The royal descendants of Bulan are referred to by Khazar researchers as Bulanids, though their self-designation is unknown. While Brook assumes this makes Obadiah Bulan's grandson, the Hebrew phrase is less definitive and may allude to a more remote descent. He refers to the reforming Khazar ruler Obadiah as being one of "the sons of the sons of Bulan". In the Khazar Correspondence, King Joseph traces his lineage back to Bulan. In his quest to discover which of the three Abrahamic religions would shape his own religious beliefs, he invited representatives from each to explain their fundamental tenets.

Dunlop was certain that Bulan was a Khagan however, more recent works, such as The Jews of Khazaria by Kevin Brook, assume that he was the Bek due to references to him leading military campaigns. Their king came as far as the bridge over the Kur and ravaged the country, but the taking of Tiflis is not mentioned by the Arab writers (Yaʿḳūbī, ii, 518 Ṭabarī, iii, 648) while the Georgian chronicle says that in the joint reign of the brothers Ioane and D̲j̲uans̲h̲er (718-86?) the K̲h̲āḳān’s general Blučan (in Armenian Bulčʿan) took Tiflis and conquered Kartli.ĭ. Nor is it settled whether Bulan was the Bek or the Khagan of the Khazars.Ī K̲h̲azar invasion of the Abassid Empire took place in 183/799.

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-700s and the mid-800s. Bulan was a Khazar king who led the conversion of the Khazars to Judaism.
