1703 August 28, ALEINU PRAYER BANNED (Brandenberg, Germany)
The Aleinu prayer was prohibited in much of Germany. The Aleinu, composed by Rav, one of the great Talmudists (d. 247), had been part of the ritual prayer for almost 1500 years. It served as a focal point for anti-Jewish attacks. Although the wording "For they bow down to emptiness and vanity and to a God that cannot save" was taken from Isaiah (45:20) and referred to idol worshipers, some Christian leaders claimed it was an attack on Christianity. The prayer was eventually entirely eradicated from the Ashkenazi siddur and only reprinted recently.
