1161 CE
Many Khazars have evidently remained Jews, even after the final fall of Khazaria in the eleventh century.
Abraham ibn Daud, writing Sefer ha-Qabbalah (The Book of Tradition) in the year 1161, says that he met Khazar students in person while in Toledo, Spain and that they were rabbinical Jews.
