My history teacher told me that "most historians agree that Hitler had a Jewish grandparent." Is this true? If not, is this a popular belief among certain historians or are his beliefs unfounded?
I am sorry to have to break this to your teacher and you, but most historian do not believe Adolf Hitler had a Jewish grandparent. To say so is utter nonsense and something he or she likely heard on the history channel. This was propaganda spread around due to his mother's out-of-wedlock child and naturally because nothing would be more hypocrital if it were true.
