Moetzes Gedolei HaTorah is the supreme rabbinical policy-making council of the Agudat Yisrael and Degel HaTorah movements in Israel; and of Agudath Israel of America in the United States. Members are usually prestigious Roshei Yeshiva or Hasidic rebbes, who are also usually regarded by many Haredi 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.
