Union of Orthodox Rabbis

The Union of Orthodox Rabbis of the United States and Canada (UOR), often called by its Hebrew name, Agudath Harabonim or (in Ashkenazi Hebrew) Agudas Harabonim ("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.
