I understand that there was widespread support for the Nazis, but I expect there were many local governments who were not sympathetic to the Nazi cause when they made their power play. What happened to these governments and their officials? Were the governmental powers of Germany more centralized under the Nazis or did they still rely on city governments to manage themselves?
They were kept at the beggining, simply being lined with NSDAP and other people into their leaderships (ex. Göring in Prussia). Later on when the Nazis seized full control of the nation they dismantled the local governments in favor of the Gau system, in which a Gauleiter of the party was the highest official in that region.
