The Nazi's created concentration camps all over Europe in order to carry out Hitler's "Final Solution." Hitler's "Final Solution" was based around exterminating all European Jews. In order to do this, he developed concentration camps in which systematic killing took place.
These killings took on several different faces. This included extermination chambers, mass shootings, and cremating individuals. These extreme acts of physical violence resulted in the death of millions of European citizens.
During WW2 about 350,000 women had joined the military with many having medical roles as nurses and many also helped to drive trucks to transport certain supplies or munitions to the front.
