The Khazar rulers adopt Judaism

At some point between the mid-8th and the mid-9th century the Khazar khagan and the ruling nobility adopted Judaism — the only case of a steppe empire choosing it as the religion of its rulers.

The conversion is described, in different versions, by the letter of the Khazar king Joseph to Hasdai ibn Shaprut (the “Khazar Correspondence”, 10th century), the Cambridge (Schechter) document, Arab authors such as al-Masudi, and the Slavonic Life of Constantine (Cyril), who debated with Jews and Muslims at the khagan’s court in 860–861. Joseph’s letter ascribes the decision to King Bulan after a disputation between representatives of three faiths, and a later religious reform to King Obadiah.

The date is disputed. Some historians link the conversion with about 740, when the Khazars reasserted their independence after Marwan’s campaign of 737 had forced the khagan to accept Islam; others with the years around 800 or with 837/838, when coins inscribed “Moses is the messenger of God” were struck; Constantin Zuckerman argued for about 861. How far Judaism spread beyond the ruling elite is also debated: Arab writers describe a multi-faith capital with judges for Jews, Muslims, Christians and pagans.
