Drapetomania

It is a term coined by the early 19th century American physician Samuel A. Cartwright to explain the mental disease that made certain enslaved Blacks run away. In Cartwright’s opinion, Blacks were naturally submissive and better off under the control of white masters. He believed that those who tried to escape must have been suffering from a mental disorder that could be solved by “whipping the devil out of them.” Cartwright also claimed that drapetomania could be cured by treating the enslaved Blacks like children “with care, kindness, attention and humanity.”
