These laws make slavery permanent for "Negroes," "mulattoes," and "Indians" by defining these people as "real estate." The slave codes define anyone who has 1/8 African parentage as "Black," and anyone who has 1/2 Native parentage as "Native." This is the origin of the "one-drop" rule for African ancestry, and the "1/2 or more" rule for Natives, which later becomes the basis for "blood quantum." "White" continues to be defined as a synonym for "Christian" and "English," but also as "not-Black" and "not-Indian." The laws contain many other rulings, including prohibiting anyone from transporting an enslaved person or servant out of the colony.
