German Freethinkers League

The German Freethinkers League ('Deutscher Freidenkerbund') was an organisation founded in 1881 by the materialist philosopher and physician Ludwig Büchner to oppose the power of the state churches in Germany. Its aim was to provide a public meeting-ground and forum for materialist and atheist thinkers in Germany.

By 1885 the group had 5,000 members. The first organization of its sort founded in Germany, by 1930 the German Freethinkers League had a membership numbering some 500,000. The League was closed down in the spring of 1933, when Hitler outlawed all atheistic and freethinking groups in Germany. Freethinkers Hall, the national headquarters of the League, was then converted to a bureau advising the public on church matters.
