THE JEWISH COMMUNIST movement, active within the Canadian Jewish community for some three decades, included various groups whose main aim was to provide support for the Soviet project to establish a Jewish socialist republic in the Birobidzhan region in the eastern USSR. One of these groups, the Organization for Jewish Colonization in Russia (Yidishe Kolonizatsye Organizatsye in Rusland), known by its transliterated acronym as the ICOR, was founded in the United States in 1924, and was also active within the Canadian immigrant working-class milieu; its members were mainly first and second generation Yiddish-speaking Jews of east European origin. Little has been published about the ICOR in the us, and even less is known about its Canadian counterpart. Erna Paris, who devotes three chapters to the Canadian Jewish Communist movement in her book Jews: An Account of Their Experience in Canada, has one passing reference to the ICOR, though Gerald Tulchinsky, in his Branching Out: The Transformation of the Canadian Jewish Community, does devote over two pages to it.(1) Other histories of the Communist movement or the Canadian Jewish community ignore it altogether. This research note is therefore very much a preliminary undertaking; there remains much "digging" still to be done.
