DABUYIDS, the dynasty of espahbads ruling Ṭabarestān until its conquest by the Muslims in 144/761. It is named after its founder Dābūyā (Dābōē, Dādbūya; see Justi, Namenbuch, p. 75), who appears to have reigned at the time of the rise of Islam. The main source for the history of the dynasty is Ebn Esfandīār, whose account of the origins and early years is partly legendary and must be interpreted with caution. Ẓahīr-al-Dīn Marʿašī’s account is of little value. Although it differs on some points from that of Ebn Esfandīār, it does not seem to be based on any independent sources. According to Ebn Esfandīār, the dynasty claimed descent from the Sasanian Jāmāsb, brother of the great king Kavāḏ and ruler of Armenia. His grandson Fīrūz was said to have conquered Gīlān and to have secretly had a son called Gīlānšāh by a native princess. Gīlānšāh’s son Gīl, known as Gāvbāra, extended his rule from Gīlān over Deylamān and later Ṭabarestān and was said to have been granted by Yazdegerd III (632-51) the title Gīl-Gīlān Faršvādgaršāh, by which the later Dabuyid espahbads of Ṭabarestān were known. Faršvādgar (Pātašvārgar) was the old name of the mountains of Ṭabarestān. Gāvbāra’s son Dābūya continued to reside in Gīlān, but Dābūya’s son Farroḵān (Farḵān) moved to Ṭabarestān and fortified the country against Turkish invasions from the east and Deylamite raids from the west. He is reported to have founded the towns of Sārīa (Sārī) and Eṣfahbodān. The latter, apparently located between Sārīa and Āmol, 2 miles from the coast of the Caspian Sea (Ebn al-Faqīh, pp. 303, 310), was the private residence of the espahbads, while Āmol remained the capital of the province. Farroḵān briefly expanded his rule to Khorasan as far as Nīšāpūr and seems to have been granted the title “espahbad of Khorasan” by Yazdegerd in the confused state of affairs during the Arab conquest of Persia. In 31/651-52 he offered the defeated Yazdegerd his country, but the latter refused and fled farther east, where he died (Ṭabarī, I, p. 2875). Although Farroḵān and his successors retained nominal sovereignty over Gīlān and Deylamān, those provinces were virtually independent under local chiefs and kings. The mountains of Ṭabarestān were effectively ruled by two dynasties, the Bāvand (see āl-e bāvand) and the Qārenvand, who nominally recognized Dabuyid overlordship. Actual Dabuyid control was confined to Rūyān and the lowlands of Ṭabarestān as far as Tamīša (Ṭamīs). Gorgān was ruled by a marzbān.
In the account of Ebn Esfandīār the espahbad Farroḵān, called Du’l-Manāqeb Farroḵān-e Bozorg, is said to have ruled from the time of the early Arab invasion of Persia until after the invasion of Ṭabarestān by Yazīd b. Mohallab in 98/716-17. This is obviously impossible. Moreover, Ebn Esfandīār also reported that his rule had lasted seventeen years. That a Farroḵān ruled Ṭabarestān at the time of the initial Arab invasions seems to be confirmed by a letter of safety granted to him, according to Sayf b. ʿOmar, by Sowayd b. ʿAmr b. Moqarren (Ṭabarī, I, pp. 2659-60). The letter gives the impression of being authentic, although its date, the year 18 (639), seems too early and should probably be the year 22 (643). Josef Markwart’s suggestion that Sayf’s account in reality refers to Yazīd b. Mohallab’s attack (Ērānšahr, p. 132) is hardly tenable. In the letter Farroḵān is addressed as “espahbad of Khorasan over (ʿalā) Ṭabarestān” and as “Jīl-Jīlān.” As it is certain from numismatic evidence that an Espahbad Farroḵān was ruling Ṭabarestān until at least 110/728, it must be assumed that the reigns of two or more espahbads have been conflated in Ebn Esfandīār’s account. Modern scholars have mostly tried to resolve the problem by placing the reigns of Gāvbāra and Dābūya within Islamic times (see, e.g., Spuler). This is, however, in clear conflict with Ebn Esfandīār’s account, in which they are described as having reigned in the Sasanian age. Other Islamic sources are of no benefit in this respect, for they usually do not mention the names of the espahbads, even when they refer to them specifically.
