Second, positive law has created the racial meanings that attach to physical features. In a sense, this is the heart of the prerequisite cases, which at root embody the efforts of the courts to inscribe on the bodies of individual applicants the term “White” or “non-White.” These cases established as legal precedent the racial identities of the various faces and nationalities entering the United States at the turn of the century. Again, however, the racial prerequisites to naturalization are not the only laws that explicitly defined racial identities. Almost every state with racially discriminatory legislation also established legal definitions of race. It is no accident that the first legal ban on interracial marriage, a 1705 Virginia act, also constituted the first statutory effort to define who was Black. Regulating or criminalizing behavior in racial terms required legal definitions of race. Thus, in the years leading up to Brown, most states that made racial distinctions in their laws provided statutory racial definitions, almost always focusing on the boundaries of Black identity. Alabama and Arkansas defined anyone with one drop of “Negro” blood as Black; Florida had a one-eighth rule; Georgia referred to “ascertainable” non-White blood; Indiana used a one-eighth rule; Kentucky relied on a combination of any “appreciable admixture” of Black ancestry and a one-sixteenth rule; Louisiana did not statutorily define Blackness but did adopt via its Supreme Court an “appreciable mixture of negro blood” standard; Maryland used a “person of negro descent to the third generation” test; Mississippi combined an “appreciable amount of Negro blood” and a one-eighth rule; Missouri used a one-eighth test, as did Nebraska, North Carolina, and North Dakota; Oklahoma referred to “all persons of African descent,”  adding that the “term ‘white race’ shall include all other persons”; Oregon promulgated a one-fourth rule; South Carolina had a one-eighth standard; Tennessee defined Blacks in terms of “mulattoes, mestizos, and their descendants, having any blood of the African race in their veins”; Texas used an “all persons of mixed blood descended from negro ancestry” standard; Utah law referred to mulattos, quadroons, or octoroons; and Virginia defined Blacks as those in whom there was “ascertainable any Negro blood” with not more than one-sixteenth Native American ancestry.
The very practice of legally defining Black identity demonstrates the social, rather than the natural basis of race. Moreover, these competing definitions demonstrate that the many laws that discriminated on the basis of race more often than not defined, and thus helped to create, the categories they claimed only to elucidate. In defining Black and White, statutory and case law assisted in fashioning the racial significance that by themselves drops of blood, ascertainable amounts, and fractions never could have. In the name of racially regulating behavior, they created racial identities.
- Finkelman, supra, at 2088. According to Finkelman, “This act also made the first stab at defining who was actually black. The law declared that anyone who was a child, grandchild, or great grandchild of a black was a mulatto under the statute. this meant that persons who were of one-eighth African ancestry were black for purposes of Virginia law.” See generally A.
