During the Third Reich, the Nazis persecuted various groups including Jews, homosexuals, and the disabled, viewing them as incompatible with their ideology of an Aryan master race. This ideology led to forced sterilizations, imprisonment, and systematic extermination of targeted populations, including the notorious Nuremberg Laws that stripped Jews of citizenship. The Kristallnacht pogrom marked a significant escalation in anti-Semitic violence, resulting in widespread destruction and further persecution of Jews in Germany.
