Reply To: Who is the new leader of Klal Yisrael?

Joseph,
One Gadol for klal Yisrael has rarely ever happened, one of the reasons is technically, each region had it’s own. The GR”A was mainly excepted in Lithuania and parts of Russia .
At the same time in Poland it was the Noda beYehuda as Gadol.
Distances and borders were a major role in not even knowing some Gadolim, Just to show how the distances effected, the Shagas Aryeh who lived in Lithuania replies in a responsum written to the Bais Efrayim in regards to a Noda BeYehuda he quoted, “I never saw or heard of such sefer nor of the author”, at the very same time when the NB was posek hador in his part of the world.
On the other hand, the Chida never mentions the GR”A but he mentions many others of Europe like the above NB.
