Lithuanian Jews (known in
Yeshivish as
Litvish (adjective) or
Litvaks (noun)) are
Ashkenazi Jews with roots in the
Grand Duchy of Lithuania (present-day
Belarus,
Lithuania and the northeastern
Suwalki region of
Poland).
The word Litvish means "(Latvian Jews were known as Lettishe). Of main Yiddish dialects in Europe, the Litvishe Yiddish (Lithuanian Yiddish) dialect was spoken by Jews in Lithuania, Belarus, and in the northeastern Suwalki region of Poland.
The characteristically "Lithuanian" approach to Judaism was marked by a concentration on highly intellectual Talmud study. Lithuania became the heartland of the traditionalist opposition to Hasidism, to the extent that in popular perception "Lithuanian" and "mitnagged" became virtually interchangeable terms. In fact, however, a sizable minority of Lithuanian Jews belong(ed) to Hasidic groups, including Chabad, Slonim, Karlin (Pinsk) and Koidanov. With the spread of the Enlightenment, many Lithuanian Jews became devotees of the Haskala (Jewish Enlightenment) movement in Eastern Europe pressing for better integration into European society, and today many leading academics, scientists and philosophers are of Lithuanian Jewish descent.
The most famous Lithuanian institution of Jewish learning was Volozhin yeshiva, which was the model for most later yeshivas. "Lithuanian" yeshivas in existence today include Ponevezh, Telshe, Mir, Kelm, and Slabodka. In theoretical Talmud study, the leading Lithuanian authorities were Chaim Soloveitchik and the Brisker school; rival approaches were those of the Mir and Telshe yeshivas. In practical halakha the Lithuanians traditionally followed the Aruch HaShulchan, though today the "Lithuanian" yeshivas prefer the Mishnah Berurah, which is regarded as both more analytic and more accessible.
