Yeah, no. The kagan and some of the aristocracy. Perhaps 50 families or so.
The file and rank Jews in Khazaria were Jews fleeing from Byzantium.
The Khagan converted because for he thought it would be a good idea to have his own Abrahamic religion, since he was the peer of both the emperor and the caliph, and felt it unacceptable to be their underling in case of conversion, for both Christianity and Islam expanded aggressively into his khaganate.
For the Jews it meant security.
