The “one drop rule” of race refers to the belief that a mere drop of African ancestry makes one “black”—no matter how “white” one’s appearance. This pseudoscientific concept, still commonly believed throughout the United States and among people of various ethnic and racial backgrounds, reinforces the idea that a white person who has even one African ancestor somehow is “passing” for white. However, legal cases that involved race during an era in which being classified as a “Negro” severely circumscribed one’s civil rights reveal that questions about racial identity were anything but black and white.
Historically, one of the many paradoxes of Southern race-based society was the co-existence of the “one drop rule” alongside contradictory legal definitions of whiteness. In Mississippi and North Carolina, for example, a person with less than one-eighth African ancestry was legally defined as white. The legal criteria for determining one’s race sometimes—but certainly not always—prevailed over the one drop rule in cases involving the marital rights of mixed-race people.
For example, in 1949, the Mississippi Supreme Court reversed and remanded Davis Knight’s 1948 conviction* for miscegenation (marrying across the color line) on grounds that the prosecution had failed to prove that Knight had at least one-eighth African ancestry. Challenged by Knight’s aggressive defense lawyer, Quitman Ross, the High Court agreed that the “one drop rule” could not be the determinant of a citizen’s legal status. Davis Knight was deemed legally white and therefore legally married.
Davis Knight’s courtroom victory proved that the disjuncture between social custom and state law might favorably impact a person’s fate. Conversely, in an 1888-1892 North Carolina case, Hopkins, et al, vs Boothe, et al,* Ann Bowers Boothe was deprived of her late husband’s property based on hearsay evidence that she was the daughter of a white woman and a former slave. Even though her alleged father’s nickname, “Red,” indicated his own mixed-race background, and even though the one-eighth law was discussed, Ann’s degree of African ancestry (if indeed, she had any) did not determine the outcome of the case. Rather, the one drop rule prevailed.
An 1877 North Carolina divorce case, Long vs. Long,* reveals the grip of racialist thinking on judges who presided over the South’s transition from race-based slavery to race-based segregation. In a case seemingly not about interracial mixing at all, a white man, James C. Long, sued his white wife Teresa for divorce on grounds she had been pregnant by another man at the time of their marriage. Denied a divorce by the lower court, Long appealed to the North Carolina Supreme Court and was again denied.
Justice William Blount Rodman, however, issued a lengthy dissent from the bench. Although Teresa Long had given birth to a white child, Justice Rodman raised the possibility that an adulterous woman such as she might have been carrying a black man’s child. Citing “scientific” evidence that makes our head swim today, Justice Rodman claimed that “physiologists tell us” that once a white woman has given birth to a mixed-race child, her blood “has been tainted by mingling with that of her first child, and she is incapable of bearing children that will not show mixture of African blood in appearance or character” (italics mine). The courts, argued Rodman, must therefore allow divorce in cases where the bride was already pregnant, or “man has lost the common right lawfully to continue his pure race.”
Such was the imputed power of one drop of African blood! Did this highly-educated Supreme Court judge truly believe that an interracial pregnancy had the power to “taint” the blood stream of a white woman? Given the racial theories of his time, he most likely did. But Justice Rodman took the “one drop rule” a step further than most by arguing in essence that a white woman who crossed the color line risked turning herself “black,” since the “mingling” of her blood with that of her mixed-race child during pregnancy destroyed her “racial purity.” One wonders if Rodman would have required such a woman, then, to identify herself as “black,” or else face accusations that she was ”passing” for white.
