Kara-Khanid Khanate

Origin

The Kara-Khanid Khanate originated from a confederation formed some time in the 9th century by Karluks, Yagmas, Chigils, Tuhsi, and other peoples living in Zhetysu, Western Tian Shan (modern Kyrgyzstan), and Western Xinjiang around Kashgar.^[12] 10th-century Arab historian Al-Masudi listed two "Khagan of Khagans" of the Karluk horde:^[25] Sanah, a possible rendition of Ashina (compare Śaya (also by al-Masudi), Aś(i)nas (al-Tabari), Ānsa (Hudud al-'Alam), and Śaba (Ibn Khordadbeh)^[26]), and Afrasiab,^[27] whom 11th-century Karakhanid scholar Mahmud al-Kashgari identified with Turkic king Alp Er Tunga, the legendary progenitor of the Karakhanid ruling dynasty.^[28] Furthermore, Kara-khanid heads of state claimed the title khagan, which indicates that they may have been descended from the Ashina.^[29] Even so, the tribal origin of Bilge Kul Qadir Khan, the first Kara-Khan, is still unknown: if Bilge Kul Qadir descended from the Karluk Yabghus,^[30] then he indeed belonged to the Ashina dynasty as they did; if Bilge Kul Qadir descended from the Yagma (as suggested by Vasily Bartold),^[31] then he did not, considering that the Hudud al-'Alam stated that "Their [Yagmas'] king is from the family of the Toġuzġuz kings",^[32] that Ashina tribe was not listed among the Toquz Oghuz (Ch. 九姓 Jĭu Xìng "Nine Surnames") in Chinese-language sources^[33][34] and that early Uyghur khagans belonged to the Yaglakar clan of Toquz Oghuz^[35] and later Uyghur khagans belonged to the Ädiz clan.^[36] Alternatively, Bilge Kul Qadir might belong to the Eðgiş or Chigils.^[37]

Early history

See also: Timeline of the Karluks

The Karluks were a nomadic people from the western Altai Mountains who moved to Zhetysu (Semirechye). In 742, the Karluks were part of an alliance led by the Basmyl and Uyghurs that rebelled against the Göktürks and led to the demise of the Second Turkic Khaganate (682–744).^[38] In the realignment of power that followed, the Karluks were elevated from a tribe led by an Elteber to one led by a yabghu, which was one of the highest Turkic dignitaries and also implies membership in the Ashina clan in whom the "heaven-mandated" right to rule resided. The Karluks and Uyghurs later allied themselves against the Basmyl, and within two years they toppled the Basmyl khagan. The Uyghur yabghu became khagan and the Karluk leader yabghu. This arrangement lasted less than a year. Hostilities between the Uyghur and Karluk forced the Karluk to migrate westward into the western Turgesh lands.^[39]

By 766 the Karluks had forced the submission of the Turgesh and they established their capital at Suyab on the Chu River. The Karluk confederation by now included the Chigil and Tukshi tribes who may have been Türgesh tribes incorporated into the Karluk union. The Karluks converted to Nestorian Christianity at the end of the 8th century CE, about 15 years after they established themselves in the Semerich'e region.^[9] This was the first time the Church of the East received such major sponsorship by an eastern power.^[41] Remains of a Nestorian church have been found in the Karluk capital of Suyab, as well as hundreds of tomstones with Nestorian Syriac inscriptions in the Semerich'e region.^[42]

By the mid-9th century, the Karluk confederation had gained control of the sacred lands of the Western Türks after the destruction of the Uyghur Khaganate by the Old Kirghiz. Control of sacred lands, together with their affiliation with the Ashina clan, allowed the Khaganate to be passed on to the Karluks along with domination of the steppes after the previous Khagan was killed in a revolt.^[43]

During the 9th century southern Central Asia was under the rule of the Samanids, while the Central Asian steppe was dominated by Turkic nomads such as the Pechenegs, the Oghuz Turks, and the Karluks. The domain of the Karluks reached as far north as the Irtysh and the Kimek confederation, with encampments extending to the Chi and Ili rivers, where the Chigil and Tukshi tribes lived, and east to the Ferghana valley and beyond. The area to the south and east of the Karluks was inhabited by the Yagma.^[44] The Karluk center in the 9th and 10th centuries appears to have been at Balasagun on the Chu River. In the late 9th century the Samanids marched into the steppes and captured Taraz, one of the headquarters of the Karluk khagan, and a large church was transformed into a mosque.

