Rise of the Abbasid Empire (c. 750 CE)

The Umayyad dynasty was overthrown by another family of Meccan origin, the Abbasids, in 750 CE. The Abbasids distinguished themselves from the Umayyads by attacking their moral character and administration. In particular, they appealed to non-Arab Muslims, known as mawali, who remained outside the kinship-based society of the Arabs and were perceived as a lower class within the Umayyad empire. The Abbasid dynasty descended from Muhammad’s youngest uncle, Abbas ibn Abd al-Muttalib (566–653 CE), from whom the dynasty takes its name. Muhammad ibn ‘Ali, a great-grandson of Abbas, began to campaign for the return of power to the family of Muhammad, the Hashimites, in Persia during the reign of Umar II, an Umayyad caliph who ruled from 717–720 CE.

Power in Baghdad

The Abbasids moved the empire’s capital from Damascus, in modern-day Syria, to Baghdad, in modern-day Iraq, in 762 CE. The Abbasids had depended heavily on the support of Persians in their overthrow of the Umayyads, and the geographic power shift appeased the Persian mawali support base. Abu al-‘Abbas’s successor, Al-Mansur, welcomed non-Arab Muslims to his court. While this helped integrate Arab and Persian cultures, it alienated the Arabs who had supported the Abbasids in their battles against the Umayyads. The Abbasids established the new position of vizier to delegate central authority, and delegated even greater authority to local emirs. As the viziers exerted greater influence, many Abbasid caliphs were relegated to a more ceremonial role as Persian bureaucracy slowly replaced the old Arab aristocracy.

The Abbasids, who ruled from Baghdad, had an unbroken line of caliphs for over three centuries, consolidating Islamic rule and cultivating great intellectual and cultural developments in the Middle East in the Golden Age of Islam. By 940 CE, however, the power of the caliphate under the Abbasids began waning as non-Arabs gained influence and the various subordinate sultans and emirs became increasingly independent.

Decline of the Abbasid Empire

The Abbasid leadership worked to overcome the political challenges of a large empire with limited communication in the last half of the 8th century (750–800 CE). While the Byzantine Empire was fighting Abbasid rule in Syria and Anatolia, the caliphate’s military operations were focused on internal unrest. Local governors had begun to exert greater autonomy, using their increasing power to make their positions hereditary. Simultaneously, former supporters of the Abbasids had broken away to create a separate kingdom around Khorosan in northern Persia.

Several factions left the empire to exercise independent authority. In 793 CE, the Shi’a (also called Shi’ite) dynasty of Idrisids gained authored over Fez in Morocco. The Berber Kharijites set up an independent state in North Africa in 801 CE. A family of governors under the Abbasids became increasingly independent until they founded the Aghlabid Emirate in the 830s. Within 50 years, the Idrisids in the Maghreb, the Aghlabids of Ifriqiya, and the Tulunids and Ikshidids of Misr became independent in Africa.

By the 860s governors in Egypt set up their own Tulunid Emirate, so named for its founder Ahmad ibn Tulun, starting a dynastic rule separate from the caliph. In the eastern territories, local governors decreased their ties to the central Abbasid rule. The Saffarids of Herat and the Samanids of Bukhara seceded in the 870s to cultivate a more Persian culture and rule. The Tulinid dynasty managed Palestine, the Hijaz, and parts of Egypt. By 900 CE, the Abbasids controlled only central Mesopotamia, and the Byzantine Empire began to reconquer western Anatolia.

The Fatimid Caliphate (909–1171 CE)

Several factions challenged the Abbasids’ claims to the caliphate. Most Shi’a Muslims had supported the Abbasid war against the Umayyads because the Abbasids claimed legitimacy with their familial connection to Muhammad, an important issue for Shi’a. However, once in power, the Abbasids embraced Sunni Islam and disavowed any support for Shi’a beliefs.

The Shiʻa Ubayd Allah al-Mahdi Billah of the Fatimid dynasty, who claimed descent from Muhammad’s daughter, declared himself Caliph in 909 CE and created a separate line of caliphs in North Africa. The Fatimid caliphs initially controlled Morocco, Algeria, Tunisia, and Libya, and they expanded for the next 150 years, taking Egypt and Palestine. The Abbasid dynasty finally challenged Fatimid rule, limiting them to Egypt. By the 920s, a Shi’a sect that only recognized the first five Imams and could trace its roots to Muhammad’s daughter Fatima, took control of Idrisi and then Aghlabid domains. This group advanced to Egypt in 969 CE, establishing their capital near Fustat in Cairo, which they built as a bastion of Shi’a learning and politics. By 1000 CE, they had become the chief political and ideological challenge to Abbasid Sunni Islam. At this point, the Abbasid dynasty had fragmented into several governorships that were mostly autonomous, although they official recognized caliphal authority from Baghdad. The caliph himself was under “protection” of the Buyid Emirs, who possessed all of Iraq and western Iran, and were quietly Shi’a in their sympathies.

Outside Iraq, all the autonomous provinces slowly became states with hereditary rulers, armies, and revenues. They operated under only nominal caliph authority, with emirs ruling their own provinces from their own capitals. Mahmud of Ghazni took the title of “sultan,” instead of “emir,” signifying the Ghaznavid Empire’s independence from caliphal authority, despite Mahmud’s ostentatious displays of Sunni orthodoxy and ritual submission to the caliph. In the 11th century, the loss of respect for the caliphs continued, as some Islamic rulers no longer mentioned the caliph’s name in the Friday khutba, or struck it off their coinage. The political power of the Abbasids largely ended with the rise of the Buyids and the Seljuq Turks in 1258 CE. Though lacking in political power, the dynasty continued to claim authority in religious matters until after the Ottoman conquest of Egypt in 1517.
