Having overthrown the Umayyad caliphs, the Abbasid rulers moved east, establishing a capital at Baghdad. There the ruling elite were able to foster a time of immense creativity and intellectual achievement that allowed cultures, languages, and ethnicities to blend in the course of building an empire. The Abbasid Caliphate kept intact the Persian and Byzantine administrative apparatus, which ensured wealth for the elite and promoted the revival of cities and trade. While Arabic continued as the language of administration and religion, Persian language and literary forms also began to influence Arabic and helped to create a rich tradition of both secular and religious works, housed at the Great Library of Baghdad. The caliphate became cosmopolitan. Syriac Christians translated Greek works into Arabic, Persians served as administrators, and Jewish people and Christians alike were bankers and physicians. Wealth flowed in from the trading routes that connected the Mediterranean with India and China, and Baghdad became the center of the empire, a cosmopolitan city with a reputation as a place of learning, commerce, and trade. (Figure 13.11) Figure 13.11 This map shows the Abbasid Caliphate in 850, with areas listed either by their regional name in Arabic or by the ruling dynasty. The caliphate stretched from the territory in North Africa held by the Aghlabids in the west to the region of Transoxiana in the east. The heartland was in Iraq in the center.

Other problems went unresolved, however, and new ones arose that the Abbasid rulers struggled to manage. To create an army that was loyal solely to the Abbasid ruler, early ninth-century caliphs began to use enslaved men of Turkic origins. These soldiers, called mamluks, were often young boys taken from their homes, converted to Islam, and trained as soldiers. Their education was provided and their social status assured; in return, they were expected to be loyal to the caliph alone. The mamluks were initially useful for quelling rebellions, attacking Byzantine rivals, and enabling caliphs such as al-Mutasim to gain some security against hostile aristocrats. Al-Mutasim’s predecessors had tried to strike a balance between Persian and Arab elites, but his own power rested on the militaristic force of the mamluks. The wealth and favor shown the military, however, and especially to these Turkic soldiers, only served to erode the caliph’s position with the traditional elite. To solve this problem, al-Mutasim moved his capital from Baghdad to Samarra in northern Mesopotamia in order to segregate the Turkic soldiers from the rest of the population. After his death, the mamluks supported different successors in a vicious civil war that lasted nearly ten years. Their power and influence had become a permanent fixture in the Abbasid heartland. The Abbasid rulers also faced religious divisions and criticism, even as the cosmopolitan nature of the caliphate sparked the growth of speculative philosophy and rationalizing thought. For example, philosophers like al-Farabi and Ibn Sina delved deeply into the philosophy of the ancient Greeks, including their systems of logic and medicine. They promoted new ways of approaching philosophy and made contributions to science, law, and theology that later influenced the thought of Christian philosophers in Europe. These Islamic scholars translated ancient philosophical texts into Arabic that Christian scholars later translated into Latin. However, the fact that these two leading figures were not Arabs, and that they applied human reason to the truths of Islam, antagonized religious conservatives and fostered discontent with the worldly caliphs. The Abbasid cultural renaissance was a remarkable achievement, but the Abbasid leadership was not celebrated by all. One of the most important and enduring religious developments in the Abbasid period was the growth of a mystical form of Islam known as Sufism. Sufism was organized into “brotherhoods,” each of which followed the teachings and practices of its founders in the pursuit of heartfelt and personal worship of God. Sufis behaved like monks in other religions, renouncing the artificial performance of religious duties, as well as luxury and worldliness, to embrace a life dedicated to mystical union with God. Some Sufis also rejected the rationalization of religion and criticized the incorporation of Greek philosophy into Islamic theology. Though Sufism was not a political movement, its search for spiritual purity and rejection of classical philosophy weakened the position of the Abbasids. In Their Own Words Poetry from the Abbasid Period Omar Khayyam was a mathematician, philosopher, and poet who lived during the transition from Abbasid rule to the rise of the Seljuk Turks. He is famous for writing poetry that was often controversial in its day, so much so that he was accused of being irreligious at the Seljuk court. For example, drinking wine was forbidden by the Quran, but Khayyam often refers to drinking wine in terms that seem both literal and metaphorical. Other contemporaries viewed his poetry as reflecting the Sufi value of moving beyond external religious conformity to a more personal spirituality. Following are excerpts from his most famous work, The Rubaiyat. Khayyam uses imagery related to drinking to express both the joy of life and its fleeting nature. He also considers life experience more precious than formal education, showing a disdain for the teachings of sages and scholars. (Note: The word sans is French for “without,” and a muezzin is the person who makes the call to prayer five times a day at a mosque.)

In the lines of XXV, why does he chide “Saints and Sages?” What might be his issue with these wise or holy men? As the Abbasid rulers struggled to maintain control over the heartland in Mesopotamia and Persia, the political and cultural unity of the Islamic world began to decline. Dynasties that viewed the Abbasids as too corrupt or too distant began to splinter off. In Spain and North Africa, the Amazigh Idrisid dynasty in Morocco and the Aghlabids in Algeria drifted away from Abbasid control. On the eastern fringes, Persian and Turkic dynasties openly contested the authority of the Abbasid Caliphate without formally dissolving it. This process of growing disunity is called political devolution, in which powers once assumed by a centralized state are taken over by local authorities. The worldliness of the Abbasid culture offended religious conservatives. For example, the scholar al-Ghazali criticized the incorporation of Greek speculative thought when speaking of Islamic beliefs. The caliphs’ support for Persian culture and literature, as well as the power given to Persian families and scholars, alienated the Arab elites. An entrenched and powerful bureaucracy, as well as the use of the mamluks, made the Abbasid government look corrupt and weak. The most significant blow to Abbasid power was the ability of rivals to establish their own states and claim the title of caliph, as well as the arrival of powerful Turkic tribes like the Seljuks in the Abbasid heartland.
