Nachman of Breslov, Ukrainian religious leader, founded the breslov hasidic group (b. 1772)
Nachman of Breslov (Hebrew: נחמן מברסלב), also known as Reb Nachman of Bratslav, Reb Nachman Breslover (Yiddish: רבי נחמן ברעסלאווער), and Nachman from Uman (April 4, 1772 – October 16, 1810), was the founder of the Breslov Hasidic movement.
Reb Nachman, a great-grandson of the Baal Shem Tov, revived the Hasidic movement by combining the esoteric secrets of Judaism (the Kabbalah) with in-depth Torah scholarship. He attracted thousands of followers during his lifetime, and his influence continues today through many Hasidic movements such as Breslov Hasidism. Reb Nachman's religious philosophy revolved around closeness to God and speaking to God in normal conversation "as you would with a best friend". The concept of hitbodedut is central to his thinking.
