In a taped interview conducted by a blind, black anthropologist, a black man nearly ninety years old said: "Now you must understand that this is just a name we have. I am not black and you are not black either, if you go by the evidence of your eyes.... Anyway, black people are all colors. White people don't look all the same way, but there are more different kinds of us than there are of them. Then too, there is a certain stage [at] which you cannot tell who is white and who is black. Many of the people I see who are thought of as black could just as well be white in their appearance. Many of the white people I see are black as far as I can tell by the way they look. Now, that's it for looks. Looks don't mean much. The things that makes us different is how we think. What we believe is important, the ways we look at life" (Gwaltney, 1980:96).

How does a person get defined as a black, both socially and legally, in the United States? What is the nation's rule for who is black, and how did it come to be? And so what? Don't we all know who is black, and isn't I t the most important issue what opportunities the group has? Let us start with some experiences of three well-known American blacks-actress and beauty pageant winner Vanessa Williams, U.S. Representative Adam Clayton Powell, Jr., and entertainer Lena Horne.

For three decades after the first Miss America Pageant in 1921, black women were barred from competing. The first black winner was Vanessa Williams of Millwood, New York, crowned Miss America 1984. In the same year the first runner-up-Suzette Charles of Mays Landing, New Jersey-was also black. The viewing public was charmed by the television images and magazine pictures of the beautiful and musically talented Williams, but many people were also puzzled. Why was she being called black when she appeared to be white? Suzette Charles, whose ancestry appeared to be more European than African, at least looked like many of the "lighter blacks." Notoriety followed when Vanessa Williams resigned because of the impending publication of some nude photographs of her taken before the pageant, and Suzette Charles became Miss America for the balance of 1984. Beyond the troubling question of whether these young women could have won if they had looked "more black," the publicity dramatized the nation's definition of a black person.

Some blacks complained that the Rev. Adam Clayton Powell, Jr., was so light that be was a stranger in their midst. In the words of Roi Ottley, "He was white to all appearances, having blue eyes, an aquiline nose, and light, almost blond, hair" (1943:220), yet he became a bold, effective black leader-first as minister of the Abyssinian Baptist Church of Harlem, then as a New York city councilman, and finally as a U.S. congressman from the state of New York. Early in his activist career he led 6,000 blacks in a march on New York City Hall. He used his power in Congress to fight for civil rights legislation and other black causes. In 1966, in Washington, D.C., he convened the first black power conference.

In his autobiography, Powell recounts some experiences with racial classification in his youth that left a lasting impression on him. During Powell's freshman year at Colgate University, his roommate did not know that he was a black until his father, Adam Clayton Powell, Sr., was invited to give a chapel talk on Negro rights and problems, after which the roommate announced that because Adam was a Negro they could no longer be roommates or friends.

Another experience that affected Powell deeply occurred one summer during his Colgate years. He was working as a bellhop at a summer resort in Manchester, Vermont, when Abraham Lincoln's aging son Robert was a guest there. Robert Lincoln disliked blacks so much that he refused to let them wait on him or touch his luggage, car, or any of his possessions. Blacks who did got their knuckles whacked with his cane. To the great amusement of the other bellhops, Lincoln took young Powell for a white man and accepted his services (Powell, 1971:31-33).

Lena Horne's parents were both very light in color and came from black upper-middle-class families in Brooklyn (Horne and Schickel, 1965; Buckley, 1986). Lena lived with her father's parents until she was about seven years old. Her grandfather was very light and blue-eyed. Her fair-skinned grandmother was the daughter of a slave woman and her white owner, from the family of John C. Calhoun, well-known defender of slavery. One of her father's great-grandmothers was a Blackfoot Indian, to whom Lena Horne has attributed her somewhat coppery skin color. One of her mother's grandmothers was a French-speaking black woman from Senegal and never a slave. Her mother's father was a "Portuguese Negro," and two women in his family had passed as white and become entertainers.

Lena Horne's parents had separated, and when she was seven her entertainer mother began placing her in a succession of homes in different states. Her favorite place was in the home of her Uncle Frank, her father's brother, a red-haired, blue-eyed teacher in a black. school in Georgia. The black children in that community asked her why she was so light and called her a "yellow bastard." She learned that when satisfactory evidence of respectable black parents is lacking, being light-skinned implies illegitimacy and having an underclass white parent and is thus a disgrace in the black community. When her mother married a white Cuban, Lena also learned that blacks can be very hostile to the white spouse, especially when the "black" mate is very light. At this time she began to blame the confused color line for her childhood troubles. She later endured much hostility from blacks and whites alike when her own second marriage, to white composer-arranger Lennie Hayton, was finally made public in 1950 after three years of keeping it secret.

