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.
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. King Joseph's Reply claimed that Obadiah strengthened Rabbinic Judaism and Hebrew proficiency in Khazaria by building synagogues and schools and inviting Jewish sages to the country. In Sefer ha-Ittim, Judah ben Barzillai's list of Khazar Jewish kings lacked Obadiah's name, and several scholars have concluded from this that Obadiah was a fictional character. He was succeeded by his son Hezekiah.

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.
