Racial Integrity Act of 1924

In 1924, the Virginia General Assembly enacted the Racial Integrity Act, which reinforced racial segregation by prohibiting interracial marriage and classifying as "White" a person "who has no trace whatsoever of any blood other than Caucasian". The act, an outgrowth of the eugenicist and scientific racist ideology widespread at the time, was pushed by Walter Plecker, a staunch advocate of White supremacist policies and eugenics who held the post of registrar of the Virginia Bureau of Vital Statistics.