Sowayd b. Moqarren did not invade Ṭabarestān and merely asked for a payment of tribute. The first Muslim raid in Ṭabarestān was led by Saʿīd b. ʿĀṣ, governor of Kūfa, in 30/650-51. A number of prominent Companions of the Prophet Moḥammad, including Ḥasan and Ḥosayn, ʿAbd-Allāh b. ʿAbbās, and ʿAbd-Allāh b. Zobayr, are said to have participated. The army reached Tamīša and Nāmīa but apparently did not meet the espahbad. The caliph Moʿāwīa (4160/661-80), or his governor of Kūfa Żaḥḥāk b. Qays Fehrī, sent an army under Maṣqala b. Hobayra, probably in 54/674 (Ḵalīfa, p. 123). Maṣqala penetrated as far as Rūyān, where he was attacked by the men of the espahbad from the mountains. He and his army were annihilated. ʿObayd-Allāh b. Yazīd, as governor of Kūfa (60-64/679-84), appointed Moḥammad b. Ašʿaṯ Kendī governor of Ṭabarestān. Ebn Ašʿaṯ at first concluded a truce, but when there were delays in the payment of tribute he invaded Ṭabarestān. He was defeated, and his son Abū Bakr was killed. Ḥajjāj, as viceroy of Iraq, made various efforts to subdue Ṭabarestān. In 76/695 he ordered Sofyān b. Abi’l-ʿĀlīa with a troop of horsemen to invade Ṭabarestān but then directed him against the rebel Kharijite leader Šabīb Šaybānī. Then he sent a Kufan army under Esḥāq b. Moḥammad b. Ašʿaṯ. In 77/696 or 79/698, when the Kharijite leader Qaṭarī b. Fojāʾa and his men sought refuge in Ṭabarestān, Esḥāq, joined by Sofyān b. Abraṣ, attacked and killed him. According to Ebn Esfandīār’s account (p. 161), the espahbad Farroḵān made a pact with Sofyān b. Abraṣ to get rid of Qaṭarī, and it was the espahbad who killed him. Sofyān b. Abraṣ remained in Ṭabarestān until ca. 82/701 (Ṭabarī, II, p. 1021) but was evidently unable to subdue the country. In 83/702 the espahbad yielded to pressure from Ḥajjāj and surrendered the rebel ʿOmar b. Abi’l-Ṣalt, to whom he had earlier granted shelter in Ṭabarestān. In 98/716 Yazīd b. Mohallab, then governor of Iraq and Khorasan, attempted to conquer Ṭabarestān with a massive army. After taking Dehestān and Gorgān he invaded Ṭabarestān and initially defeated the espahbad. The latter, however, enlisted the help of the Deylamites and Gilites and inflicted a defeat on the Muslims in the mountains. Then he wrote the people of Gorgān, inciting them to revolt against the Muslim troops left there by Yazīd. The latter, apparently in a desperate situation, succeeded by a diplomatic ruse in extracting tribute from the espahbad in return for Muslim withdrawal from Ṭabarestān. In the following year Yazīd was dismissed and imprisoned by the caliph ʿOmar II (99-101/717-20).
The espahbad at that time was evidently Farroḵān-e Bozorg, as stated by Ebn Esfandīār. Coins minted in Ṭabarestān with Pahlavi inscriptions and pictorial representations are known from the year 60 Yazdegerdi (93/711). Coins from 60-70 Yazdegerdi (93-103/711-21) bear the name Farroḵ, whereas those from 71-77 (103-10/721-28) bear the name Farroḵān. On this basis J. M. Unvala suggested that there were two different rulers. John Walker was probably right in assuming that these coins belonged to a single ruler, Farroḵān, who thus, in accordance with Ebn Esfandīār’s statement, ruled for seventeen years. There are no coins of the year 78 Yazdegerdi (111/729), presumably because Farroḵān had died in the previous year. A few coins of the year 79 (112/730) bear the name Farroḵān, whereas others name Dātborzmehr (Dāḏmehr), known from Ebn Esfandīār’s account as the successor of Farroḵān. Those in the name of Farroḵān are most likely posthumous issues. A stray coin of Omayyad type, inscribed with the mint of Ṭabarestān and the year 102 (920-21; Walker, p. 130), seems to reflect an Omayyad attempt to claim sovereignty over the province.
