For us Muggles it is hard not to notice the similarity between Voldemort's rule and the Nazi regime, or between the Death Eaters and the Nazis.
But we know WWII happened in the world of HP, and that the Nazis probably existed in it as well.
Was Voldemort aware that there once was a Muggle with very similar ideas to his, only directed at Jews and some other classes rather than Muggles?
Do we know of anyone in the wizarding world who ever pointed this out? I recall Dumbledore saying something along these lines in one of the introductions to the extra books, but I don't have them near me.
