Battle of Fakhkh
The Battle of Fakhkh was fought on 11 June 786 between the forces of the Abbasid Caliphate and the supporters of a pro-Alid rebellion in Mecca under al-Husayn ibn Ali, a descendant of Hasan ibn Ali, also known as in later histories as the "Man of Fakhkh".
Husayn and his supporters planned an uprising at Medina during the annual pilgrimage of 786, but their hand was forced was by a confrontation with the local governor, al-Umari. The conspirators rose in revolt on the morning of 16 May, and seized the Mosque of the Prophet, where his supporters swore allegiance to Husayn. The revolt failed to gather support among the populace, and the reaction of the Abbasid garrison prevented the rebels from establishing control over the city, and eventually confined them to the Mosque itself. After eleven days, the Alids and their supporters, some 300 strong, abandoned Medina and headed to Mecca.
Informed of these events, the Abbasid caliph al-Hadi appointed his uncle Muhammad ibn Sulayman ibn Ali to deal with the rebels, with an army composed chiefly of the armed retinues of the various Abbasid princes who on that year had gone to the pilgrimage. In the ensuing battle, at the wadi of Fakhkh near Mecca, Husayn and over a hundred of his followers were killed, many others were captured, and some escaped by passing themselves off as pilgrims, including the future founder of the Idrisid dynasty in what is now Morocco. The uprisingled had a strong social character, with Husayn drawing inspiration from Zayd ibn Ali's 740 revolt, and itself impacted later Zaydi Shi'a practices.
Background
The relationship between the Abbasids and the Alids was troubled and underwent many changes. The Alids, claiming descent from Muhammad via Ali ibn Abi Talib, had been the focal point of several failed revolts directed against the Umayyads–whose regime was widely regarded as oppressive and more concerned with the worldly aspects of the caliphate than the teachings of Islam–inspired by the belief that only a "chosen one from the Family of Muhammad" would have the divine guidance necessary to create a truly Islamic government that would bring justice to the Muslim community. However, it was the Abbasid family, who like the Alids formed part of the Banu Hashim clan and hence were members of the wider "Family of the Prophet", who successfully seized the caliphate in 750. Subsequently, the Abbasids tried to secure Alid support or at least acquiescence through salaries and honours at court, but some, chiefly the Zaydi and Hasanid branches of the Alids, continued to reject them as usurpers, with some Alids going into hiding and once again trying to rouse the discontented against the new regime.The second Abbasid caliph, al-Mansur, imprisoned several Alids, and had to face a major revolt in Medina and Basra, headed by Muhammad al-Nafs al-Zakiyya, in 762–763. Thus al-Husayn, a close relative of Muhammad al-Nafs al-Zakiyya—his father Ali was Muhammad's first cousin, and his mother Zaynab was Muhammad's aunt—grew up "in an atmosphere of extreme piety and of secret hatred for the Abbasids". Nevertheless, Husayn had friendly relations with the third Abbasid caliph, al-Mahdi, who gave him money and released an Alid prisoner at Husayn's intercession.
Preparation and outbreak of the revolt at Medina
Shortly after al-Mahdi died in July 785, Husayn and his followers rose in revolt at Medina, hoping to take advantage of the as yet unstable position of al-Mahdi's successor, al-Hadi. Al-Tabari records several traditions that suggest that the immediate cause of the revolt was a quarrel between Husayn and the Abbasid governor of Medina, Umar ibn Abd al-Aziz ibn Abdallah, known as al-Umari. Al-Umari tried to regulate the Alids' movements in the city, and that he had three men, including Abu'l-Zift, a son of Muhammad al-Nafs al-Zakiyya, flogged and publicly humiliated for drinking wine; this caused outrage among the Alids. The situation grew worse when it was discovered that Abu'l-Zift, for whom Husayn and Yahya ibn Abdallah had vouched, had fled the city. In the ensuing confrontation with al-Umari, Yahya and the governor exchanged insults and threats, making the situation untenable for Husayn and his followers. While this may have been the immediate spark for the uprising, from the subsequent passages it is evident that an uprising had been planned for some time, including the recruitment of Kufans who were secretly lying in wait in the city, and the hope of assistance by sympathizers who performed the pilgrimage. The motivation for the revolt is unclear; later Shi'a writers claim that this was due to the hostility of the new caliph, al-Hadi, but there are indications that in his final years al-Mahdi himself had turned from a conciliatory policy to hostility towards the Alids, causing great discontent among the Shi'a.Having quarreled with the governor, the conspirators decided to move on the next morning. Yahya ibn Abdallah went to arrest al-Umari at his residence, but the latter had already gone into hiding. About 26 Alids and some of their supporters gathered at the Mosque of the Prophet, where Husayn took the pulpit dressed in white and wearing a white turban. The rebels reportedly forced the muezzin to pronounce the call to the morning prayer in the Shi'a wording, which was what warned al-Umari that something was afoot. Most people turned away when they saw Husayn in the pulpit, but his followers started arriving and swearing allegiance to him as caliph and imam and as al-Murtaḍā min Āl Muḥammad, "the One pleasing to God from the house of Muhammad". The appellation al-Murtaḍā was evidently adopted as Husayn's honorific title in the fashion of the caliphs. Whether out of the rivalry between the Hasanid and Husaynid branches, or because they thought that the uprising was doomed to failure, two of the Alids refused their support: one of them Musa ibn Ja'far al-Kadhim, who is considered as the seventh imam by the Twelver Shi'a, who reportedly warned Husayn that his actions would only result in his death.
