I know that German Reich with the leadership of Adolf Hitler was a dictatorship, however I think, at least in some part of history the majority of Germans supported him and his ideologies. This article claims that Hitler was very popular in between Germans. Also this article says the Nazies had a wide range of supporting group.
But, i believe in some point of history the majority of people stop supporting him. I know there were German resistance to Nazism since 1933, but they were individuals or small groups. But, here i am talking about the majority of society.
My questions is, since when Germans stop supporting Hitler? In other word, what made Germans revise about their opinion?
