How does Nietzsche's philosophy affect 20th century history?

Many political leaders of the twentieth century were at least superficially familiar with Nietzsche's ideas. However, it is not always possible to determine whether or not they actually read his work. Regarding Hitler, for example, there is a debate.

Some authors claim that he probably never read Nietzsche, or that if he did, his reading was not extensive. Nevertheless, others point to a Hitler's speech in Hitler's Table Talk, where the dictator mentioned Nietzsche when he spoke about what he called "great men", as an indication that Hitler may have been familiarized with Nietzsche's work. Other authors like Melendez (2001) point out to the parallelism between Hitler's and Nietzsche's titanic anti-egalitarianism, and the idea of the "übermensch", a term which was frequently used by Hitler and Mussolini to refer to the so-called "Aryan race", or rather, its projected future after Fascist engineering.

Alfred Rosenberg, an influential Nazi ideologist, also delivered a speech in which he related National Socialism to Nietzsche's ideology. Broadly speaking, the Nazis made very selective use of Nietzsche's philosophy, and eventually, this association caused Nietzsche's reputation to suffer following World War II.

The Übermensch (German for "Overman, Overhuman, Above-Human, Superman, Superhuman, Ultraman, Ultrahuman, Beyond-Man") is a concept in the philosophy of Friedrich Nietzsche. The term Übermensch was used frequently by Hitler and the Nazi regime to describe their idea of a biologically superior Aryan or Germanic master race; a form of Nietzsche's Übermensch became a philosophical foundation for the National Socialist ideas. Their conception of the Übermensch, however, was racial in nature.

The Nazi notion of the master race also spawned the idea of "inferior humans" (Untermenschen) which could be dominated and enslaved.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
