Ahmad ibn Tulun
Al-Qata'i ("The Quarters") was established by Ahmad ibn Tulun when he was sent to Egypt by the Abbasid caliph to assume the governorship in 868 CE. Ibn Tulun arrived with a large military force that was too large to be housed in al-Askar. The city was founded on the Gabal Yashkhur, a hill to the northeast of the existing settlements that was said to have been the landing point for Noah's Ark after the Deluge, according to a local legend.
