also Chasidim, "adherents of a conservative Jewish religious movement founded 1750 by Rabbi Israel ben Eliezer Baal Shem Tobh," 1812, from Hebrew hasidhim, literally "pious ones," plural of hasidh "kind, pious." Earlier the Hebrew word was used in reference to an anti-Hellenistic faction during the time of the Maccabean Wars.
