The Deutschvölkischer Schutz- und Trutzbund was the largest and the most active antisemitic federation in Germany after the First World War, and an organisation that formed a significant part of the völkisch movement during the Weimar Republic (1918–1933), whose democratic parliamentary system it unilaterally rejected. Its publishing arm issued books that greatly influenced the opinions of Nazi Party leaders such as Heinrich Himmler. After the organisation folded in around 1924, many of its members eventually joined the Nazis.

Theodor Fritsch was a German publisher and journalist. His antisemitic writings did much to influence popular German opinion against Jews in the late 19th and early 20th centuries. His writings also appeared under the pen names Thomas Frey, Fritz Thor, and Ferdinand Roderich-Stoltheim.