The assembled rebels were confronted by about 200 Abbasid troops from the local garrison, with al-Umari and a certain Khalid al-Barbari at their head. Khalid charged to kill Husayn, but was cut down by Idris ibn Abdallah and Yahya ibn Abdallah, brothers of Muhammad al-Nafs al-Zakiyya; taking heart, the rebels attacked the Abbasid troops, who fled. With the Abbasid partisans repelled, Husayn addressed his followers, concluding his speech with a declaration and oath:
The revolt failed to find many adherents; according to al-Tabari, "the people of Medina locked their doors". On the next morning, the fighting between the partisans of the Alids and the Abbasids spread throughout the city, with the Abbasids driving the Alids back. Fresh Abbasid troops under Mubarak al-Turki arrived on the next day, heartening the Abbasid partisans. After another day of fierce fighting, interrupted only during the hot noon hours, the Alids were confined to the area of mosque, while the Abbasids used the nearby governor's residence as their base. The confrontation lasted for eleven days, during which the Alids, with their failure to secure the city evident, gathered supplies for travel. With about 300 followers, Husayn left the city on 28 May 786. In their wake, they left the mosque in such a state of filth, defiled with bones of the animals the beleaguered Alids had been eating, and its curtains cut up to make kaftans, leading to general indignation among the Medinese.
Confrontation at Fakhkh
With his 300 men, Husayn made for Mecca. On the way, he was joined by sympathizers from that city. In the meantime, Caliph al-Hadi assembled an armed response to Husayn's revolt. Several Abbasid princes were at that time returning from their pilgrimage to Mecca, and one of them, Muhammad ibn Sulayman ibn Ali, had taken a long a strong escort to protect his caravan from Bedouin attacks. Al-Hadi appointed Muhammad to deal with the rebels; he turned back to Mecca, where he was joined by all the armed retinues of the Abbasid elites who had been in the city: the sources refer to 130 men mounted on horses and some mules, 200 on donkeys, and unspecified numbers of infantry. After a parade through the city that was probably designed to intimidate any pro-Alid sympathizers, the Abbasid army encamped at Dhu Tuwa at the edge of the city.As the Alids drew near, the two armies confronted one another on 11 June, at the wadi of Fakhkh, some northwest of Mecca. The Abbasid force was led by the princes al-Abbas ibn Muhammad and Musa ibn Isa on the left, Muhammad ibn Sulayman on the right, and the Khurasani commander Mu'adh ibn Muslim in the centre. The battle began at dawn, and the Alid forces focused on the Abbasids' left wing; when Muhammad ibn Sulayman was victorious on his wing, he led the Abbasid right and centre against the bulk of the Alid army, which had been "massed together as if they were a compact ball of spun thread", in the words of al-Tabari, resulting in a rout of the Alids. During the battle, the Abbasids offered clemency, but Husayn refused it, fighting on until he was killed. His severed head was taken to al-Hadi, who sent it on to Khurasan as a warning to the local Shi'a.
Over a hundred of his followers fell, and were left unburied at the battlefield for three days; but others availed themselves of the amān to surrender. Abu'l-Zift was one of them, surrendering to his uncle, Muhammad ibn Sulayman; but he was killed by Ubayd Allah ibn al-Abbas at the urging of his father, al-Abbas ibn Muhammad, and Musa ibn Isa, leading to a fierce quarrel between the Abbasid princes. Of the Alids taken prisoner, a brother and a son of Muhammad al-Nafs al-Zakiyya were executed at Mecca, while al-Hadi executed at least three other Alid prisoners at Baghdad. Many Alids managed to escape the battle by mingling with the pilgrims. Among them were Idris and Yahya, the brothers of Muhammad al-Nafs al-Zakiyya. Idris eventually moved to the Maghreb, and in 789 established the Idrisid dynasty in the area of modern Morocco, while his brother Yahya in 792 raised a revolt in Daylam. At the news of the Alids' defeat, al-Umari burned the houses of the Alids and their supporters and confiscated their properties.
Impact
Shi'a sources proclaim that Husayn's uprising had a "Zaydi" character, i.e., a social dimension which distinguishes it from the mostly "legitimist" revolt of Muhammad al-Nafs al-Zakiyya. The formula of the oath of allegiance sworn to Husayn was similar to that of Zayd ibn Ali in 740, including promises to defend the oppressed and redress injustices. The historian Laura Veccia Vaglieri points out that in Husayn's formula, "the duty of the subjects to obey him depended on his keeping the promises which he had made", something emulated a century later by al-Hadi ila'l-Haqq Yahya, when he founded a Zaydi state in Yemen. During his brief residence in Medina, he also promised liberty to the slaves who joined him, but faced with protests by their masters that this was an unlawful act, he had to return some of them.The wadi of Fakhkh was thereafter known as al-Shuhadāʾ, and assumed a prominent position in Shi'a martyrology, since in the number of fallen Alids, it was second only to the Battle of Karbala. The revolt's failure exemplified the weakness of the Alids' position, and also the relative success of al-Mahdi's policies in reducing the danger they posed to the regime. In its aftermath, many Alids dispersed from the Hejaz to the far reaches of the Islamic world, with far-reaching repercussions, as they brought Alid loyalties to these regions.
