The Musar movement (also Mussar movement) is a Jewish ethical, educational and cultural movement that developed in 19th century Lithuania, particularly among Orthodox Lithuanian Jews. The Hebrew term (מוּסַר), is adopted from the Book of Proverbs (1:2) describing moral conduct, instruction or discipline, educating oneself on how one should act in an appropriate manner. The term was used by the Musar movement to convey the teachings regarding ethical and spiritual paths. The Musar movement made significant contributions to Musar literature and Jewish ethics. The movement has been revived in the 21st century amongst Jews of all denominations, particularly in the United States.
The Musar movement arose among non-Hasidic Misnagdim Orthodox Lithuanian Jews as a response to the social changes brought about by the Enlightenment, and the corresponding Haskalah movement among many European Jews. In this period of history, anti-Semitism, assimilation, and the impoverished living conditions of many Jews in the Pale of Settlement caused severe tension and disappointment. Many of the institutions of Lithuanian Jewry were beginning to break up. Religious Jews feared that their way of life was slipping away from them, observance of traditional Jewish law and custom was on the decline, and even those who remained loyal to the tradition were losing their emotional connection to its inner meaning and ethical core.
The founding of this movement is attributed to Rabbi Yisrael Lipkin Salanter (1810–1883), although the roots of the movements drew on ideas previously expressed in classical rabbinical literature.
Israel Salanter
Yisrael Lipkin Salanter, a promising young rabbi with exceptional knowledge of Jewish law living in Salantai, Lithuania, was initially inspired to dedicate his life to the cause of spreading Musar by his teacher Rabbi Yosef Zundel Salant (1786–1866). Zundel Salant was a student of rabbis Chaim Volozhin and Akiva Eiger, whose profoundly good-hearted and humble behavior and simple lifestyle attracted Yisrael Salanter's interest.
