The Hephthalites were the last power of Hunnic descent to rule Central Asia, and the first great conquest of the Göktürk in the west. At their height in the early sixth century they held Sogdia and the country from Afghanistan to the oasis cities of the Tarim, took tribute from north-western India, and had twice decided who sat on the Sasanian throne. Within a few years of the founding of the khaganate they were gone, destroyed by Istemi and Khosrow I acting from opposite sides.

Name and composition

One point the name obscures deserves emphasis: the Hephthalites[1] should not be read as a distinct ethnic group at all, but as a confederation of nomadic and semi-nomadic groups — Altaic, Iranian and probably others — held together by the Heftal dynasty and a core of War-Hun tribes. Their name in the sources is the name of a ruling house that gathered them, not of a nation that produced one. The same reading goes back to Marquart a[1] century earlier — under the name Hephthal only a ruling political entity is to be understood, the mass of the state being Kidarites, Kushans, Chionites and Huns — and from Trever the judgement that the few data on their language show Turkic and Iranian elements and elements that are neither, a mixture indicative of an extremely mixed speech; he closes his own review of the theories with the remark that many opinions compete and no general agreement is possible at the moment.

The prehistory runs through two earlier waves. In the middle of the fourth century a people called Xiyōn in Middle Persian and Chionitae in Latin began to press on the Sasanian frontier; the name is in all likelihood a rendering of the same ethnonym the Chinese wrote as Xiongnu. Around 360 their chieftain Grumbates fought in Shapur II’s Roman war as a Persian ally. A second grouping formed under a chief named Kidāra, whom the Byzantine sources call the Kidarite Huns, and towards the end of the century new bands — probably War-Huns — entered the region and pushed the Kidarites west towards Balkh and northern India, where Indian inscriptions know them as the Śveta Hūṇas, the White Huns, under Toramāṇa and Mihirakula. It was out of this movement, and probably in connection with Rouran pressure, that the Heftal dynasty emerged by the middle of the fifth century.

The founder was Khingila, who united the Chionites and the Uar after they had[2] fled westward before the Wusun, who were themselves being driven by the rising Rouran; on that reading the later closeness of Hephthalites and Rouran is a family matter before it is a political one. Whether the Rouran were in fact their overlords is not settled.

Language and origins

The disagreement is old. The Liang Shu reports that their language could be understood only by speakers of Tuyuhun; other accounts say it differed from that of the Rouran, who are believed to have spoken a form of the same Xianbei stock. Once established, they used Bactrian, the language of the population and the bureaucracy they had conquered — which tells us what they ruled, not what they were.

The Zhou Shu derives them from the Great Yuezhi, puts their king’s seat in a walled city west of Khotan, and remarks that their penal law and customs are about the same as those of the Göktürk; it also records that brothers share one wife, who wears one horn on her hat if her husband has no brothers and adds a horn for each brother he has, that Khotan, Parthia and more than twenty states great and small were subject to them, and that after the Göktürk broke them their people scattered and their tribute ceased.[3] Prokopios calls them a people of Hunnic stock but adds that they had long lived apart from the Huns, in a good land, and are the only Huns with white bodies and faces; he also describes retinues of personal servitors around their aristocrats, the comitatus familiar from the Iranian and Turkic world.

The seventh-century Chinese traveller Wei Jie, who met Hephthalites on a Sui mission to the western countries, gave the honest answer: what comes from distant lands and foreign tongues is corrupted and misunderstood and concerns very old times, so that it is impossible to determine the origin of the Hephthalites. The words are known in the rendering after Enoki.[1] Fifteen centuries later the question is still open, and the difficulty is not only the state of the sources: a confederation does not have one origin.

Rule over Sogdiana

The Hephthalite conquest of Sogdiana falls in 509, not from any written record but from the abrupt replacement of Sogdian by Hephthalite embassies at the Chinese court in that year, and from the walls and a temple at Panjikent, partly destroyed and at once repaired, with a three-storey barracks for a permanent garrison added to the outer wall.[4] The Kidarite dynasty they displaced had probably been waning since the 470s, beaten by the Sasanians and by the Hephthalites themselves, who had driven it from its Bactrian bases from 456. The conquerors were fabulously rich. They had killed Peroz in 484, they had put his successor Kavad on the throne of Iran and back on it more than once, and for decades, at least to the beginning of Khosrow’s reign, the Sasanians paid them a colossal tribute; on one occasion Peroz sent as many silver coins as thirty mules could carry, and those coins are still found by the thousand in the markets of Afghanistan. A great part of the Sasanian money supply went that way to Central Asia, the Sasanian apocalyptic texts count Sogdian troops among the pillagers of Iran, and the Sogdians, who merely changed masters and went on trading in China, spread the silver through an empire that at its height in 520 nominally ran from Merv to Turfan and Gandhara; Sasanian silver became the currency of all Central Asia to Gansu for close on two centuries, and the Sogdian merchants found in it the capital to enlarge their trade. The one Hephthalite of the years after the fall who is named in a western source is Katulph, who at the Persian court advised Khosrow to buy the Göktürk silk and burn it; the Maniakh article carries the scene.[5]

