Knesseth HaRabbanim HaOrthodoxim BeAmerica - Assembly of Hebrew Orthodox Rabbis of America. Parts I and II. Edited by Yitzchak Leib Epstein. Text in Hebrew, Yiddish and English.

This rabbinic organization was founded in 1920 by Gavriel Zev Margolioth (”Reb Velvele”) as a rival body to the more well established Agudath HaRabbanim, the Union of Orthodox Rabbis of the United States and Canada. The documents and proceedings here indicate that Prohibition issues was the impetus for the establishment of the new assembly; for only an organization sanctioned by the Prohibition Commissioner of the Treasury Department was permitted to designate rabbis to procure and sell wine for sacramental purposes. It seems that the Agudath HaRabbanim was withholding such permits from certain dissident rabbis, who in turn set out to form their own organization, the Knesseth HaRabbanim.