Conversion to Islam (c. 934 CE)

In the mid-10th century the Kara-Khanids converted to Islam and adopted Muslim names and honorifics, but retained Turkic regnal titles such as Khan, Khagan, Ilek (Ilig) and Tegin.^[2][52] Later they adopted the Arab titles sultan and sultān al-salātīn ("Sultan of Sultans"). According to the Ottoman historian known as Munajjim-bashi, a Karakhanid prince named Sultan Satuq Bughra Khan was the first of the khans to convert. After conversion, he obtained a fatwa which permitted him in effect to kill his presumably-still-pagan father, after which he conquered Kashgar (of the old Shule Kingdom).^[53] Later, in 960, according to Muslim historians Ibn Miskawaih and Ibn al-Athir, there was a mass conversion of the Turks (reportedly "200,000 tents of the Turks"), and circumstantial evidence suggests these were the Karakhanids.^[53]

Conquest of Transoxiana

The grandson of Satuk Bughra Khan, Hasan b. Sulayman (or Harun) (title: Bughra Khan) attacked the Samanids in the late 10th century. Between 990 and 992, Hasan took Isfijab, Ferghana, Ilaq, Samarkand, and the Samanid capital Bukhara.^[54] However, Hasan Bughra Khan died in 992 due to an illness,^[54] and the Samanids returned to Bukhara.

Hasan's cousin Ali b. Musa (title: Kara Khan or Arslan Khan) resumed the campaign against the Samanids, and by 999 Ali's son Nasr had taken Chach, Samarkand, and Bukhara.^[2] The Samanid domains were divided between the Ghaznavids, who gained Khorasan and Afghanistan, and the Karakhanids, who received Transoxiana. The Oxus River thus became the boundary between the two rival empires.

The Karakhanid state was divided into appanages (Ülüş system), as was common of Turkic and Mongol nomads. The Karakhanid appanages were associated with four principal urban centers, Balasagun (then the capital of the Karakhanid state) in Zhetysu, Kashgar in Xinjiang, Uzgen in Fergana, and Samarkand in Transoxiana. The dynasty's original domains of Zhetysu and Kasgar and their khans retained an implicit seniority over those who ruled in Transoxiana and Fergana.^[12] The four sons of Ali (Ahmad, Nasr, Mansur, Muhammad) each held their own independent appanage within the Karakhanid state. Nasr, the conqueror of Transoxiana, held the large central area of Transoxiana (Samarkand and Bukhara), Fergana (Uzgen) and other areas, although after his death his appanage was further divided. Ahmad held Zhetysu and Chach and became the head of the dynasty after the death of Ali. The brothers Ahmad and Nasr conducted different policies towards the Ghaznavids in the south – while Ahmad tried to form an alliance with Mahmud of Ghazna, Nasr attempted to expand unsuccessfully into Ghaznavid territory.^[2]

Ahmad was succeeded by Mansur, and after the death of Mansur, the Hasan Bughra Khan branch of the Karakhanids became dominant. Hasan's sons Muhammad Toghan Khan II, and Yusuf Kadir Khan who held Kashgar, became in turn the head of the Karakhanid dynasty. The two families, i.e., the descendants of Ali Arslan Khan and Hasan Bughra Khan, would eventually split the Karakhanid Khanate in two.

