Paul Anton de Lagarde (2 November 1827 – 22 December 1891) was a German biblical scholar and orientalist, sometimes regarded as one of the greatest orientalists of the 19th century.
As a conservative political theorist, Lagarde's strong support of anti-Semitism, vocal opposition to Christianity, racial Darwinism and anti-Slavism are viewed as having been among the most influential in supporting the ideology of fascism and Nazism.His great learning and gifts were curiously mixed with dogmatism and distrust in the activities of others.
In politics, he belonged to the Prussian Conservative party.
