The Eugenics Board of North Carolina (EBNC) was a State Board of the state of North Carolina formed in July 1933 by the North Carolina State Legislature by the passage of House Bill 1013, entitled 'An Act to Amend Chapter 34 of the Public Laws of 1929 of North Carolina Relating to the Sterilization of Persons Mentally Defective'. This Bill formally repealed a 1929 law, which had been ruled as unconstitutional by the North Carolina Supreme Court earlier in the year.
