Overview
The Organization for Jewish Colonization in Russia, commonly known by the transliterated acronym ICOR, was a North American mass organization established in New York City in December 1924. It promoted and financed the settlement of Jews in collective agricultural communities in the Soviet Union. Its work initially focused on Jewish farms in southern Ukraine and Crimea, and later shifted toward the Jewish Autonomous Oblast in the Soviet Far East, commonly known in English as Birobidzhan or Birobidjan. ICOR emerged in response to the severe insecurity experienced by many Jews in Eastern Europe after pogroms, war, displacement, and the social disruption accompanying early Soviet consolidation. Its supporters presented collective agricultural settlement as both a humanitarian project and a way to preserve Jewish communal life, language, and national identity. The organization was also explicitly positioned against Zionism: rather than supporting a Jewish homeland in Palestine, ICOR advocated a Jewish territorial project within the Soviet framework. The group worked with Soviet settlement agencies, particularly KOMZET and OZET, which coordinated and administered Jewish agricultural colonization inside the USSR. The organization drew support from Yiddish-speaking immigrants and their descendants in the United States and Canada. Its fundraising combined contributions from prominent donors with smaller subscriptions solicited through the Yiddish press and affiliated community networks. Julius Rosenwald, the Sears, Roebuck and Company executive and philanthropist, was among its early patrons and contributed more than two million dollars according to accounts summarized in the organization’s historical literature. ICOR also became associated with the Communist Party of the United States and, in Canada, with the Communist Party of Canada. Its positions generally followed the changing international line of the Communist movement. In 1928, when Soviet policy moved away from Jewish settlement in Crimea and toward the creation of a Jewish autonomous territory in the eastern Soviet Union, ICOR redirected its efforts toward Birobidzhan. The organization supported publicity, fundraising, and assistance for prospective settlers. During the 1930s it also participated in anti-Nazi protest activity, supported boycotts of German goods, and raised funds for the International Brigades in the Spanish Civil War. These activities broadened its political profile beyond settlement work but also reinforced its identity as a Communist-front organization. A related American organization, the American Committee for the Settlement of Jews in Birobidjan, known as Ambidjan, was founded in New York on February 27, 1934. Ambidjan concentrated more specifically on promoting and financing emigration to Birobidzhan. It began formal operations in 1935, operated from Madison Avenue in New York, and worked with Soviet officials on the selection and assistance of prospective settlers. William W. Cohen, a former New York congressman and banker, was its principal American organizer and president; Lord Marley served as honorary president. In 1946, ICOR and Ambidjan merged into a unified organization. The merged organization declined rapidly after the Second World War. The Molotov–Ribbentrop Pact had already damaged the standing of Communist-aligned anti-fascist groups, while postwar revelations about Soviet repression and the rise of McCarthy-era anti-Communism made the organization increasingly difficult to sustain in North America. The establishment of Israel in 1948 also strengthened Zionism as the more attractive Jewish national and settlement alternative for many potential supporters. The organization was dissolved in 1951. It remains historically significant as an example of American and Canadian Jewish Communist organizing, Soviet territorialism, and the international campaign surrounding the Birobidzhan project.
History
The Organization for Jewish Colonization in Russia, or ICOR, was founded in New York City in December 1924. It developed among Jewish immigrant and Yiddish-speaking communities that were searching for practical responses to the poverty, persecution, and displacement affecting Jews in Eastern Europe. The organization’s early program combined humanitarian relief, agricultural resettlement, and Jewish territorialism. Instead of advocating emigration to Palestine, it supported the establishment of Jewish collective farms within the Soviet Union. ICOR’s first projects centered on Crimea and southern Ukraine, areas that had formed part of the former Pale of Settlement and contained Jewish populations affected by pogroms, war, urban displacement, and the upheavals of Soviet economic restructuring. The organization raised money in North America and worked in conjunction with Soviet authorities. Its activities complemented those of KOMZET, the official Soviet committee responsible for Jewish agricultural settlement, and OZET, a related society that promoted Jewish settlement and agricultural labor. The organization’s supporters believed that agricultural colonization could provide both economic security and a basis for preserving Jewish collective identity. Yiddish-language newspapers and community networks helped solicit contributions from ordinary donors, while wealthy American Jews supplied larger gifts. Julius Rosenwald was an early patron and was reported to have contributed more than two million dollars. This broad donor base allowed ICOR to present itself as a mass Jewish movement, although its political orientation was increasingly tied to Communist organizations. Soviet policy changed in 1928, when the government abandoned the idea of developing Crimea as the main center of Jewish territorial settlement and instead promoted a Jewish autonomous territory in the eastern USSR. ICOR followed this policy shift and made Birobidzhan the principal focus of its publicity and fundraising. The proposed settlement was far from the established Jewish centers of Europe and North America, and its climate, infrastructure, and economic conditions posed significant practical difficulties. Nevertheless, ICOR presented Birobidzhan as a possible collective Jewish homeland within a socialist state. In North America, ICOR became associated with the Communist Party, USA, and its Canadian counterpart. It generally reflected the international Communist movement’s changing positions. During the 1930s, it participated in protests against Nazi Germany, promoted boycotts of German products, and raised funds for the International Brigades during the Spanish Civil War. These activities linked the organization’s settlement program to a broader anti-fascist agenda, but they also made it more vulnerable to political criticism and shifting Communist policies. Ambidjan was founded in New York on February 27, 1934, to provide a more specialized American fundraising and solidarity vehicle for the Birobidzhan project. The founding meeting was held at the Ritz-Carlton Hotel and featured Lord Marley, a British Labour politician and prominent advocate of the Birobidzhan project. William W. Cohen, a banker, stockbroker, and former member of Congress, became the principal American organizer and president. Formal operations began in 1935 from an office at 285 Madison Avenue. Lord Marley served as honorary president. Jacob M. Budish played an important behind-the-scenes role in Ambidjan. He was connected to the Communist Party, worked for Amtorg, the Soviet foreign-trade organization in New York, and had contacts with Soviet diplomatic and administrative officials. In 1935 he visited Birobidzhan and discussed the organization’s possible role with Soviet authorities. Following those discussions, Ambidjan received permission to help subsidize the emigration of European Jews. Prospective settlers, particularly from Poland, Lithuania, Romania, and Germany, were to be selected in consultation with Soviet officials, and Ambidjan planned to provide a fixed grant for each approved family. Ambidjan attracted members from varied social backgrounds, including middle- and upper-class Americans and some non-Jews. Its dues were set at five dollars, reflecting an effort to combine organized mass membership with philanthropic support. Although ICOR and Ambidjan had different emphases, their programs overlapped substantially. They merged in 1946, forming a unified organization at a time when the future of Birobidzhan and the political legitimacy of Soviet-aligned Jewish initiatives were increasingly contested. The movement’s decline accelerated after the Second World War. The Molotov–Ribbentrop Pact had weakened the credibility of Communist-aligned anti-fascist organizations, and the broader American anti-Communist climate of the late 1940s and early 1950s made fundraising and public organizing more difficult. The creation of Israel in 1948 also gave Jewish national aspirations a more compelling and internationally recognized focus for many people who might otherwise have considered territorialist alternatives. ICOR’s association with Soviet Communism, together with the limited appeal and difficult conditions of Birobidzhan, ultimately prevented its recovery. The organization was dissolved in 1951.