According to Ebn Esfandīār (1, p. 170), Farroḵān’s eldest son, Dāḏmehr, reigned for twelve years. Coins in his name are known from 79 (112/730) to 88 (122/740) Yazdegerdi, with a gap from 80 (113/731) to 85 (119/737). At the time of his death (89 Y./123/741), his son Ḵᵛoršīd was only six years old. Dāḏmehr appointed his own brother Farroḵān-e Kūček, also known as Korbālī (Aṣamm “the deaf”), as temporary successor until Ḵᵛoršīd was of age. The coins of Ṭabarestān do not reflect the reign of Farroḵān-e Kūček but name Ḵᵛoršīd as the ruler from the year 89 Yazdegerdi (123/741). Erroneous readings of the date on some coins with the name of Ḵᵛoršīd have misled earlier scholars to assume that Farroḵān-e Bozorg’s reign was preceded by that of another Ḵᵛoršīd, whom they called Ḵᵛoršīd I and distinguished from the later Ḵᵛoršīd, son of Dāḏmehr. This assumption is no longer tenable. It was evidently during Farroḵān-e Kūček’s reign that Marwān II (127-32/744-50), the last Omayyad caliph, threatened Ṭabarestān and Gīlān (Ḵalīfa, p. 352). Probably shortly afterward Abū Moslem Ḵorāsānī, the ʿAbbasid revolutionary leader, obtained the nominal allegiance of the espahbad.
When Ḵᵛoršīd reached the age of fourteen years his uncle proposed to turn power over to him. Farroḵān-e Kūček’s sons conspired to kill Ḵᵛoršīd, however. The conspiracy was foiled, according to the legendary account of Ebn Esfandīār, by the slave girl Varmja Haravīya, who was in love with Ḵᵛoršīd and whom he later married. Ḵᵛoršīd defeated and imprisoned the sons of Farroḵān-e Kūček. He relied for support on three sons of Jošnas, son of Sārūya, son of Farroḵān-e Bozorg (Aʿẓamī, p. 176). Ebn Esfandīār’s statement (I, p. 171) that Jošnas was a maternal cousin of Ḵᵛoršīd is plainly mistaken. The two were paternal cousins. In Maṛʿašī’s parallel account (p. 47) it is rather the army commander Šahrḵᵛāstān b. Yazdāngerd who is described as Ḵᵛoršīd’s maternal cousin, appointing Vandarand marzbān of Āmol and Fahrān (Bahrām) marzbān of the highlands while keeping Farroḵān in his personal presence.
Having sided with Abū Moslem against the caliph al-Manṣūr (136-58/754-75), Ḵᵛoršīd supported the Zoroastrian Sonbāḏ, who rose in 137/754-55 to avenge the murder of Abū Moslem, and offered him refuge after his defeat by the caliph’s army. Sonbāḏ was killed, however, by Ḵᵛoršīd’s cousin Ṭūs, son of Sārūya (Ṭabarī, III, p. 120, gives a different name), to whom he failed to show respect. Al-Manṣūr then attempted to oust Ḵᵛoršīd by naming Vandād-Hormozd b. Farroḵān (Farroḵān-e Kūček?) espahbad and crowning him (Ṭabarī, III, p. 120). The maneuver failed, however. According to Ebn Esfandīār (I, p. 175), al-Manṣūr later sent a crown to Ḵᵛoršīd in order to lure him to accept the caliph’s overlordship. In return the espahbad sent him such splendid presents that the caliph’s greed was aroused. In 141/758-59 al-Manṣūr gave orders to invade Ṭabarestān. Within two years the province had been conquered. Ḵᵛoršīd fled to a castle in Deylamān. In 144/761, after his wives and children had been captured by the Muslims, he poisoned himself. Coins in his name continued to be minted until 149/766. Nothing is known about the fate of his sons Hormozd; the crown prince, Dāḏmehr; and Vandād-Hormozd. One of Ḵᵛoršīd’s daughters was given by al-Manṣūr to his brother ʿAbbās b. Moḥammad b. ʿAlī, and she bore him his son Ebrāhīm (Ebn Esfandīār, I, p. 177; Ṭabarī, III, p. 137). Another daughter was taken by al-Manṣūr for himself. Boḵtarīya, daughter of Farroḵān-e Kūček, became the mother of the ʿAbbasid Manṣūr b. al-Mahdī (Ṭabarī, III, p. 140). According to Ebn Esfandīār (I, p. 173), Yākand was a wife of her cousin Ḵᵛoršīd, while other sources imply that she was the wife of the maṣmoḡān of Donbāvand (Ṭabarī, III, p. 136; Yāqūt, Boldān I, p. 244). Reports that Šakla, the mother of ʿEbrat-afzā b. al-Mahdī, was a daughter of Ḵᵛoršīd (Ebn al-Nadīm, ed. Flügel, p. 129) seem to be erroneous (see Ṭabarī, III, p. 140).
