The early years of the Abbasid Caliphate not only marked a time of tremendous economic and political growth but this period also introduced a renewed sense of hope to the Muslim community. During these first few decades, Baghdad flourished into a bustling center of international trade, and many non-Arabs found themselves in a more inclusive society that valued piety and legal equality over old policies that had previously favored an Arab elite. For many Muslims who had suffered under the corruption and chaos of the Umayyad regime, the Abbasid revolution represented a movement that sought to establish a different, more pious Islamic state.
However, towards the end of the 8th century, signs of declining caliphal authority began to manifest. This steady deterioration of consolidated power continued for much of the Abbasid empire, which allowed for the rise of many political movements in its absence. In Baghdad, the Abbasid government had developed both a complex hierarchical bureaucracy and an elaborate court life. As a result, each caliph became more withdrawn from his subjects than the previous one. By the start of the 9th century, the caliph Harun al-Rashid rarely interacted with the common people, and disdain towards the caliph’s lavish private life emerged within the Muslim community. His death then provoked a decade long civil war between his two sons over who would succeed. This war greatly damaged Baghdad, the symbolic seat of the Abbasid caliphate. The culmination of these factors and ongoing internal struggle within the military throughout the 9th century irreparably weakened the Abbasid caliph’s authority and enabled many political movements throughout the Islamic world to gain a significant amount of autonomy. Some scholars argue that almost all of these movements established legitimacy in some relation to the authority of the Abbasid caliphs. However, at the time that many of these political movements began to gain prominence, the caliph no longer held the same position of authority as he had before, and any power the caliph still maintained was restricted to the boundaries of Baghdad. While some groups, like the Buyids and the Seljuks, manipulated the caliph to gain power over the Abbasid state, most independent political movements exploited this lack of central authority as an opportunity to establish legitimacy through various political strategies and religious justifications.
Many smaller dynasties found a certain degree of autonomy during the 9th century when problems in Baghdad captured much of the central government’s attention. Although these groups technically remained loyal to the Abbasids, they no longer obeyed the state’s laws or expectations. Egypt, governed at the time by Ahmad ibn Tulun, established an independent regime that remained autonomous for much of the 9th century. In Khorasan and some parts of Afghanistan, the Tahirids and Saffarids continued to govern their territories on behalf of the Abbasid Caliphate. However, in reality, these dynasties functioned autonomously and only occasionally sent revenue to the capital. By the time of the Buyids, the Samanids in Khorasan refused to send any money at all. The only traces of Abbasid loyalties in the Samanid dynasty lied in the khutba, when the local religious leader would being prayer in the name of the Abbasid caliph. Other groups, such as the Shi’ite Hamdanid Confederation, took advantage of this decline in central authority to expand by seizing control of cities and their resources. While these small dynasties never explicitly opposed the Abbasids, their legitimacy did not depend on the support of the caliph, but rather they established autonomy at a time when the authority of the Abbasid caliphs was almost absent in certain regions.
The decaying authority of the Abbasid caliphs throughout much of the 8th and 9th century eventually lead to the Buyid capture of Baghdad in 945, which permanently disrupted traditional notions of the caliph’s role in the Islamic state. From the early days of Islam, the leader of the Muslim community provided both religious and political guidance to the people, and despite the political and economic crises that generally characterized the first few centuries of the Abbasid caliphate, this dual authority persisted. However, when Ahmad and ‘Ali conquered Baghdad, the Buyids took political control of the state and recognized the caliph as only a spiritual figure. Not only did the Buyids delegitimize the caliph by adopting titles, such as “Commanders of the Commanders” and “King of Kings,” but the reality that a Shi’ite dynasty now controlled the Sunni caliph significantly harmed the people’s perception of the caliph as their leader. This move to redefine the caliph’s role in the Islamic state as only a spiritual one dramatically damaged, if not totally eliminated, caliphal authority outside of Baghdad.
While the Buyids controlled Abbasid state policies, their sphere of influence was essentially limited to the city of Baghdad, and consequently, the rest of the Islamic state, particularly the regions further from the capital, experienced little pressure from the caliph and the central government. During this time, many political movements rose in response to this gap in consolidated leadership.
