- Jews: The Nazis considered Jewish people to be inferior to Aryans, and they systematic targeted and persecuted them through measures such as the Nuremburg Laws, the establishment of concentration and extermination camps, and the implementation of the "final solution" that resulted in the murder of approximately 6 million Jewish individuals.

This program involved the involuntary euthanasia of thousands of disabled people, including children and adults, in psychiatric hospitals and institutions.