Relations with Sasanian Persia

Their relations with Sasanian Iran are the textbook case of what a nomadic power beside a settled empire could do. They raided the borderlands; they sold their cavalry to claimants for the throne; and they killed a king who came looking for their treasure. Peroz took the crown from his brother Hormizd III with Hephthalite help and died in battle against those same allies in 484; Kavad regained his throne with Hephthalite assistance and may have had to acknowledge their overlordship to do it. At that moment they were, in effect, the arbiters of the Sasanian succession.

Destruction by the Göktürk and Persia

Then came the Göktürk. Istemi, his brother Bumin‘s viceroy for the west, moved against them in alliance with Khosrow I, the Göktürk from the north-east and the Persians from the south-west, and the Hephthalite state was destroyed and its ruler killed. The territory was divided between the victors along the Oxus — the arrangement that would sour into the Göktürk–Persian war within a generation.

The realm fell about 560. The decisive engagement, the battle of Bukhara, belongs to those years, and Istemi concluded the alliance with Khosrow only shortly before the invasion.[2] Two other datings are held. Peter B. Golden puts the destruction in 557.[6] Aydogdy Kurbanov, reviewing the proposals — 557 with Drouin, 558 with Frye, 563 with Saint-Martin, 565 with Grousset — sets the end between 563 and 567, on the ground that Menander’s envoys of 568 could answer the emperor’s question whether they had subjected all the Hephthalites with the one word “all”.[1] The difference of a decade sits at the junction of Chinese, Persian, Arabic and Greek reckonings. The fullest reconstruction of the campaign, assembled from Firdausi, Tabari, Dinawari and the[1] Greeks, runs as follows. The Göktürk reached the Aral Sea and the Hephthalite border in 555; the Sasanian–Göktürk alliance was sealed by the marriage of Khosrow to a daughter of Istemi, in 554 by one reckoning or after the victory by another; the first collision, under Mukan, fell in 555 and the second, under Istemi, in 558. The Hephthalite king Gatfar had a counsellor named Katulf who advised against war and, insulted, went over to Khosrow; the Hephthalites killed a Göktürk embassy passing through Sogd, all but one man, and the war became inevitable. The Göktürk took Chach and crossed the Chirchik; Gatfar gathered troops from Balkh, Shughnan, Termez and the rest of the realm near Bukhara, declined battle on the plain, and fought in the hills at Nesef, where after eight days the Göktürk won. The survivors chose the ruler of Chaghaniyan, Faganish, who submitted to the Sasanians; Khosrow took the country south of the Amu Darya, the Göktürk took Sogd, Chach, Ferghana and eastern Turkistan, by an agreement dated to 566 or 571; and the Amu Darya[1] became the frontier, with northern Tokharistan a Hephthalite buffer paying tribute to the Göktürk. Every element of that account is reconstruction from sources at second hand,[1] and it stands here as his.

The name of the last king is not secure either. Tabari gives him as Wrz, al-Masʿudi as Axsunwāz — which recalls Axsunwār, the title or name borne by the Hephthalite ruler in Peroz’s day.[7]

Aftermath and legacy

The collapse ended the last of the War-Hun confederations and opened the western steppe to the Göktürk; that is its significance for this encyclopaedia. Remnants stayed in Bactria as Göktürk vassals and fought beside them against the Sasanians; part of the Hephthalite nobility later passed under Persian rule instead. Petty dynasts of Hephthalite origin may have continued in the region for generations.

When they ceased to exist as a cultural unit nobody can say, and the reason is the one given above: their population was mixed from the start. Traces have been claimed in the ethnogenesis of the Pashtuns, of the Turkic Karluk and Khalaj in Afghanistan, and of the Äynu of eastern Turkistan; al-Khwārazmī has been read to connect the Khalaj and the Kanjina with them. These are proposals, not findings, and they are recorded here as proposals.
