The wazir al-Jarjarai died in 436, the year following the death of Anushtakin. His disappearance opened the way to an increase of faction fighting and court intrigue in Cairo. The next wazir was Ibn al-Anbari, who soon provoked the enmity of the Queen Mother. It seems that Abu Nasr, Saʿd ad-Dahir’s brother, was insulted by one of the wazir’s servants, and when Abu Nasr complained he only obtained a rough answer from the wazir. By the plots of Sʿad ad-Dahir and harim influence, Ibn al-Anbari was deposed and replaced by the renegade Jew, Abu Mansur Sadaqa, in whom the Queen expected to find a docile instrument. But Abu Saʿd continued his intrigues against Ibn al-Anbari, and finally secured his execution in 440. But this proved his undoing, for Sadaqa began to fear that the same fate might lie in store for him also, so he bribed the Turkish guard to assassinate Abu Saʿd, and Abu Nasr was put to death on the same day. In retaliation the Queen Mother procured the assassination of Sadaqa. The next wazir was a mere creature of the Queen and imported more negro troops in large numbers to counterbalance the Turkish guard, whilst the Khalif and his supporters brought in more Turks and had the wazir murdered. The next wazir held office only three months and then was deposed. For the six years following (436-442) the domestic politics of Egypt centered entirely in the struggle between the Turkish mercenaries and the negro troops. Then in 442 there came forward once more a capable wazir in the humble fisherman’s son al-Yazuri, as his name denotes a native of the coast village of Yazur, near Jaffa, and he held office more or less firmly for a period of eight years.
