Tokhara Yabghus

The Tokhara Yabghus or Yabghus of Tokharistan (), were a dynasty of Western Turk-Hephtalite sub-kings, with the title "Yabghus", who ruled from 625 CE in the area of Tokharistan north and south of the Oxus river, with some smaller remnants surviving in the area of Badakshan until 758 CE. Their legacy was extended to the southeast until the 9th century CE, with the Turk Shahis and the Zunbils.
Territorial expansion.
The Turks initially occupied the area of north of the Oxus (Transoxonia, Sogdiana) following their destruction of the Hephthalites in 557–565 CE through an alliance with the Sasanian Empire. The Sasanians, on the other hand, took control of the area south of the Oxus, with Chaganiyan, Sind, Bust, Rukhkhaj, Zabulistan, Tokharistan, Turistan and Balistan being transformed into vassal kingdoms and principalities. After this time, a tense Turco-Persian border existed along the Oxus, which lasted several decades. The area south of the Oxus contained numerous Hephthalites principalities, remnants of the great Hephthalite Empire destroyed by the alliance of the Turks and the Sasanians.
First offensive into Tokharistan (569-570 CE).
In 569-570, the Turks launched an offensive against the Sasanian Empire, and conquered the Hephthalite principalities south of the Oxus belonging to the Sasanian Empire. At that time the Sasanian Empire was embroiled in a war in the west, with the Byzantine Empire. It seems the Turks reached the Kabul–Gandhara area in 570. The principalities of the Hephthalites, formerly vassals of the Sasanian Empire, accepted Turk supremacy and became vassals of the Western Turk qaghan, and the Alchon Huns continued to rule in Kabul and Gandhara, but the Turks apparently did not permanently occupy the territory south of the Oxus. The Hephthalites aspired to independence from the Turks, and in 581 or 582 CE, they revolted in alliance with the Sasanians against the Turk Kaghan Tardu.
Second offensive into Tokharistan (588-589 CE).
In 588-589, the Turks under Bagha Qaghan entered into a direct conflict with the Sasanians, in the First Perso-Turkic War. The Turks invaded the Sasanian territories south of the Oxus, where they attacked and routed the Sasanian soldiers stationed in Balkh, and then proceeded to conquer the city along with Talaqan, Badghis, and Herat. But the Turks were defeated by the Sasanians under Bahram Chobin, who entered the area north of the Oxus and killed the Turkish Khagan.
War against the Sasanians Empire (616–617 CE).
A war war broke out between the Sasanians and the Hephthalites in 606-607 or 616–617 CE, the Second Perso-Turkic War. At that time, the Türk kaghan sent an army to help the Hephthalites, and was able to bring a great defeat upon the Sasanians, advancing his troops as far as Ray and Isfahan, but Sheguy Kaghan recalled his armies without pressing his advantage.
Occupation of Tokharistan under Tong Yabghu Qaghan (625 CE).
The Turks definitely intended to take control of the territories south of the Oxus, but were only ready sometime later, and took the opportunity when the Sasanian Empire again entered into conflict with the Byzantine Empire.
In 625, Tong Yabgu invaded Tokharistan and forced the Hephtalite principalities to submit. He went as far as the Indus river and took control of all the intervening principalities, replacing Hepthalite rulers by Turk ones. The Turks were victorious, partly because the Sasanian Empire was into a difficult war with the Byzantine Empire, the Byzantine–Sasanian War of 602–628.
According to Cefu Yuangui, these principalities were Zabulistan, Kapisa-Gandhara, Khuttal, Chaghaniyan, Shignan, Shuman, Badhgis, Wakhan, Guzgan, Bamiyan, Kobadiyan and Badakhshan. The areas of Khuttal and Kapisa-Gandhara had remained independent kingdoms under the easternmost "Hephthalites" (actually Alchon Hun) under kings such as Narendra, before being taken over as vassals by the Western Turks. The appearance of the "crown with a bull's head" on the coin portraits of the last rulers of Kapisa-Gandhara Narendra II, can be considered as a sign of recognition of Turk sovereignty, since the title "buqa" (bull) had been in use from 599, when Khagan Tardu united the Turk Empire.
