Ḥaydar ibn Kāwūs (, ), better known by his hereditary title of al-Afshīn (, ), was a senior general of Sogdian descent at the court of the Abbasid caliphs and a vassal prince of Oshrusana. He played a leading role in the campaigns of Caliph al-Mu'tasim, and was responsible for the suppression of the rebellion of Babak Khorramdin and for his battlefield victory over the Byzantine emperor Theophilos during the Amorium campaign. Eventually he was suspected of disloyalty and was arrested, tried and then executed in June 841.C. Edmund Bosworth (2005), "OSRUŠANA" in Encyclopædia Iranica.

Name and family background

Afshin is a hereditary title of Oshrusana princes before the Muslim conquest of Persia. The term is a modern Persian form of the Middle Persian Pishin and Avestan Pisinah, a proper name of uncertain etymology. Minorsky suggests that the title Afshin was of Sogdian origin.V. Minorsky, Studies in Caucasian history, Cambridge University Press, 1957, (footnote on page 111).

At the time of the first Arab invasion of Transoxiana (including Oshrusana) under Qutayba ibn Muslim (94-5 AH/712-14 CE), Ushrusana was inhabited by Iranians, who were ruled by their own princes who bore the traditional title of Afshin.Kramers, J.H. "Usrūshana." Encyclopaedia of Islam. Edited by: P. Bearman, Th. Bianquis, C.E. Bosworth, E. van Donzel and W.P. Heinrichs. Brill, 2007

Afshin is generally considered an Iranian,Lewis, Bernard. "The Political Language of Islam", Published by University of Chicago Press, 1991. excerpt from pg 482: "Babak's Iranianizing Rebellion in Azerbaijan gave occasion for sentiments at the capital to harden against men who were sympathetic to the more explicitly Iranian tradition. Victor (837) over Babak was al-Afshin, who was the hereditary Persian ruler of a district beyond the Oxus, but also a masterful general for the caliph."Clifford Edmund Bosworth (Translator with Commentary), The History of al-Tabari Vol. 33 "Storm and Stress along the Northern Frontiers of the 'Abbasid Caliphate: The Caliphate of al-Mu'tasim A.D. 833-842/A.H. 218-227", SUNY Press, 1991.

Turks in Early Muslim Service — JTS, 1978, 2, 85—96. excerpt: "Although two classical sources claim him a Turk, he came from Farghana, an Iranian cultural region and was not usually considered Turkish" and although two classical sources (and some modern authors) have called him a Turk.Sourdel, D. "The Abbasid Caliphate." Pages 104-39 in P.M. Holt, Ann K.S. Lambton, and Bernard Lewis (eds.), The Cambridge History of Islam, I. Cambridge: Cambridge University Press, 1970. Quote from Pg 125: "and finally of Mazyar, a local chieftain of Tabaristan, against whom the caliph sent the Turkish general Afshin, the conqueror of Babak" He came from an Iranian cultural region and was not usually considered Turkic. The confusion comes from the fact that the term "Turk" was used loosely by Arab writers of the time to denote the new troops of the caliph despite the inclusion among them of some elements of Iranian origin, including Ferghana and Oshrusana.M.A. Shaban, "Islamic History", Cambridge University Press, v.2 1978. Page 63: "These new troops were the so-called "Turks". It must be said without hesitation that this is the most misleading misnomer which has led some scholars to harp ad nauseam on utterly unfounded interpretation of the following era, during which they unreasonably ascribe all events to Turkish domination. In fact the great majority of these troops were not Turks. It has been frequently pointed out that Arabic sources use the term Turk in a very loose manner. The Hephthalites are referred to as Turks, so are the peoples of Gurgan, Khwarizm and Sistan. Indeed, with the exception of the Soghdians, Arabic sources refer to all peoples not subjects of the Sassanian empire as Turks. In Samarra separate quarters were provided for new recruits from every locality. The group from Farghana were called after their district, and the name continued in usage because it was easy to pronounce. But such groups as the Ishtakhanjiyya, the Isbijabbiya and groups from similar localities who were in small numbers at first, were lumped together under the general term Turks, because of the obvious difficulties the Arabs had in pronouncing such foreign names. The Khazars who also came from small localities which could not even be identified, as they were mostly nomads, were perhaps the only group that deserved to be called Turks on the ground of racial affinity. However, other groups from Transcaucasia were classed together with the Khazars under the general description."ʻUthmān Sayyid Aḥmad Ismāʻīl Bīlī, "Prelude to the Generals", Published by Garnet & Ithaca Press, 2001. pg 47: "The name Turk was given to all these troops, despite the inclusion amongst them of some elements of Iranian origin, Ferghana, Ushrusana, and Shash – places were in fact the centers were the slave material was collected together....Judging from the specific names of their origin, Soghd, Farghana, Urshusuna, Shahs, the majority of them might have been of Iranian origin"

His background has been stated to be Sogdian (an Eastern Iranian people).

