The Khazars 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. They created what for its duration was the most powerful polity to emerge from the break-up of the Western Turkic Khaganate. 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'. For some three centuries the Khazars dominated the vast area extending from the Volga-Don steppes to the eastern Crimea and the northern Caucasus.
Atil, also Itil, was the capital of the Khazar Khaganate from the mid-8th century to the late 10th century. Known to have been situated on the Silk Road, in the vicinity of the Caspian Sea, its precise location has long been unknown.
Bulan was a Khazar king who led the conversion of the Khazars to Judaism. His name means "elk" or "hart" in Old Turkic. The date of his reign is unknown, as the date of the conversion is hotly disputed, though it is certain that Bulan reigned some time between the mid-8th and the mid-9th centuries. Nor is it settled whether Bulan was the Bek or the Khagan of the Khazars.
The Schechter Letter, also called the Genizah Letter or Cambridge Document, was discovered in the Cairo Geniza by Solomon Schechter in 1912. It is an anonymous Khazar letter discussing several matters including the wars of the early 940s, involving the Byzantine Empire, the Khazar Khaganate, and Kievan Rus'. Scholars have debated its authenticity.
Arsiyah was the name used for a group of Muslim mercenaries in the service of the Khazar Khaganate. Whether the Arsiyah were a single tribe or composed of Muslims from a number of different tribes is unclear. Also unclear is their origin; many historians regard them as deriving from Khwarazm, but some scholars point to the fact that "As" is the Turkic term for Alans and believe that the Arsiyah were Alanic in origin. Other scholars derive the name from Iranian Auruša (white).
Joseph ben Aaron was king of the Khazars during the 950s and 960s. Joseph was the son of Aaron II, a Khazar ruler who defeated a Byzantine-inspired war against Khazaria on numerous fronts. Joseph's wife was the daughter of the king of the Alans.

Obadiah was the name of a Khazar ruler of the late eighth or early ninth century. He is described as coming from among "the sons of the sons" of Bulan, but whether this should be taken literally to mean that he was Bulan's grandson, or figuratively to imply a more remote descent, is unclear. He was succeeded by his son Hezekiah.
A Khazar ruler during the early 10th century CE, Aaron ben Benjamin was the son of the Khazar king Benjamin. Whether Aaron, like the rest of the Bulanids, was a Khagan or a Bek is an unresolved issue.
An elteber was a client king of an autonomous but tributary tribe or polity in the hierarchy of the Turkic khaganates including Khazar Khaganate.
Baliqchi was a supposed military title used by the Khazar Khaganate. The main piece of support for the term's existence is the historiography of Theophanes the Confessor, which mention a governor of Phanagoria during Justinian II's 705 CE excursion into Khazaria by the name of Balgitzin – which has sometimes been as a Greek corruption of the title baliqchi, but this is unclear. If Balgitzin can be associated with baliqchi, then it may mean "[an executer of a labour/issue] pertaining to a walled town/stronghold", as balık in Old Turkic means "walled town, stronghold", therefore affording a title or a common name for a townwall guardian. Other meanings for baliqchi have been proposed, such as "fisherman", which might imply a connection to a naval force.
The Khazz was the ethnarch of the Muslim community in Khazaria. The Khazz resided in the city of Khazaran. He may have had some authority over the division of the army known as the Arsiyah.

Hezekiah ben Obadiah was a hypothetical ruler of the Khazars, probably in the mid ninth century CE. He was the son of Obadiah, the descendant of Bulan who brought rabbinical scholars to and built yeshivot in Khazaria. Nothing is known about Hezekiah's reign and the historical authenticity and accuracy of the only document mentioning his name has been questioned. As with other Bulanid rulers, it is unclear whether Hezekiah was Khagan or Khagan Bek of the Khazars, although the latter is more likely.
Menasseh ben Hezekiah was a hypothetical Turkic ruler of the Khazars mentioned in the Khazar Correspondence. He probably reigned in the mid to late ninth century CE. He was the son of Hezekiah, the son of Obadiah. Little is known about his reign. Historical authenticity and accuracy of the only document mentioning his name has been questioned. As with other Bulanid rulers, it is unclear whether he was Khagan or Khagan Bek of the Khazars, although the latter is more likely.
Isaac ben Hanukkah was a hypothetical Jewish ruler of the Khazars mentioned in the Khazar Correspondence. He probably reigned in the mid to late ninth century CE. Little is known about his reign. As with other Bulanid rulers, it is unclear whether Isaac was Khagan or Khagan Bek of the Khazars, although the latter is more likely. He was succeeded by his son Zebulun. Historical authenticity and accuracy of the only document mentioning his name has been questioned.
Menasseh ben Zebulun was a hypothetical Jewish ruler of the Khazars mentioned in some extant editions of the Khazar Correspondence. In some versions he is called Moshe or Moses, but this may be a result of the degradation of the text. He probably reigned in the late ninth century CE. Little is known about his reign. As with other Bulanid rulers, it is unclear whether Menasseh was Khagan or Khagan Bek of the Khazars, although the latter is more likely. Historical authenticity and accuracy of the only document mentioning his name has been questioned.

Pax Khazarica is a historiographical term, modeled after the original phrase Pax Romana, applied to the period during which the Khazar Khaganate dominated the Pontic steppe and the Caucasus Mountains. During this period, Khazar dominion over vital trans-Eurasian trade routes facilitated travel and trade between Europe and Asia by such groups as the Radhanites and the early Rus. The originator of the term is unknown but it was in use by scholars as early as the nineteenth century.
Ishad was an Old Turkic word used to designate the highest-ranking Göktürk generals. It is also used in some Arabic sources to describe the Khagan Bek of the Khazars. Brook, citing Golden, proposes that Ishad is a variant of Shad, a Turkic title of Iranian origin.