Tong Yabghu Qaghan then installed his son Tardush Shad (), as the first yabgu (sub-king) of Tokharistan, controlling all the new Turk realm south of the Oxus, from his capital at Kunduz.
Reign of Tardush Shad (625-630).
Tardush Shad () was installed in Tokharistan, and ruled in Kunduz with title of Tokharistan Yabgu (). He was married two times - both a daughter of Qu Boya (麴伯雅) - ruler of Qocho. When Xuanzang visited Kunduz, he also brought a letter from his brother-in-law and ruler of Qocho Qu Wentai (麴文泰) to Tardu. Yabgu received him despite being in ill condition. It was Tardu to advise him to make a trip westward to Balkh (modern Afghanistan), to see the Buddhist sites and relics. Xuanzang also witnessed a palace scandal when Tardu's firstborn son Ishbara Tegin fallen in love with his new step-mother (also aunt) and poisoned Tardu in 630.
Reign of Ishbara Yabgu (630-650).
Ishbara Yabgu () was the son of Tardu Shad, and took over as Tokharistan Yabgu. He was the first Tokharistan Yabghu to mint coins. In these coins, in Sasanian style, he effigy represents him bearing a crown decorated with the bull's head and two wings. In one of the issues, the legend is: šb’lk’ yyp MLK’ ("Išbara Jeb ˇ [= yabghu] šah", on the obverse) and pnˇcdh. h. wsp’ ("[minted in his] 15th [regnal year at] Khusp", on the reverse). This would date the coin to 645 CE, with a location for the mint at Khusp, Kuhistan. Other known mints are Herat and Shuburgan.
After 650 however, the power of the Yabghus of Tokharistan fragmented, as they came, as least partially, under Tang suzerainty. A Türk yabghu of Tokharistan recorded under the name of "Wu-shih-po of the A-shih-na dynasty" was the first yabghu to be confirmed by the Chinese Emperor.
In 652–653 CE, the Arabs under Abdallah ibn Amir conquered the whole of Tokharistan and captured the city of Balkh, as part of the Muslim conquests of Afghanistan.
The Western Turkic Khaganate itself was destroyed by the Tang Dynasty in 657 CE, and most of his territories became protectorates of the Tang Empire, and organized into regional commanderies. Kunduz became the site of the Yuezhi Commandery (月氏都督府, "Yuèzhī Dūdùfû") under administration of the Anxi Protectorate.
During the rule of the Umayyad caliph Ali (656–661), the Arabs were expulsed from eastern Iran, as far as Nishapur and the Sasanian Peroz III was able to establish some level of control with the help of the yabghu of Tokharistan in Seistan.
Reign of Pantu Nili (c.705 CE).
In 705, P’an-tu-ni-li, the yabghu of Tokharistan, is recorded as having sent a mission to the Chinese court. He ruled from Badakshan, as the area of Balkh and the central areas of his territory were occupied by the Arabs, including Shuburgan, Khusp and Herat.
Suzerainty over the territories north and south of the Hindu-Kush.
According to the chronicles of the Chinese "Cefu Yuangui", a young brother of Pantu Nili named Puluo (僕羅 "púluó" in Chinese sources) again visited the Tang court in 718 and gave an account of the military forces in the Tokharistan region. Puluo described the power of "the Kings of Tokharistan", explaining that "Two hundred and twelve kingdoms, governors and prefects" recognize the authority of the Yabghus, and that it has been so since the time of his grand-father, that is, probably since the time of the establishment of the Yabghus of Tokharistan. The territory of Guzgan was also mentioned among the territories controlled by the Yabghus. Puluo finally reaffirmed the loyalty of Yabghu Pantu Nili towards the Tang Dynasty.
Part of the Chinese entry for this account by Puluo is:
This account also shows that the Yabghu of Tokharistan ruled a vast area circa 718 CE, formed of the territories north and south of the Hindu Kush, including the areas of Kabul and Zabul.
Contacts with the Byzantine Empire.
