How a decade of palace coups and military mutinies crippled the Abbasid Caliphate
Between 861 and 870, the Abbasid Caliphate descended into a period of extreme instability known as the Anarchy at Samarra. Four caliphs were violently deposed or murdered as rival Turkic military factions turned the throne into a puppet position, permanently eroding the central government's authority and prestige.
The crisis began in 861 with the assassination of Caliph al-Mutawakkil by his own Turkic guards. This act triggered a decade of chaos where military leaders dictated the succession, often installing and removing rulers at will. Al-Muntasir, who succeeded his father, reigned for only six months before dying under suspicious circumstances, possibly by poisoning. His successors, al-Musta'in, al-Mu'tazz, and al-Muhtadi, all struggled to reclaim power from the Turkic military chiefs who held the real influence in the capital of Samarra.
Financial insolvency was a primary driver of the instability. The Caliphate faced a severe revenue shortage, which prevented the state from paying its troops. At the accession of al-Mu'tazz in 866, the traditional donative of ten months' pay had to be slashed to just two. This inability to meet financial demands fueled constant unrest and civil war, including a conflict between Baghdad and Samarra that saw al-Musta'in exiled and eventually executed. Al-Mu'tazz, despite his efforts to exclude the military from civil administration, was ultimately deposed and killed in 869 after failing to satisfy the soldiers' demands.
The final ruler of this period, al-Muhtadi, attempted to restore order by adopting an austere, pious lifestyle and presiding personally over courts of grievances to win public support. However, his efforts to curb the power of the Turkic commanders led to his murder in June 870. The ascension of al-Mu'tamid and the rise of the faction around Musa ibn Bugha eventually brought the anarchy to a close. Yet, the damage was irreversible; the central government's weakness encouraged widespread secessionist tendencies, culminating in the brutal Zanj Rebellion, which claimed tens of thousands of lives and further fractured the empire.
