It is a pejorative way of referring to the NSDAP (Nationalsozialistische Deutsche Arbeiter Partei, "National Socialist German Workers' Party"), a political, social and even philosophical movement that ruled Germany between 1933 and 1945, and which ended with World War II. It became a dictatorial, expansionist government, and by its ideology also genocidal, especially against the Jewish community. The Nazi acronym was coined by the writer and opposition journalist Konrad Heiden, inspired by the popularized acronym for the Social Democratic Party (Sozi), but also taken from the nickname given to the somewhat ignorant farmers of Bavaria (place of origin of National Socialism), where the name Ignatz ("Ignacio") was very common with its hypocoristic "Natzi", which was used as the "palette" in Spain. See anti-Semitism.