The East Roman Emperor Leo III the Isaurian who had defeated their common enemy the Arabs in 717 CE, sent an embassy to China through Central Asia in 719 CE which probably met with the Tokhara Yabghus and the Turk Shahis, who in honour of the Byzantine Emperor even named one of their own rulers "Caesar of Rome" (which they rendered phonetically as King "Fromo Kesaro"). The Chinese annals record that "In the first month of the seventh year of the period Kaiyuan [719 CE] their Lord [拂菻王, "the King of Fulin"] sent the Ta-shou-ling [an officer of high rank] of T'u-huo-lo [吐火羅, Tokhara] (...) to offer lions and ling-yang [antelopes], two of each. A few months after, he further sent Ta-te-seng ["priests of great virtue"] to our court with tribute."
Chinese sources.
Turk ("T’u-chüeh") kingdoms were in the territories of Gandhara, Kapisa and Zabulistan around 723-729 CE, according to the testimony the Korean pilgrim Hui Chao. Huei-chao also mentioned that in 726 CE, the Arabs occupied Balkh, and the Turks were forced to flee to Badakshan:
Chinese sources mention a few years later yabghus who sent missions to the Tang court: Ku-tu-lu Tun Ta-tu (Qutluγ Ton Tardu) asked for help against the Arabs in 729 CE, Shih-li-mang-kia-lo (Sri Mangala) asked for help against the Tibetans in 749 CE, and received this help from the Chinese, and in 758 CE Wu-na-to (Udita?) visited in person the Chinese court and participated in the fight against the rebel An Lu-shan.
Kapisa-Gandhara.
In the area of Kapisa-Gandhara, the Turk Shahi (665–850 CE), a probable political extension and vassals of the neighbouring Yabghus of Tokharistan, remained an obstacle to the eastward expansion of the Abbasid Caliphate.
Circa 650 CE, the Arabs attacked Shahi territory from the west, and captured Kabul. But the Turk Shahi were able to mount a counter-offensive and repulsed the Arabs, taking back the areas of Kabul and Zabulistan (around Ghazni), as well as the region of Arachosia as far as Kandahar. The Arabs again failed to capture Kabul and Zabulistan in 697-698 CE, and their general Yazid ibn Ziyad was killed in the action.
From 719 CE, Tegin Shah was the king of the Turk Shahis. He then abdicated in 739 CE in favour of his son Fromo Kesaro, probable phonetic transcription of "Caesar of Rome" in honor of "Caesar", the title of the then East Roman Emperor Leo III the Isaurian who had defeated their common enemy the Arabs in 717 CE, and sent an embassy through Central Asia in 719 CE. Fromo Kesaro appears to have fought vigorously against the Arabs, and his victories may have forged the Tibetan epic legend of King Phrom Ge-sar.
The Turk Shahis eventually weakened against the Arabs in the late 9th century CE. Kandahar, Kabul and Zabul were lost to the Arabs, while in Gandhara the Hindu Shahi took over. The last Shahi ruler of Kabul, Lagaturman, was deposed by a Brahmin minister, possibly named Vakkadeva, in c. 850, signaling the end of the Buddhist Turk Shahi dynasty, and the beginning of the Hindu Shahi dynasty of Kabul.
Local art at the time of the Yabghus of Tokharistan (7-8th century CE).
These was a relatively high level of artistic activity in the areas controlled by the Yabghus of Tokharistan during 7-8th centuries CE, either as a result of the Sasanian cultural heritage, or as a result of the continued development of Buddhist art. The works of art of this period in Afghanistan, with a sophistication and cosmopolitanism comparable to other works of art of the Silk Road such as those of Kizil, are attributable to the sponsorship of the Turks.
Buddhism.
Buddhism in Tokharistan is said to have enjoyed a revival under the Turks. Several monasteries of Tokharistan dated to the 7th-8th centuries display beautiful Buddhist works of art, such as Kalai Kafirnigan, Ajina Tepe, Khisht Tepe or Kafyr Kala, around which Turkic nobility and populations followed Hinayana Buddhism. The Turks were apparently quite tolerant of other religions.
Bamiyan murals and their devotees.
The mural paintings of Bamiyan display male devotees in double-lapel caftans, also attributable to the local sponsorship of the Western Turks.
