A Moetzes Gedolei HaTorah (Hebrew: מועצת גדולי התורה‎, "Council of [great] Torah Sages") is the supreme rabbinical policy-making council of the Agudat Yisrael and Degel HaTorah movements. Rabbis sitting on the various Moetzos are usually either one of the more prestigious Roshei Yeshiva (heads of yeshivas) or Hasidic rebbes who are also usually regarded by many ultra-Orthodox Jews to be the Gedolim ("great/est") sages of Torah Judaism. Before the Holocaust it was the supreme authority for the World Agudath Israel in Europe. https://en.wikipedia.org/wiki/Moetzes_Gedolei_HaTorah
