Nazism, or National Socialism in full, is the ideology and practice associated with the 20th-century German Nazi Party and state as well as other related far-right groups. It was also promoted in other European countries with large ethnic German communities, such as Czechoslovakia, Hungary, Romania and Yugoslavia. Usually characterised as a form of fascism that incorporates scientific racism and antisemitism, Nazism originally developed from the influences of pan-Germanism, the Völkisch German nationalist movement and the anti-communist Freikorps paramilitary culture in post-First World War Germany, which many Germans felt had been left humiliated by the Treaty of Versailles. German Nazism subscribed to theories of racial hierarchy and social Darwinism; the Germanic peoples—also referred to as the Nordic race—were considered to be the purest representation of Aryanism, and therefore the master race. Opposed to both capitalism and Marxism, Nazism aimed to overcome social divisions, with all parts of a racially homogeneous society cooperating for national unity and regeneration and to secure territorial enlargement at the expense of supposedly inferior neighbouring nations.
