Answer:
President Lincoln's First Inaugural Address focused on reassuring the Southern states that the president would not try to strip them of their slaves and that he would try to find a way to help them secure slavery if it would make them happy.
They used them to keep the people who they captured. They captured these people because they either were or looked like Jews. These people were put under harsh conditions going to the concentration camps. They also kept prisoners of war in there. Obviously, nobody wanted to go there. If you want to know more look up Anne-Frank's story. She wrote everything she lived during the time Hitler ruled. She died though and didn't make it out alive. She also went to a concentration camp if I remember correctly.
Hope this helps!
