Ал-Мустағин: Аббасид халифасы (862-866)

12th Abbasid caliph (r. 862–866)

Abū al ʿAbbās Aḥmad ibn Muḥammad ibn Muḥammad (أبو العباس أحمد بن محمد بن محمد; 836 – 17 October 866), better known by his regnal title al Mustaʿīn (836 – 17 October 866) was the Abbasid caliph from 862 to 866, during the "Anarchy at Samarra". After the death of previous Caliph, al Muntasir (who had not appointed any successors), the Turkic military leaders held a council to select his successor. They were not willing to have al Mu'tazz or his brothers; so they elected Ahmad ibn Muhammad (أحمد بن محمد), a nephew of al Mutawakkil, who took the regnal name al Mustaʿīn bi ʾllāh (المستعين بالله "he who looks for help to God"). Arab and other troops based in Baghdad, displeased at the choice, attacked the assembly, broke open the prison, and plundered the armory. They were attacked by the Turkic and Berber soldiers, and after some fighting in which many died, succumbed. Baghdad had yet to learn that the Caliphate no longer depended on the opinions of the Arabians, but had passed into other hands.

Ahmad ibn Muhammad (future al Musta'in) was the son of Abbasid prince Muhammad ibn al Mu'tasim and his mother was a concubine from province of Sicily called Makhariq. Al Musta'in was the grandson of caliph al Mu'tasim (r. 833–842). He was the nephew of caliph al Wathiq (r. 842–847) and caliph al Mutawakkil (r. 847–861). His uncle, caliph al Mutawakkil (r. 847–861) had created a plan of succession that would allow his sons to inherit the caliphate after his death; he would be succeeded first by his eldest son, al Muntasir, then by al Mu'tazz and third by al Mu'ayyad. In December 861 al Mutawakkil was assassinated by a group of Turkic military officers, likely with the support of al Muntasir. During al Muntasir's short reign (r. 861–862), the Turks pressured him into removing al Mu'tazz and al Mu'ayyad from the succession. When al Muntasir died, the Turkic officers gathered together and decided to install the dead caliph's cousin al Musta'in on the throne.

The new caliph was almost immediately faced with a large riot in Samarra in support of the disenfranchised al Mu'tazz; the rioters were put down by the military but casualties on both sides were heavy. Al Musta'in, worried that al Mu'tazz or al Mua'yyad could press their claims to the caliphate, first attempted to buy them off and then threw them in prison. The governor of Baghdad persuaded the city to submit, and the succession was thereafter acknowledged throughout the land. Al Mu'tazz and his brother, threatened by the Turkic and Berber troops, resigned their titles to succeed, and were then, by way of protection, kept in confinement. After a second attempt to overturn the decision made by the Turks, al Mu'tazz and his brother would have been put to death, but the vizier intervened and saved their lives, for which act of mercy, his property was seized by the Turkic soldiers, and himself banished to Crete. The Empire, in fact, both at home and abroad, had passed into the hands of Turks. In 863, the Muslim campaign against the Christians was going badly. Two whole corps in Armenia and Asia Minor, some 8,000 strong, with their leaders, were killed during the Battle of Lalakaon. The tidings created anger and riots in Baghdad. The ancient cry for a Holy War rang through the streets. People blamed the Turks that had brought disaster on the faith, murdered their Caliphs, and set up others at their pleasure. With such cries the city rose in uproar; the prisons were broken into and bridges burned. But Baghdad could no longer dictate to its rulers; it could only riot. The fighting spirit was, however, strong enough to draw men from the surrounding provinces, who flocked as free lances to fight against the infidel. But the Turks cared for none of these things, nor did the Caliph. In 864, his forces put down a rebellion by the Alid Yahya ibn Umar and a revolt in Hims. In 865, the end for al Musta'in himself was now at hand. After some disagreements between the Turkish leaders that placed al Musta'in in much danger, he, along with two other Turkic leaders, Bugha al Sharabi (known as Bugha al Saghir) and Wasif al Turki, left Samarra on a boat to East Baghdad. The Turks sent after him a party of their captains, requesting him to return to Samarra. But the Caliph refused, and hard words followed between the two sides, in the heat of which one of the Turkic speakers received a blow. The insult rankled the Turkic officers, and on returning to Samarra, the Turkic troops rose together, and bringing forth al Mu'tazz from his confinement, saluted him as Caliph. Within a few weeks, his brother Abu Ahmad al Muwaffaq, with 50,000 Turks and 2,000 Berbers, besieged Baghdad, a siege that would last throughout the year 865.

