820 ARCHBISHOP AGOBARD (779-840) (Lyon, Carolingian Empire)
"Proved" in essays that Jews were born slaves and accursed. Agobard forcibly converted Jewish children, offering them or their parents no choice in the matter. This is the first time in France that such an act was recorded. (Until this time Jews were offered the choice of either converting or being expelled or killed - but there was a "choice"). He also urged the sons (especially Lothair) of Charlemagne's successor, Louis the Pious, to revolt. After the revolt (833) he was disposed, but was later reinstated by Louis. Six of his anti-Semitic essays have survived; which are systematically aimed at humiliating and eradicating the Jewish community.
820 - 829 MICHAEL II (Byzantine Empire)
Emperor Michael II came from Phrygia (west central part of Anatolia) . He adopted a liberal and sympathetic policy toward the Jews including lowering taxes. Michael was”accused “of being half Jewish but was probably influenced by a Judeo-Christian sect (the Athinganoi) which was very active in his area. They practiced many Christian traditions yet kept the Sabbath and other Jewish laws, though not circumcision.
