With the rise of right wing extremists, including neo-Nazis, I see it often said on social media that the German people of the 1920s and 1930s did little if anything to oppose Adolf Hitler and the National Socialist Party’s rise to power. This is untrue. There was a lot of opposition to the Nazis rise to power, opposition that the Nazis spent much time and effort to overcome. Ideally you should read this history to see this, whether you read works by AJP Taylor, Ian Kershaw, John Toland, Joachim Fest, or others (but not David Irving). For a start, you can read this: Adolf Hitler’s rise to power, beginning with the Beer Hall Putsch. As you read along, you can see many opposed to the rise of the Nazi party. You can argue that they were ineffective: you cannot argue that they did not exist. Many of the opponents were killed (members of the Red Front) and many others, like Ernst Thälmann, were sent to concentration camps. Some fled, others became silent, and still others become supporters. Many died in the war to come.
The Nazis were supported, of course: that is how they managed to be in a position to take over power in the first place. But the idea that they met with little or no opposition is wrong.