Early years According to Yaqubi, during the reign of the third Abbasid caliph Al-Mahdi (775–85), Afshin of Oshrusana was mentioned among several Iranian and Turkic rulers of Transoxania and the Central Asian steppes who submitted nominally to him. But it was not until Harun al-Rashid's reign in 794-95 that al-Fadl ibn Yahya al-Barmaki led an expedition into Transoxania and received the submission of Afshin Kharākana, the ruling Akin.whose name, by inference from Tabari, III, p. 1066, was something like Kharākana; according to Gardīzī led. Habibi, p. 130 Further expeditions were sent to Oshrusana by Al-Ma'mun when he was governor in Merv and later after he had become caliph. Kawus ibn Kharakhuruh, the son of the Afshin Karākana, withdrew his allegiance from the Arabs. However, shortly after Ma'mun arrived in Baghdad from the east (817-18 or 819–20), a power struggle and dissension broke out among the reigning family of Oshrusana.

According to most of the sources, al-Ma'mun's heir, Al-Mu'tasim seconded high-ranking officers to serve under him and ordered exceptionally large salaries, expense allowances, and rations for him. In 831–833, Afshin suppressed uprisings throughout Egypt. On 2 June 832 Afshin succeeded in taking Bima in Egypt. The town surrendered to Afshin following his advice that al-Ma'mun promised safe conduct.

Afshin and Babak

In 835, Caliph al-Mu'tasim appointed Afshin as governor of Adharbayjan to fight against Babak Khorramdin, leader of neo-Mazdakite Persian movement of the Khurramites.

After a fierce resistance by Babak's army, Afshin eventually defeated it and captured Babak's castle of Bazz in August 837. Ya'qubi (Tarikh II, 579) records Afshin freeing 7,600 Arab prisoners from this fortress and destroying the castle. The Khurramite leader went into hiding under the protection of a local Christian prince Sahl ibn-Sunbat who later turned him in to Afshin. In return for Afshin's achievements, the caliph rewarded him with the governorship of Sind in addition to that of Armenia and Adharbayjan.

Amorium campaign

In 838, al-Mu'tasim decided to launch a major punitive expedition against Byzantium, aiming to capture the two major Byzantine cities of central Asia Minor, Ancyra and Amorium. The latter was probably the largest city in Asia Minor at the time, as well as the birthplace of the reigning Amorian dynasty and consequently of particular symbolic importance; according to the chronicles, al-Mu'tasim's soldiers painted the word "Amorium" on their shields and banners. A vast army was gathered at Tarsus (80,000 men according to Treadgold), which was then divided into two main forces. Afshin was placed in command of the northern force, that would invade the Armeniac theme from the region of Melitene, joining up with the forces of the city's emir, Omar al-Aqta. The southern, main force, under the Caliph himself, would pass through the Cilician Gates into Cappadocia and head to Ancyra. After the city was taken, the Arab armies would join and march to Amorium. Afshin's force included, according to Skylitzes, the entire Arab army of Armenia, and numbered 20,000 (Haldon) to 30,000 men (Treadgold), among whom were some 10,000 Turkish horse-archers.

In mid-June 838, Afshin crossed the Anti-Taurus Mountains and encamped at the fort of Dazimon, between Amaseia and Tokate, a strategically important location which the Byzantines also used as a forward staging area. A few days later, on 19 June, the vanguard of the main Abbasid army also invaded Byzantine territory, followed two days after by the Caliph with the main body. Emperor Theophilos chose to confront Afshin first, since although his army was smaller, it threatened to cut off his supply lines. On 21 July, the imperial army came into view of the Arab force, and encamped on the hill of Anzen south of Dazimon. In the ensuing Battle of Anzen, the Byzantine army attacked at dawn, and initially made good progress, but noon Afshin launched his Turkish horse-archers in a ferocious counter-attack which stymied the Byzantine advance and allowed the Arab forces to regroup. At the same time, Theophilos decided to lead reinforcements to one of his wings, and his sudden absence disquieted his troops, thinking he had been killed. The Byzantine army collapsed, with some units breaking and fleeing disorderly, while others were apparently able to retreat in good order. Theophilos himself barely escaped the battle with his guard, and was surrounded by Afshin's men on a low hill. Afshin sent for catapults to be brought up to batter the Byzantine position, but the Byzantines managed to break through the Arab lines and the Emperor escaped.

The caliph's vanguard under Ashinas reached Ancyra, which had been abandoned by its inhabitants, on 26 July. Afshin arrived there a few days later, and united with the main Abbasid army, which now turned south towards Amorium. Afshin commanded the rear guard, while Ashinas was once again in front, and the caliph in the middle. Looting the countryside as they advanced, they arrived before Amorium seven days after their departure from Ancyra, and began their siege of the city on 1 August.
