By the late 9th century, the Abbasid caliphate began to fracture as various regions gained increasing levels of autonomy. Across North Africa, Persia, and Central Asia emirates formed as provinces broke away. The monolithic Arab empire gave way to a more religiously homogenized Muslim world where the Shia Fatimids contested even the religious authority of the caliphate. By 1055 the Seljuq Turks had eliminated the Abbasids as a military power, nevertheless they continued to respect the caliph's titular authority.[82] During this time expansion of the Muslim world continued, by both conquest and peaceful proselytism even as both Islam and Muslim trade networks were extending into sub-Saharan West Africa, Central Asia, Volga Bulgaria and the Malay archipelago.[2]
The Golden Age saw new legal, philosophical, and religious developments. The major hadith collections were compiled and the four modern Sunni Madh'habs were established. Islamic law was advanced greatly by the efforts of the early 9th century jurist al-Shafi'i; he codified a method to establish the reliability of hadith, a topic which had been a locus of dispute among Islamic scholars.[83] Philosophers Ibn Sina (Avicenna) and Al-Farabi sought to incorporate Greek principles into Islamic theology, while others like the 11th century theologian Abu Hamid al-Ghazzali argued against them and ultimately prevailed.[84] Finally, Sufism and Shi'ism both underwent major changes in the 9th century. Sufism became a full-fledged movement that had moved towards mysticism and away from its ascetic roots, while Shi'ism split due to disagreements over the succession of Imams.[85]
The spread of the Islamic dominion induced hostility among medieval ecclesiastical Christian authors who saw Islam as an adversary in the light of the large numbers of new Muslim converts. This opposition resulted in polemical treatises which depicted Islam as the religion of the antichrist and of Muslims as libidinous and subhuman.[86] In the medieval period, a few Arab philosophers like the poet Al-Ma'arri adopted a critical approach to Islam, and the Jewish philosopher Maimonides contrasted Islamic views of morality to Jewish views that he himself elaborated.[87]
