In the summer of (5543) 1783 the city of Minsk was the stage for a momentous meeting of minds. Orchestrated by Rabbi Shneur Zalman of Liadi – the Alter Rebbe and encouraged by the most influential Rabbinic authority of the time, Rabbi Eliyahu, the Vilna Gaon, “the great debate” attracted the greatest and most venerable Talmudic scholars of Lithuania, and was intended to resolve the ongoing conflict between the Chassidim and their opponents (“Misnagdim”).
After much deliberation the Goan Rabbi Eliyahu had decided that “if “the cult” [as the Chassidim where referred to] are to demand a debate then we are obligated to answer them”, and so Rabbi Schneur Zalman let it be known that he would be present in the city of Minsk on the Shabbos following the 9th of Av and would remain there for two or three weeks thereafter, so that he may answer “anyone with a query or a complaint against the Chassidim or their conduct”.
