Graves of mental patients killed by the Nazis at Hadamar, Germany. To stop "unworthy life" from "weakening" the race, the physically and mentally handicapped are first subjected to a campaign of enforced sterilization. In 1939, Hitler orders the mass killings of patients in psychiatric hospitals. 80,000 to 100,000 people are killed until 1941, when the "action mercy death" is opposed by the churches and stopped.
