throughout the government. He also sought to test the Fatamid ruler Al-Adid by publicly disrespecting him through actions, such as riding his horse into the courtyard of the Caliph's palace (something only the caliph was allowed to do). Clearly feeling secure in Egypt Saladin undertook attacks against the Kingdom of Jerusalem in 1170 and succeeded in taking the strategic town of Ayla. He withdrew early from the 1171 campaign, which was supposed to be an assault on the Crusader fortress of Karak with Nur al-Din Zangi, partially because he wanted to avoid meeting his master and officially due to the death of his father. Nur al-Din was displeased with these actions and viewed Saladin after Ayyoub's death (Ayyoub was greatly trusted by Nur al-Din and oversaw Egypt's finances on his behalf). In order to reign in his vassal and gain favor with the Abbasid Caliph, Nur al-Din commanded Saladin to overthrow the Fatimid Dynasty in June 1171. Unwilling to take more revolts, Saladin waited until Al-Adid's timely death (many suspected that al-Adid was in fact poisoned by Saladin, probably) to officially end the dynasty of the Fatamids, which he did on September 17, 1171 by having the Friday sermons across Egypt said in the name Al-Mustadi, the Abbasid caliph. Social Though he did not disband the Fatimid Caliphate until 1171 Saladin actively sought to spread Sunnism as soon as he became the vizier. He established numerous mosques and madrasah in order further the spread of Sunni beliefs. This move was extremely popular amongst the majority Sunni population and by systematically appointing Sunni jurists to legal positions throughout the state Saladin tactfully eliminated any opposition he might encounter from the religious establishment when attempting to disband the Fatimid Caliphate. Another hallmark of Saladin's effective rule was his willingness to accept useful Egyptian elites into his administration. None of these were more important than Qadi al-Fadil, a brilliant jurist from Ascalon, who had served Shawar and briefly Shirkuh before coming into the service of Saladin. Men like Qadi al-Fadil provided Saladin with the more than just their ample skills, but also with direct connections into the complicated social/political circles that held power in the Fatimid State. Finally, Saladin's famed tolerance towards non-Muslims emerged when he allowed the Coptic Christians and Jews, who were deeply ingrained into Egypt's highly successful financial system, to retain their posts. This move secured the continued success of
