Daniel Solomon Zion was an Orthodox rabbi, Kabbalist and political activist. Zion moved to Sofia, Bulgaria, as a shochet and cantor. Bulgaria's Jewish community at the time was almost completely assimilated, and there were no ultra-Orthodox communities in the country during World War II. In 1950, after emigrating to Israel, Zion was removed from his position on the local rabbinical court for his newfound belief that Jesus of Nazareth was the Jewish Messiah.