In 1017–1018, the Karakhanids repelled an attack by a large mass of nomadic Turkic tribes in what was described in Muslim sources as a great victory.^[56] Around the same time, the Kara-Khanid ruler Ilig Khan reached an agreement with Mahmud of Ghazni, in which they agreed to partition former Samanid territory along the Oxus river.^[55]

Conquest of western Tarim Basin

The Islamic conquest of the Buddhist cities east of Kashgar began when the Karakhanid Sultan Satuq Bughra Khan converted to Islam in 934 and then captured Kashgar. He and his son directed endeavors to proselytize Islam among the Turks and engage in military conquests.^[57] In the mid-10th century, Satuq's son Musa began to put pressure on Khotan, and a long period of war between Kashgar and the Kingdom of Khotan ensued.^[58] Satok Bughra Khan's nephew or grandson Ali Arslan was said to have been killed by Buddhists during the war;^[59] during the reign of Ahmad b. Ali, the Karakhanids also engaged in wars against non-Muslims to the east and northeast.^[60]

Muslim accounts tell the tale of the four imams from Mada'in city (possibly now in Iraq) who travelled to help Yusuf Qadir Khan, the Qarakhanid leader, in his conquest of Khotan, Yarkend, and Kashgar. The "infidels" were said to have been driven towards Khotan, but the four Imams were killed.^[61] In 1006, Yusuf Qadir Khan of Kashgar conquered the Kingdom of Khotan, ending Khotan's existence as an independent state.^[62]

The conquest of the western Tarim Basin which includes Khotan and Kashgar is significant in the eventual Turkification and Islamification of the Tarim Basin, and modern Uyghurs identify with the Karakhanids even though the name Uyghur was taken from the Manichaean Uyghur Khaganate and the Buddhist state of Qocho.^[63][64]

Division of the Kara-Khanid Khanate

Early in the 11th century the unity of the Karakhanid dynasty was fractured by frequent internal warfare that eventually resulted in the formation of two independent Karakhanid states. A son of Hasan Bughra Khan, Ali Tegin, seized control of Bukhara and other towns. He expanded his territory further after the death of Mansur. The son of Nasr, Böritigin, later waged war against the sons of Ali Tegin, and won control of a large part of Transoxiana, making Samarkand the capital. In 1041, another son of Nasr b. Ali, Muhammad 'Ayn ad-Dawlah (reigned 1041–52) took over the administration of the western branch of the family that eventually led to a formal separation of the Khara-Khanid Khanate. Ibrahim Tamghach Khan was considered by Muslim historians as a great ruler, and he brought some stability to the Western Karakhanids by limiting the appanage system that caused much of the internal strife in the Kara-Khanid Khanate.^[2]

The Hasan family remained in control of the Eastern Khanate. The Eastern Khanate had its capital at Balasaghun and later Kashgar. The Fergana-Zhetysu areas became the border between the two states and were frequently contested. When the two states were formed, Fergana fell into realm of the Eastern Khanate, but was later captured by Ibrahim and became part of the Western Khanate.

Seljuk suzerainty

In 1040, the Seljuk Empire defeated the Ghaznavids at the Battle of Dandanaqan and entered Iran. Conflict with the Karakhanids broke out, but the Karakhanids were able to withstand attacks by the Seljuks initially, even briefly taking control of Seljuk towns in Greater Khorasan. The Karakhanids, however, developed serious conflicts with the religious classes (the ulama), and the ulama of Transoxiana then requested the intervention of the Seljuks. In 1089, during the reign of Ibrahim's grandson Ahmad b. Khidr, the Seljuks entered and took control of Samarkand, together with the domains belonging to the Western Khanate. For half a century, the Western Karakhanid Khanate was a vassal of the Seljuks, who largely controlled the appointment of the Khanate's rulers in that time. Ahmad b. Khidr was returned to power by the Seljuks, but in 1095, the ulama accused Ahmad of heresy and managed to secure his execution.^[2]

