(Tokhara Yabghus, Turk Shahis) The Khazars[a] (/ˈxɑːzɑːrz/) were a nomadic Turkic people that, in the late 6th century CE, established a major commercial empire covering the southeastern section of modern European Russia, southern Ukraine, Crimea, and Kazakhstan.

[11] Astride a major artery of commerce between Eastern Europe and Southwestern Asia, Khazaria became one of the foremost trading empires of the early medieval world, commanding the western marches of the Silk Road and playing a key commercial role as a crossroad between China, the Middle East, and Kievan Rus'.

A variegated tribal federation led by these Turks, probably comprising a complex assortment of Iranian,[note 13] proto-Mongolic, Uralic, and Palaeo-Siberian clans, vanquished the Rouran Khaganate of the hegemonic central Asian Avars in 552 and swept westwards, taking in their train other steppe nomads and peoples from Sogdiana.

[47] The ruling family of this confederation may have hailed from the Āshǐnà (阿史那) clan of the Western Turkic Khaganate,[48][49][50] although Constantine Zuckerman regards Ashina and their pivotal role in the formation of the Khazars with scepticism.

[60] Historians have often referred to this period of Khazar domination as the Pax Khazarica since the state became an international trading hub permitting Western Eurasian merchants safe transit across it to pursue their business without interference.

The greater king was recruited from the Khazar house of notables (ahl bait ma'rûfīn) and, in an initiation ritual, was nearly strangled until he declared the number of years he wished to reign, on the expiration of which he would be killed by the nobles.

[71][note 21] The ruling stratum, like that of the later Činggisids within the Golden Horde, was a relatively small group that differed ethnically and linguistically from its subject peoples, meaning the Alano-As and Oğuric Turkic tribes, who were numerically superior within Khazaria.

[77] Many Turkic nations had a similar (political, not racial) division between a "white" ruling warrior caste and a "black" class of commoners; the consensus among mainstream scholars is that Istakhri was confused by the names given to the two groups.

The capital Atil reflected the division: Kharazān on the western bank where the king and his Khazar elite, with a retinue of some 4,000 attendants, dwelt, and Itil proper to the East, inhabited by Jews, Christians, Muslims and slaves and by craftsmen and foreign merchants.

[88] While customs duties were imposed on traders, and tribute and tithes were exacted from 25 to 30 tribes, with a levy of one sable skin, squirrel pelt, sword, dirham per hearth or ploughshare, or hides, wax, honey and livestock, depending on the zone.

In 724, the Arab general al-Jarrah ibn Abdallah al-Hakami inflicted a crushing defeat on the Khazars in a long battle between the rivers Cyrus and Araxes, then moved on to capture Tiflis, bringing Caucasian Iberia under Muslim suzerainty.

[108] The Qağan was forced to accept terms involving his conversion to Islam, and subject himself to the rule of the Caliphate, but the accommodation was short-lived because a combination of internal instability among the Umayyads and Byzantine support undid the agreement within three years, and the Khazars re-asserted their independence.

[109] The suggestion that the Khazars adopted Judaism as early as 740 is based on the idea that, in part, it was, a re-assertion of their independence from the rule of both regional powers, Byzantium and the Caliphate, while it also conformed to a general Eurasian trend to embrace a world religion.

From 862 onwards, the Hungarians (already referred to as the Ungri) along with their allies, the Kabars, started a series of raids from the Etelköz into the Carpathian Basin, mostly against the Eastern Frankish Empire (Germany) and Great Moravia, but also against the Lower Pannonian principality and Bulgaria.

[note 37] Although Benjamin was victorious, his son Aaron II faced another invasion, this time led by the Alans, whose leader had converted to Christianity and entered into an alliance with Byzantium, which, under Leo VI the Wise, encouraged them to fight against the Khazars.

[137][138] A Kievian prince named Oleg, grandson of Jaroslav was reportedly kidnapped by "Khazars" in 1079 and shipped off to Constantinople, although most scholars believe that this is a reference to the Cumans-Kipchaks or other steppe peoples then dominant in the Pontic region.

The afterlife, to judge from excavations of aristocratic tumuli, was much a continuation of life on earth, warriors being interred with their weapons, horses, and sometimes with human sacrifices: the funeral of one tudrun in 711-12 saw 300 soldiers killed to accompany him to the otherworld.

Byzantium began to encourage the Alans to attack Khazaria and weaken its hold on Crimea and the Caucasus, while seeking to obtain an entente with the rising Rus' power to the north, which it aspired to convert to Christianity.

[162] One important condition for mass conversion was a settled urban state, where churches, synagogues or mosques provided a focus for religion, as opposed to the free nomadic lifestyle of life on the open steppes.

"[180] The earliest surviving Arabic text that refers to Khazar Jewishness appears to be that which was written by ibn Rustah, a Persian scholar who wrote an encyclopedic work on geography in the early tenth century.

[188] Modern scholars generally[note 75] see the conversion as a slow process through three stages, which accords with Richard Eaton's model of syncretic inclusion, gradual identification and, finally, displacement of the older tradition.

[200][note 84] Ibn Fadlan recounts specifically an incident in which the king of Khazaria destroyed the minaret of a mosque in Atil as revenge for the destruction of a synagogue in Dâr al-Bâbûnaj, and allegedly said he would have done worse were it not for a fear that the Muslims might retaliate in turn against Jews.

[175] In 965, as the Qağanate was struggling against the victorious campaign of the Rus' prince Sviatoslav, the Islamic historian Ibn al-Athîr mentions that Khazaria, attacked by the Oğuz, sought help from Khwarezm, but their appeal was rejected because they were regarded as "infidels" (al-kuffâr; pagans).

According to the authors, "The Y-chromosome data are consistent with the results of the craniological study and genome-wide analysis of the same individuals in the sense that they show mixed genetic origins for the early medieval Khazar nobility".

[note 98][228][229] In 1932, Samuel Krauss ventured the theory that the biblical Ashkenaz referred to northern Asia Minor, and he identified it as the ancestral homeland of the Khazars, a position which was immediately disputed by Jacob Mann.

[230] Ten years later, in 1942, Abraham N. Polak (sometimes referred to as Poliak), later professor for the history of the Middle Ages at Tel Aviv University, published a Hebrew monograph in which he concluded that the East European Jews came from Khazaria.

[245] In a broad academic perspective, both the idea that the Khazars converted en masse to Judaism and the suggestion they emigrated to form the core population of Ashkenazi Jewry, remain highly polemical issues.

[255] The Kazar hypothesis was further exploited by esoteric fascists such as Miguel Serrano, referring to a lost Palestinabuch by the German Nazi-scholar Herman Wirth, who claimed to have proven that the Jews descended from a prehistoric migrant group parasiting on the Great Civilizations.

The intent of the work, although based on Ḥasdai ibn Shaprūṭ's correspondence with the Khazar king, was not historical, but rather to defend Judaism as a revealed religion, written in the context, firstly of Karaite challenges to the Spanish rabbinical intelligentsia, and then against temptations to adapt Aristotelianism and Islamic philosophy to the Jewish faith.

[270] Cities associated with the Khazars include Atil, Khazaran, Samandar; in the Caucasus, Balanjar, Kazarki, Sambalut, and Samiran; in Crimea and the Taman region, Kerch, Theodosia, Yevpatoria (Güzliev), Samkarsh (also called Tmutarakan, Tamatarkha), and Sudak; and in the Don valley, Sarkel.
