Investigating more than a dozen camps, from the infamous Dachau, Buchenwald, and Sachsenhausen to less familiar sites, Kim Wunschmann uncovers a process of terror meant to identify and isolate German Jews in the period from 1933 to 1939. Drawing on a wide range of previously unexplored archives, this book explains how the concentration camps evolved into a universally recognized symbol of Nazi terror and Jewish persecution during the Holocaust.
