OhAndy, , thank you.
There was plenty of opposition before Hitler became Chancellor in January of 1933. After that any and all opposition was brutally suppressed. Contrarians were silenced, imprisoned, an unknown number killed.
As I said, the early Nazi concentration camps were built originally for civilian political opponents: Communists, Socialists, "sexual deviants", and others. Between 1933 and 1945, 20,000 such camps were built in Germany and in the occupied countries (Poland, the Netherlands for example).
There is a wealth of information on the web, under Nazi Camps, for example. Perhaps you would link pertinent information here. I have trouble deciphering and transmitting long URLs. Thank you.
That's why I make typos, no matter how hard I try not to.
A massive, universal, unstoppable indoctrination of the populace began in 1933. In 1938 there was no more OPEN [/b]opposition. Now the main target were the Jews and their extermination. I choke when I say this, but it is the truth.,
Re question 2 "... did most of the German people share the same sense of hope, security and trust in Adolf Hitler under his presidency and Nazi rule in th 1930s?"
I don't know about most people, I was a child.
In 1931, my father was transferred from the idyllic small town in the Rhineland at the confluence of the Rhine and Moselle Rivers, where I was born, to Mannheim, a large industrial city. We lived in quiet suburb in a handsome house built of lovely sandstone in Jugendstil[=German Art Nouveau) on a corner of main street. We rented the apartment on the first floor (in Europe that means one flight up from the ground floor. The latter is called parterre).
This was two years before Hitler became chancellor.
I remember different groups of people marching by the house, always a man ahead waving a flag. There were different flags, a red one with hammer and sickle, a red-black-gold one (the Socialists), and a red-white-black one (the Nationalists).
"Rowdies", said my mother. "Close the windows! " My father gently explained.
There were also Catholic processions; there was a Catholic party endorsed by the Catholic Church = The ZentrumPartei. Despite its name, "centric" it was not.
Two years later there was no more Catholic party, or any other save the NSDAP, no more processions.
Much worse was in store.
More soon about hope, security and trust.
