While the Nazi Party was around before Hitler joined it(he was, I think, the 19th member? 21st?), it was still in its embryonic stages. You could see the beginnings, but it was Hitler's charisma and his ability to orate that lead him to be the head of the movement, and because it had always been obsessed with the "Leader Principle", whoever was seen as the highest party member dictated what the Will of the Party was.Thanks, but that is not exactly what I was asking.
What do you expect would have happened if Hitler was never born, or never developed an intereste in politics? How much of the Nazi movement is a direct consequence of his personality, and how much was the Zeistgeist? What are the odds that a similar character would have taken his place? How similar, and to what consequences?
As for a never-born Hitler or a less successful one(say, the German government deporting him back to Austria after his failed Putsch), you would've likely have seen a generic Military-Authoritarian state. It would still have sought Anschluss with Austria, and it would have still wanted to regain the eastern & western territories it lost to Poland, France & Belgium at Versailles, but I sincerely doubt there would have been a holocaust.
Antisemitism was prevalent through out all of Europe at the time, but there is a mighty big difference between "I hate Jews" and "Let's kill all the Jews".
For the military, it was simply cultural inertia. The German Army was formed from the nucleus of the Prussian one, where free-thinking was encouraged but orders were meant to be followed to the best of your ability. Von Manstein, when asked by von Tresckow if he would join the plotters, responded "Prussian Field Marshals do not mutiny".Sure. While currently Hitler is universally reviled, it took a long time for people (not only in Germany) to realize that he must be stopped.
As of 1944, even his own high military command basically had to conspire to kill him.
Hitler abused that mindset to his own ends.
As for the people, most find this hard to believe but the ordinary German didn't have much inkling of the Holocaust. Concentration Camps were initially just that, camps to put undesirable people. A place to put trouble-makers & political dissidents and other enemies of the state. They might be worked to death, but it was never for the purpose of destroying an entire people. And even if the average German did find out, the Gestapo's reach was almost infinite. They were one of, perhaps the best Secret Police in history. People worried for their lives and the lives of their loved ones.
At the time it wasn't clear. At the time people saw Hitler as Germany's Mussolini. Nothing more or less. If anything, they saw him as an extremely useful individual. Britain was lenient with Germany regarding rearmament because they wanted a German Shepard to stand guard against the Bolsheviks. A powerful Germany to keep the Soviets out of Central & Western Europe.But how notable was the Nazi regime for the time, anyway? How early did the signs that this wasn't just another relatively acceptable nationalistic regime come, and how clearly? How clear is that even today?
