The Nazis claimed that Bismarck was unable to complete German national unification because Jews had infiltrated the German parliament and they claimed that their abolition of parliament had ended this obstacle to unification. Using the stab-in-the-back myth, the Nazis accused Jews—and other populations who it considered non-German—of possessing extra-national loyalties, thereby exacerbating German antisemitism about the Judenfrage (the Jewish Question), the far-right political canard which was popular when the ethnic Völkisch movement and its politics of Romantic nationalism for establishing a Großdeutschland was strong.

If, up to now, we had interpreted our fate only as a privation of liberty, our experience changed rapidly. We had to jump down from the truck without the aid of a chair, and the request for a helping hand was denied with abuse. One of our comrades, an older man lacking the agility of youth, fell in this enforced jump and hurt the back of his head so badly that his skin had to be sewed with several stitches. Hardly were we standing on the ground when a pack of young men in S.S. uniforms, with yells and abuse, chased us to the other end of the large, inner, so-called inspection ground, which is surrounded by the barracks of the prisoners. Those who couldn't run fast enough were kicked.
Heinrich Himmler's Schutzstaffel (SS) took full control of the police and the concentration camps throughout Germany in 1934–35. Himmler expanded the role of the camps to hold so-called "racially undesirable elements", such as Jews, Gypsies/Romanis/Sintis, Serbs, Poles, disabled people, and criminals. The number of people in the camps, which had fallen to 7,500, grew again to 21,000 by the start of World War II and peaked at 715,000 in January 1945.
