What is the origin of Nazi?

Nazism sprouted in Weimar Republic after World War I, and it was the product of sharp contradictions inside and outside Germany, so people also called it German Nazi. At that time, Germany was faced with the problems of war responsibility and war compensation, as well as the problem of moving out of the residence of non-Germans. The economy was in trouble and national feelings suffered setbacks. Hitler and others took advantage of the German people's hatred of the Treaty of Versailles and the economic crisis to turn nationalism into national revenge and form Nazism. German Nazism first pointed its finger at Jews in China, claiming that Aryan-Germans in northern Europe were a race endowed with "ruling power" by God, while Jews were inferior and should be eliminated and extinct. After the success of anti-Semitism, Nazism declared that the world was a jungle where the law of the jungle prevailed and the survival of the fittest was eliminated. All ethnic groups should win in the fierce competition for survival, carry out foreign aggression and expansion, and lead the world to war and disaster.
