Note 1344 — Chapter XII · REGIONAL GEOGRAPHY
Reading edition
This belief in the increase of Jewish population in these regions may possibly have been connected in some way with knowledge of the conversion of the Khazars to Judaism in the eighth century. See Carmoly, Itinéraires, 1847, pp. 3–112, and S. Schechter, An Unknown Khazar Document, in: Jewish Quarterly Review, vol. iii (N. S.), London, 1912, pp. 181–219.
