The world has Great Leaders. The Torah World has Manhigim, Gedolei Torah, Roshei Yeshiva, Chassidic Rebbeim, Sefardic Gedolim etc...
The Olam Hatorah has famous Roshei Yeshiva that changed the face of Yiddishkeit and elevated the Torah learning to higher levels.
There have been thru-out the generations Gedolei Torah unknown to our Dor. Some in Europe ... Some in Eretz Yisroel .... Some in America.
