This document summarizes the rise of Nazi ideology in Germany in the early 20th century, including their belief that Jews and other groups were subhuman. It describes how the Nazi party gained power and eliminated political opposition, passing laws to strip Jews of rights. As Hitler's power expanded across Europe, ghettos and camps were established where Jews were imprisoned and subjected to atrocious conditions. Resistance was difficult due to collective punishment policies. The document concludes by noting survivors' concerns that the lessons of this history may be forgotten.
