740 ABU ISA AL-ISFAHNI " FALSE PROPHET" (Ispahan, Persia)
Aka Isaac ibn Jacob al-Isfahani. Although he did not claim to be the Messiah, (rather the (Dai) precursor to the Messiah), he began to preach a national Messianic movement, much to the anger of Caliph Marwan II (744 - 750) and Al-Mansur (d. 775). It is likely that the upheaval in the Moslem world prompted his belief that the great war of Gog and Magog was upon them, signifying the end of days. His sect the first in Judaism since destruction of the temple, was known as the Isawiyya (Isawites) and had slight deviations from traditional Judaism. He banned divorce, and instituted additional prayers, but kept the traditional calendar. Although he was killed in his uprising against the Caliph Al -Mansur, his sect continued for about 200 years.
Archbishop of York ordered all “good Christians" not to eat together with a Jew.
740 - 1259 KINGDOM OF KHAZAR
The King Bulan converted his people to a vague form of Judaism ("religion of Abraham") after ordering a disputation between the three major monotheistic faiths. Ibn Shaprut, the
foreign minister for Abd ar-Rahman of Cordova, corresponded with King
Joseph (960). Most of our knowledge of the Khazars is based on these
letters. The Khazars were eventually overcome by the Mongols under Genghis
Khan. With the spread of Christianity by the Russians, many Khazars were
forcibly baptized. The rest fled. Some went into northern Hungary where
villages still have names such as Kozar and Kozardie. Tshagataish, the
language of the Khazar Jews, is spoken by the few remaining Jewish
Krimtchaki of the Crimea. The Khazars' campaign against the Muslims
(730-740) succeeded in checking the Muslim advance on the eastern flank of
Europe. The Khazars succeeded in defending themselves for 500 years against
Muslims, Byzantines and Russians.
