The capture of Tahert occurred in 909 CE at the city of Tahert (present day Tagdemt) when the Fatimids led by Abu Abdallah al-Shi'i destroyed the city which resulted in the end of the Rustamid kingdom and the flight of the population into {{ILL|Sédrata (Ouargla)|fr}} near Ouargla, from where they would emigrate to Mzab in the 11th century.{{Cite book |last=Abun-Nasr |first=Jamil M. |url=http://archive.org/details/historyofmaghrib0000abun |title=A history of the Maghrib |date=1971 |publisher=Cambridge [Eng.] University Press |others=Internet Archive |isbn=978-0-521-07981-5 |pages=76}}{{Cite journal |last=Aillet |first=Cyrille |date=2016-06-01 |title=L’ibadisme maghrébin en contexte fatimide (début xe-milieu xie siècle) |url=https://journals.openedition.org/remmm/9467 |journal=Revue des mondes musulmans et de la Méditerranée |language=fr |issue=139 |pages=127–146 |doi=10.4000/remmm.9467 |issn=0997-1327|doi-access=free }}{{Cite journal |last=Love |first=Jr |last2=Love |first2=Paul M. |last3=Jr |date=2013 |title=Djerba and the Limits of Rustamid Power.
