a member of the National Socialist German Workers' party of Germany, which in 1933, under Adolf Hitler, seized political control of the country, suppressing all opposition and establishing a dictatorship over all cultural, economic, and political activities of the people, and promulgated belief in the supremacy of Hitler as Führer, aggressive anti-Semitism, the natural supremacy of the German people, and the establishment of Germany by superior force as a dominant world power. The party was officially abolished in 1945 at the conclusion of World War II.

1930, from Ger. Nazi, abbreviation of Ger. pronunciation of Nationalsozialist (based on earlier Ger. sozi, popular abbreviaton of "socialist"), from Nationalsozialistische Deutsche Arbeiterpartei "National Socialist German Workers' Party," led by Hitler from 1920. The 24th edition of Etymologisches Wörterbuch der deutschen Sprache (2002) says the word Nazi was favored in southern Germany (supposedly from c.1924) among opponents of National Socialism because the nickname Nazi (from the masc. proper name Ignatz, Ger. form of Ignatius) was used colloquially to mean "a foolish person, clumsy or awkward person." Ignatz was a popular name in Catholic Austria, and according to one source in WWI Nazi was a generic name in the German Empire for the soldiers of Austria-Hungary. An older use of Nazi for national-sozial is attested in Ger. from 1903, but EWdS does not think it contributed to the word as applied to Hitler and his followers. The NSDAP for a time attempted to adopt the Nazi designation as what the Germans call a "despite-word," but they gave this up, and the NSDAP is said to have generally avoided the term. Before 1930, party members had been called in Eng. National Socialists, which dates from 1923. The use of Nazi Germany, Nazi regime, etc., was popularized by German exiles abroad. From them, it spread into other languages, and eventually brought back to Germany, after the war. In the USSR, the terms national socialist and Nazi were said to have been forbidden after 1932, presumably to avoid any taint to the good word socialist. Soviet literature refers to fascists.
