During the
German revolution of 1918–1919, the Bavarian Peasants' League supported
Kurt Eisner and the
Bavarian Soviet Republic. Under Eisner's direction, Karl Gandorfer, who headed the BB from 1919 to 1932, established a parliamentary farmers' council parallel to the
workers' and soldiers' councils that had taken over across Germany, including in Bavaria. As head of the council, Gandorfer was a member of Eisner's provisional government and filled the 50-member body almost exclusively with members of the BB's left wing.
BVP members led the chamber until 1925, at which point Karl Prieger of the BB took over until 1933. In an attempt to expand its political base into the non-agricultural middle class, the BB changed its name to the Bavarian Peasants' and Small Businesses' League () in 1922, but it had only limited success. Its best results in the Bavarian
Landtag came in 1928 when it won 11.5% of the vote and seated 17 members. The BB provided the Bavarian agriculture minister in six cabinets. From 31 March to 22 November 1922,
Anton Fehr of the BB was minister of food and agriculture in the national government's
second Wirth cabinet, but In the
Reichstag the party never had more than a minor presence and needed to form alliances with other parties in order to achieve parliamentary strength. The BB's support dropped sharply in both the Bavarian
Landtag and the Reichstag elections after 1930. Most of the party's leadership continued to support the Republic after the Nazis came to power in 1933, but many members and lower party officials shifted to the
Nazi Party or, to a lesser extent, the Bavarian People's Party. On 11 April the BB dissolved and urged its members to join Nazi farmers' organizations. == Election results ==