The Karakhanids of Kashgar also declared their submission following a Seljuk campaign into Talas and Zhetysu, but the Eastern Khanate was a Seljuk vassal for only a short time. At the beginning of the 12th century the Eastern Khanate invaded Transoxiana and briefly occupied the Seljuk town of Termez.^[2]

Qara Khitai invasion

The Qara Khitai (Western Liao dynasty) host which invaded Central Asia was composed of remnants from the defunct Liao dynasty which was annihilated by the Jin dynasty in 1125. The Liao noble Yelü Dashi recruited warriors from various tribes and formed a horde that moved westward to rebuild the Liao dynasty. Yelü occupied Balasagun on the Chu River, then defeated the Western Karakhanids in Khujand in 1137.^[68] In 1141 Qara Khitai became the dominant force in the region after they dealt a devastating blow to the Seljuk Sultan Ahmad Sanjar and the Kara-Khanids at the Battle of Qatwan near Samarkand.^[12] Several military commanders of Karakhanid lineages such as the father of Osman of Khwarazm fled from Karakhanid lands in the wake of the Qara Khitai invasion.

Despite losing to the Qara Khitai, the Karakhanid dynasty remained in power as their vassals. The Qara Khitai themselves stayed at Zhetysu near Balasagun, and allowed some of the Karakhanids to continue to rule as their tax collectors in Samarkand and Kashgar. Under the Qara Khitai the Karakhanids functioned as administrators for sedentary Muslim populations. While the Qara Khitai were Buddhists ruling over a largely Muslim population, they were considered fair-minded rulers whose reign was marked by religious tolerance.^[12] Islamic religious life continued uninterrupted and Islamic authority persevered under the Qara Khitai. Kashgar became a Nestorian metropolitan see and Christian gravestones in the Chu River Valley appeared beginning in this period.^[68] However, Kuchlug, a Naiman who usurped the throne of the Qara Khitai dynasty, instituted anti-Islamic policies on the local populations under his rule.^[73]

Downfall

The decline of the Seljuks following their defeat by the Qara Khitais at the Battle of Qatwan (1141) allowed the Khwarazmian dynasty, then a vassal of the Qara Khitai, to expand into former Seljuk territory, where they became independent rulers circa 1190. In 1207, the citizens of Bukhara revolted against the sadrs (leaders of the religious classes), which the Khwarazmshah 'Ala' ad-Din Muhammad used as a pretext to conquer Bukhara. Muhammad then formed an alliance with the Western Karakhanid ruler Uthman ibn Ibrahim (who later married Muhammad's daughter) against the Qara Khitai. In 1210, the Khwarezm-Shah took Samarkand after the Qara Khitai retreated to deal with the rebellion from the Naiman Kuchlug, who had seized the Qara Khitans' treasury at Uzgen.^[2] The Khwarezm-Shah then defeated the Qara Khitai near Talas. Muhammad and Kuchlug had, apparently, agreed to divide up the Qara Khitan's empire.^[74] In 1212, the population of Samarkand staged a revolt against the Khwarezmians, a revolt which Uthman supported, and massacred them. The Khwarezm-Shah returned, recaptured Samarkand and executed Uthman. He demanded the submission of all leading Karakhanids, and finally extinguished the Western Karakhanid state.

In 1204, a rebellion of the Eastern Kara-Khanid in Kashgar was suppressed by the Kara-Khitai who took the prince Yusuf hostage to Balasagun.^[75] The prince was later released but he was killed in Kashgar by rebels in 1211, effectively ending the Eastern Kara-Khanid.^[75] In 1214, the rebels in Kashgar surrendered to Kuchlug, who had usurped the Kara-Khitai throne.^[75] In 1218, Kuchlug was killed by the Mongol army. Some of the Kara-Khitai's eastern vassals including Eastern Kara-Khanids then joined the Mongol forces to conquer the Khwarezmian Empire.^[76]
