The Nazi Party, officially the National Socialist German Workers' Party (German: Nationalsozialistische Deutsche Arbeiterpartei or NSDAP), was a far-right political party in Germany active between 1920 and 1945 that created and supported the ideology of Nazism. Its precursor, the German Workers' Party (Deutsche Arbeiterpartei; DAP), existed from 1919 to 1920. The Nazi Party emerged from the extremist German nationalist, racist and populist Freikorps paramilitary culture, which fought against the communist uprisings in postWorld War I Germany. The party was created to draw workers away from communism and into vlkisch nationalism. Initially, Nazi political strategy focused on antibig business, anti-bourgeois, and anti-capitalist rhetoric. This was later downplayed to gain the support of business leaders, and in the 1930s the party's main focus shifted to antisemitic and anti-Marxist themes.Pseudoscientific racist theories were central to Nazism, expressed in the idea of a "people's community" (Volksgemeinschaft). The party aimed to unite "racially desirable" Germans as national comrades, while excluding those deemed to be either political dissidents, physically or intellectually inferior, or of a foreign race (Fremdvlkische). The Nazis sought to strengthen the Germanic people, the "Aryan master race", through racial purity and eugenics, broad social welfare programs, and a collective subordination of individual rights, which could be sacrificed for the good of the state on behalf of the people. To protect the supposed purity and strength of the Aryan race, the Nazis sought to exterminate Jews, Romani, Poles and most other Slavs, along with the physically and mentally disabled. They disenfranchised and segregated homosexuals, black people, Jehovah's Witnesses, and political opponents. The persecution reached its climax when the party-controlled German state set in motion the Final Solutionan industrial system of genocide which achieved the murder of around 6 million Jews and millions of other targeted victims, in what has become known as the Holocaust.Adolf Hitler, the party's leader since 1921, was appointed Chancellor of Germany by President Paul von Hindenburg on 30 January 1933. Hitler rapidly established a totalitarian regime known as the Third Reich. Following the defeat of the Third Reich at the end of World War II in Europe, the party was "declared to be illegal" by the Allied powers, who carried out denazification in the years after the war both in Germany and in territories occupied by Nazi forces. The use of any symbols associated with the party is now outlawed in many European countries, including Germany and Austria.

The German Workers' Party (German: Deutsche Arbeiterpartei, DAP) was a short-lived far-right political party established in Weimar Germany after World War I. It was the precursor of the Nazi Party, which was officially known as the National Socialist German Workers' Party (German: Nationalsozialistische Deutsche Arbeiterpartei, NSDAP). The DAP only lasted from 5 January 1919 until 24 February 1920.
