Vilna Gaon

Rabbi Elijah ben Solomon Zalman, known as the Vilna Gaon (Gra), was one of the most influential Jewish scholars of the 18th century, renowned for his exceptional knowledge of the Talmud, Hebrew Bible, Jewish law, and Kabbalah.

Based in Vilnius, Lithuania, he emphasized rigorous Torah study and became a leading opponent of the emerging Hasidic movement. His followers, known as Mitnagdim ("opponents"), defended traditional rabbinic scholarship against what they regarded as problematic Hasidic innovations.

His teachings profoundly influenced Lithuanian Jewish religious culture, the development of modern yeshivot, and the scholarly traditions that continue to shape Orthodox Judaism today.
