Hasidic rabbi and teller of tales, founder of the Bratslaver Hasidic sect.

The great-grandson of the Baʿal Shem Tov, the founder of the Hasidic movement, Naḥman was an ascetic from childhood. Married at age 13, he became a self-appointed religious leader and teacher at about age 20. After studying (1798–99) in Tiberius, Palestine, he returned home and declared himself the “true zaddik (tzaddiq)” (righteous man) of his generation, the one who would renew the Hasidic movement. Naḥman gained a following among Hasidim but made enemies among mainstream Hasidic leaders who opposed his messianic presumptions. He moved to Bratslav in 1802, where he led a group of Hasidim.

Naḥman was noted for the parables, folklore, and mythic tales he told to prepare his followers to worship God. Rabbi Nathan Sternharz, his disciple, compiled and wrote down his teachings, which emphasized faith in the zaddik as a father confessor and mediator between God and man; the need to redeem the world from evil through simple faith; prayer, even if in Yiddish instead of Hebrew; repentance through fasting and self-punishment; and religiosity expressed through song and dance.
