdia.{{Sfn|Abun-Nasr|1987|p=92}}<ref name="Oman-2007"/> In Mahdia, the population was weakened by years of famine and the bulk of the Zirid army was away on another campaign when the Norman fleet, commanded by [[George of Antioch]], arrived off the coast. Al-Hasan decided to abandon the city, leaving it to be occupied, which effectively ended the Zirid dynasty's rule.{{Sfn|Tibi|2002|p={{page needed|date=April 2023}}}}{{sfn|Baadj|2015|p=35}} Al-Hasan fled to the citadel of al-Mu'allaqa near Carthage and stayed there for a several months. He planned to flee to the Fatimid court in Egypt but the Norman fleet blocked his way, so instead he headed west, making for the [[Almohad Caliphate|Almohad]] court of '[[Abd al-Mu'min]] in [[Marrakesh]]. He obtained permission from Yahya ibn al-'Aziz, the Hammadid ruler, to cross his territory, but after entering Hammadid territory he was detained and placed under [[house arrest]] in Algiers.{{Sfn|Tibi|2002|p={{page needed|date=April 2023}}}}{{sfn|Baadj|2015|p=35}} When 'Abd al-Mu'min captured Algiers in 1151, he freed al-Hasan, who accompanied him back to Marrakesh. Later, when 'Abd al-Mu'min conquered Mahdia in 1160, placing all of Ifriqiya under Almohad rule, [[Abu'l-Hasan al-Hasan ibn Ali|al-Hasan]] was with him.{{sfn|Baadj|2015|p=56-57}}{{Sfn|Tibi|2002|p={{page needed|date=April 2023}}}} 'Abd al-Mu'min appointed him governor of Mahdia, where he remained, residing in the suburb of Zawila, until 'Abd al-Mu'min's death in 1163. The new Almohad caliph, [[Abu Yaqub Yusuf|Abu Ya'qub Yusuf]], subsequently ordered him to come back to Marrakesh, but al-Hasan died along the way in [[Tamasna]] in 1167.{{Sfn|Tibi|2002|p={{page needed|date=April 2023}}}}<ref name="Bosworth-2004b" />
