Unrest in the East
After the death of Caliph al-Amin in 812 CE he was succeeded by al-Abbas ibn Musa ibn Isa ibn Musa ibn Muhammad ibn Ali ibn Abdallah ibn al-Abbas; he chose al-Hakim as his regnal name. The following shura, like the previous few, was unanimous in appointing the second heir that was preferred by the Banu Isa branch of the family;[1] this time it was Abu Ishaq Muhammad ibn Harun ibn Abu Abdallah Muhammad ibn al-Mansur [OTL Caliph al-Mu’tasim]. Since the end of the Fourth Fitna it had been discovered that Abu Abdallah Muhammad was attempting to surrender when he was murdered by his own soldiers. Thus his reputation had been rehabilitated somewhat and his surviving family had been treated with dignity. Electing the man’s grandson to the position of second heir was one of the ways in which the victors of the civil war attempted to heal the wounds of the conflict. Such leniency had not been extended to the Banu Salih however.
Soon after the shura dissolved reports of unrest emerged from across the eastern provinces of the caliphate. In Azarbayjan, Jibal, and Khurasan protesters, some of whom were armed, swarmed government buildings and demanded justice from the new khalifah. Against the advice of his advisors and the new wazir, Yahya ibn Khalid al-Baramika had since died and been succeeded by his protégé al-Fadl ibn Sahl ibn Zadanfarrukh, Caliph al-Hakim travelled to Azarbayjan to meet with the protesters himself. When he arrived he saw that they were a diverse crowd: peasants, artisans, the urban poor, and even some nobility and landowners. Furthermore, the protesters comprised both Muslims and dhimmi as well. Their complaints were diverse but they all had one theme in common: Ali ibn Isa ibn Mahan. The protests in the other provinces were of a similar composition and concerned similar issues. The man in question was a prominent member of the abna al-dawla and had at one time or another been the wali of each of the three provinces; at the time of the unrest he was the governor of Khurasan. The caliph was inclined to lend credence to the complaints but, as Ali ibn Isa ibn Mahan had rendered great service during the recent civil war, he needed to proceed cautiously.
Caliph al-Hakim set up a temporary court at Ardabil and invited the leaders of the protest movement to present their complaints formally. Their chosen spokesperson was al-Hasan ibn Abdallah, leader of a heterodox Zoroastrian community, owner of recently-inherited land near Ardabil, and known to his followers as Babak. He laid out the charges against Ali ibn Isa ibn Mahan as follows: taxes were exorbitant, to the extent that people couldn’t afford to pay them; the taxes collected enriched Ali and his household, rather than being spent on investments for the improvement of the province; Ali and his administrators appropriated people’s belongings without adequate compensation; land and property was also appropriated from the locals by Arab colonists without adequate compensation; and Ali refused to recruit local men into the army. Al-Hakim agreed that these were serious charges and promised to bring Ali ibn Isa ibn Mahan to justice. The bureaucrats accompanying the khalifah recorded all of the happenings of the court as part of their case against Ali ibn Isa ibn Mahan. Afterwards al-Hakim and his entourage travelled to Jibal, where the situation was much the same. Once again the caliph formally heard the complaints against the former governor and then moved on to Khurasan.
The unrest in Khurasan had escalated since the first reports had reached Caliph al-Hakim. In response to Ali ibn Isa ibn Mahan arresting and executing a number of protesters, the rest withdrew from the provincial capital of Merv to the region of Badghis, where they began arming themselves under the joint leadership of Hamza ibn Adharak, the sons of Asad ibn Saman, and Rafi ibn al-Layth. The former two were of local dihqan origin, while the latter was the grandson of Nasr ibn Sayyar al-Laythi al-Kinani, the last Umayyad governor of Khurasan. Caliph al-Hakim arrived at Merv and immediately enumerated the charges against the governor. Ali ibn Isa ibn Mahan pled innocence however and instead attempted to deflect from the accusations by claiming that the province was in the throes of a Kharijite revolt. Disgusted with Ali’s insolence al-Hakim ordered the soldiers at the gubernatorial court to arrest him; they momentarily hesitated but ultimately complied. The rest of Ali ibn Isa ibn Mahan’s family and household were imprisoned, while soldiers confiscated all of his ill-gotten wealth. The rebels were granted an unconditional pardon and guarantee of safety; their leaders returned to Merv to parlay with the khalifah. Al-Hakim had the charges against Ali ibn Isa ibn Mahan officially recorded, after which the wali was officially deposed and sent to Baghdad for indefinite imprisonment.
In Ali ibn Isa ibn Mahan’s place as governor of Khurasan was appointed al-Hakim’s son and first heir Abdallah. The new wali ingratiated himself immediately with the province’s elite who had previously been mistreated, by appointing the rebel leaders to important positions within his administration: Rafi ibn al-Layth was named as the sahib al-shurta (head of the police); the sons of Asad ibn Saman were posted as governors of the major towns (Nuh to Balkh, Yahya to Nishapur, Ilyas to Herat, and Ahmad to Merv al-Rudh); and Hamza ibn Adharak was given charge of the ghuzat who regularly raided the recalcitrant dhimmi tributary rulers of the eastern reaches of Khurasan. The news of the arrest and deposition of an abna al-dawla governor, the wali of Khurasan no less, sent shockwaves throughout the Abbasid Caliphate. Some governors and amirs, like Harthama ibn A’yan who strived for efficient and fair rule,[2] agreed with Caliph al-Hakim’s actions when the affair was publicised. There were others however who strongly promoted the interests of the abna al-dawla as a whole and saw this episode as an attack on their privileges. Combined with the integration into the military of newly-converted Iranian aristocrats, some argued quietly that the Abbasid dynasty was beginning to disregard those who had brought them to power.
