Contrary to popular belief, there was a lot of resistance to the Nazi rule within Germany. Unfortunately they did not necessarily have the structure or support that those in their neighbouring countries did. There were groups and many individuals that tried to do things to undermine the party, some even tried to kill Hitler. While some were successful at sowing seeds of doubt with the public, generally most were caught and executed. There was one documented outcry to the Nazi Policies, where not only did all those who participated not get prosecuted or executed, but they actually made the Nazi party change a policy, the Rosenstrasse Protest.
Although there were many groups of people that stood up for what they believed in, I have only covered a few. Some had only slightly different philosophies to Hitler, some opposed him out right. But all stood up for what they believed in, in a society that was scared and controlled by fear and death. To give all you can for others, even if it means your execution is truly a selfless act, and I believe we should be grateful for their sacrifices. For they have helped make the world the place that it is today.
