Misnagdim was a religious movement among the Jews of Eastern Europe which resisted the rise of Hasidism in the 18th and 19th centuries. The Misnagdim were particularly concentrated in Lithuania, where Vilnius served as the bastion of the movement, but anti-Hasidic activity was undertaken by the establishment in many locales. The most severe clashes between the factions took place in the latter third of the 18th century; the failure to contain Hasidism led the Misnagdim to develop distinct religious philosophies and communal institutions, which were not merely a perpetuation of the old status quo but often innovative. The most notable results of these efforts, pioneered by Chaim of Volozhin and continued by his disciples, were the modern, independent yeshiva and the Musar movement. Since the late 19th century, tensions with the Hasidim largely subsided, and the heirs of Misnagdim adopted the epithet Litvishe or Litvaks.

Jewish religious movements, sometimes called "denominations", include diverse groups within Judaism which have developed among Jews from ancient times. Today in the west, the most prominent divisions are between traditionalist Orthodox movements and modernist movements such as Reform Judaism originating in late 18th century Europe, Conservative originating in 19th century Europe, and other smaller ones, including the Reconstructionst and Renewal movements which emerged later in the 20th century in the United States.