As the siege of Baghdad wore on, it began to have its intended effect. Food and money slowly became scarce, and discontent among the populace began to emerge. As early as August, a group of members of the Abbasid family complained to Muhammad ibn 'Abdallah that their stipends were not being paid. As conditions in the city deteriorated, Muhammad gradually became convinced that victory through force of arms was impossible. By November at the latest, and without the knowledge or permission of al Musta'in, he had opened negotiations with al Mu'tazz regarding al Musta'in's surrender. Muhammad and al Mu'tazz had already started negotiating with each other when the former launched his failed sally. After the battle, al Mu'tazz criticized Muhammad for acting in bad faith, and the Samarran army intensified the siege. Soon the city was running low on resources. Crowds began appearing before Muhammad's palace, crying "hunger!" and demanding a resolution to their problems. Muhammad held off the crowds with promises, and at the same time sent an offer of peace to al Mu'tazz. This was responded to favorably, and beginning on December 8 a representative from Abu Ahmad's camp began meeting Muhammad in private to discuss how to end the conflict. As the siege progressed into December, the population of Baghdad became more agitated. On December 16, some of the regular infantry and commoners gathered together, with the former demanding their pay and the latter complaining about how food prices had skyrocketed. Muhammad was able to convince them to temporarily disperse, but riots broke out in the city two days later and it was only with difficulty that they were quelled. Meanwhile, negotiations between Muhammad and Abu Ahmad continued; emissaries were sent by Muhammad to Abu Ahmad's camp, and Samarran prisoners of war were released. Toward the end of December, a provisional agreement between the two sides to depose al Musta'in was reached, and Abu Ahmad sent five ships loaded with foodstuffs and fodder to relieve the shortages in the city. When the citizens of Baghdad learned that Muhammad had agreed to depose al Musta'in, they angrily assembled outside his palace. Out of loyalty to al Musta'in and fears that Muhammad's surrender could result in the Samarrans plundering the city, they attacked the palace gates and fought against the guards. In order to calm the protestors, al Musta'in appeared above the palace gate with Muhammad at his side, and he gave assurances to the crowd that he was still caliph and that he would lead the Friday prayers the next morning. The following day, December 28, he failed to appear; in response, the houses of Muhammad's subordinates were looted and a large crowd again approached Muhammad's palace, forcing al Musta'in to make another public appearance. Shortly after this he moved out of Muhammad's palace to another residence in the city, and on January 2, 866, he led the prayer for the Feast of Sacrifice. Muhammad, for his part, strove to convince the people that he was still acting in al Musta'in's best interests, while at the same time continuing to negotiate with Abu Ahmad regarding the terms of surrender. On January 7, Muhammad and Abu Ahmad met in person under a canopy outside the Shammasiyah gate, and the two men agreed that the state revenues would be split among the parties, with two thirds going to the Turks and one third going to Muhammad and the Baghdadi army, and al Musta'in should be held liable for part of the soldiers' pay. On the following day, Muhammad went to al Musta'in and attempted to convince him to abdicate. At first al Musta'in adamantly refused, but when the Turkish officers Wasif and Bugha stated that they had sided with Muhammad, he agreed to step down. As part of the terms of al Musta'in's abdication, he was to be given an estate in the Hijaz, and allowed to travel between the cities of Mecca and Medina. On January 12, Muhammad brought a group of judges and jurists to witness that al Musta'in had entrusted his affairs to him. Delegates carrying the terms of abdication were sent to Samarra, where al Mu'tazz personally signed the document and agreed to the conditions. The delegates returned to Baghdad with the signed document on January 24, accompanied by a group of emissaries sent to secure al Musta'in's allegiance to al Mu'tazz. On Friday, January 25, al Mu'tazz was acknowledged as caliph in the mosques throughout Baghdad.

By the beginning of 866, with plots and treachery all around, al Musta'in was persuaded by alternating threats and promises to abdicate in favor of al Mu'tazz. He was to live at Medina with a sufficient income. The conditions signed, the Governor of Baghdad received the ministers and courtiers of al Musta'in, and, having assured them he had done what he had for the best and to stop further bloodshed, sent them to Samarra to pay homage to the new Caliph. Al Mu'tazz ratified the terms and took possession of Baghdad in the early days of 252 AH (866 CE). He also sent to al Musta'in his mother and family from Samarra, but not until they had been stripped of everything they possessed. Instead of finding a refuge at Medina, al Musta'in found himself kept in Baghdad. There he was put to death on 17 October 866 by the order of al Mu'tazz. Carrying al Musta'in's head to the Caliph, "Here," cried the executioner, "behold thy cousin's head!" "Lay it aside," answered al Mu'tazz who was playing chess,—"till I have finished the game." And then, having satisfied himself that it was really al Musta'in's head, he commanded 500 pieces to be given to the assassin as his reward.
