The Union of Orthodox Rabbis of the United States and Canada (UOR), often called by its Hebrew name, Agudath Harabonim or Agudas Harrabonim ("union of rabbis"), was established in 1901 in the United States and is the oldest organization of Orthodox rabbis in the United States. It had been for many years the principal group for such rabbis, though in recent years it has lost much of its former membership and influence. History The Agudath Harabonim was formed in 1902, to espouse a strictly traditionalist agenda. Its founders were concerned with the Americanized, acculturated character of even the relatively traditional wing of local Jewry, exemplified by the Orthodox Union (OU), which had formed five years earlier, and the Jewish Theological Seminary of America. There were two distinct groups within the American Orthodox rabbinate: the Eastern European and the Western European and American-born: "The Americans were English-speakers, often had a secular education, and competed with Reform (and later Conservative) movements for the heart of the modern American Jew. European transplants were often Yiddish-speaking with barely any English skills, trained exclusively in rabbinics, and would be termed Haredi today, and had a stronger affinity to the entire body of religious texts; they were there to maintain standards." Though there were American scholars trained in the European path, and European schools that supported secular scholarship, most rabbis belonged to one camp or the other. To the Eastern Europeans, the OU and its later affiliated Rabbinical Council of America, were dangerously accommodationist and lacking in both scholarship and piety. Their credentials were rarely recognized, if at all, by the UOR. The Eastern Europeans needed a fellowship to promote their ideas and raise political capital, and the Agudath Harabanim served that need. The UOR leadership was willing to tolerate the OU in urgent needs, such as kosher supervision. The Agudath Harabonim initially started raising standards in New York and elsewhere, but had some trouble getting the butchers and in line. Mendes and his OU brethren in New York lent them assistance in this area. Among the main founding rabbis of the Agudath Harabonim were Bernard Levinthal, Moshe Zevulun Margolies (known as "Ramaz"), Moshe Yisrael Shapiro; and S. A. Joffee. Margolies was from Europe, and equally at ease in Yiddish and English, had feet in both camps, with a personality well suited for the modern American congregation.