Early in Lena Horne's career there were complaints that she did not fit the desired image of a black entertainer for white audiences, either physically or in her style. She sang white love songs, not the blues. Noting her brunette-white beauty, one white agent tried to get her to take a Spanish name, learn some Spanish songs, and pass as a Latin white, but she had learned to have a horror of passing and never considered it, although Hollywood blacks accused her of trying to pass after she played her first bit part in a film. After she failed her first screen test because she looked like a white girl trying to play blackface, the directors tried making her up with a shade called "Light Egyptian" to make her look darker. The whole procedure embarrassed and hurt her deeply. Her long struggle to develop a clear sense of self, including a definite racial identity, is explored further in Chapter 7.

Other light mulatto entertainers have also had painful experiences because of their light skin and other Caucasoid features. Starting an acting career is never easy, but actress Jane White's difficulties in the 1940s were compounded by her lightness. Her father was NAACP leader Walter White. Even with dark makeup on her ivory skin, she did not look like a black person on the stage, but she was not allowed to try out for white roles because blacks were barred from playing them. When she auditioned for the part of a young girl from India, the director was enthusiastic, although her skin color was too light, but higher management decreed that it was unthinkable for a Negro to play the part of an Asian Indian (White, 1948:338). Only after great perseverance did Jane White make her debut as the educated mulatto maid Nonnie in the stage version of Lillian Smith's Strange Fruit (1944).

In Southern California in the 1960s, my family and I had a surprising experience with a couple not so well known to the general public as the above three celebrities. We began attending an almost all-white church served by an interim minister who had retired and who was apparently white. Both he and his wife were gentle, intelligent, soft-spoken people who inspired trust. After several weeks, during one of a series of orientation meetings for new members, we were startled to hear our minister call himself black and refer to the black neighborhood in Chicago where he and his family had lived. When we inquired what he meant, he quietly explained that although they did not like to make a fuss about it, he and his wife also did not want to keep their backgrounds a secret and pass as white. When he was recruited, members of the church must have known this, but it was never mentioned. This couple appeared to be white, biologically, yet our minister insisted on their blackness.

THE ONE-DROP RULE DEFINED

As the above cases illustrate, to be considered black in the United States not even half of one's ancestry must be African black. But will one-fourth do, or one-eighth, or less? The nation's answer to the question "Who is black?" has long been that a black is any person with any known African black ancestry (Myrdal, 1944:113-18; Berry and Tischler, 1978:97-98; Williamson, 1980:1-2). This definition reflects the long experience with slavery and later with Jim Crow segregation (see Chapters 3 and 4). In the South it became known as the "one-drop rule," meaning that a single drop of "black blood" makes a person a black. It is also known as the "one black ancestor rule," some courts have called it the "traceable amount rule," and anthropologists call it the "hypo-descent rule," meaning that racially mixed persons are assigned the status of the subordinate group (Harris, 1964:56). This definition emerged from the American South to become the nation's definition, generally accepted by whites and blacks alike (Bahr, Chadwick, and Stauss, 1979:27-28). Blacks had no other choice. As we shall see, this American cultural definition of blacks is taken for granted as readily by judges, affirmative action officers, and black protesters as it is by Ku Klux Klansmen.

Let us not be confused by terminology. At present the usual statement of the one-drop rule is in terms of "black blood" or black ancestry, while not so long ago it referred to "Negro blood" or ancestry. The term "black" rapidly replaced "Negro" in general usage in the United States as the black power movement peaked at the end of the 1960s, but the black and Negro populations are the same. The term "black" is used in this book for persons with any black African lineage, not just for unmixed members of populations from sub-Saharan Africa. The term "Negro," which is used in certain historical contexts, means the same thing. Terms such as "African black," "unmixed Negro," and "all black" are used here to refer to unmixed blacks descended from African populations.

We must also pay attention to the terms "mulatto" and "colored." The term "mulatto" was originally used to mean the offspring of a "pure African Negro" and a "pure white." Although the root meaning of mulatto, in Spanish, is "hybrid , mulatto" came to include the children of unions between whites and so-called "mixed Negroes." For example, Booker T. Washington and Frederick Douglass, with slave mothers and white fathers, were referred to as mulattoes (Bennett, 1962:255). To whatever extent their mothers were part white, these men were more than half white. Douglass was evidently part Indian as well, and he looked it (Preston, 1980:9-10). Washington had reddish hair and gray eyes. At the time of the American Revolution, many of the founding fathers had some very light slaves, including some who appeared to be white. The term "colored" seemed for a time to refer only to mulattoes, especially lighter ones, but later it became a euphemism for darker Negroes, even including unmixed blacks. With widespread racial mixture, "Negro" came to mean any slave or descendant of a slave, no matter how much mixed. Eventually in the United States, the terms mulatto, colored, Negro, black, and African American all came to mean people with any known black African ancestry. Mulattoes are racially mixed, to whatever degree, while the terms black, Negro, African American, and colored include both mulattoes and unmixed blacks. As we shall see, these terms have quite different meanings in other countries.

Whites in the United States need some help envisioning the American black experience with ancestral fractions. At the beginning of miscegenation between two populations presumed to be racially pure, quadroons appear in the second generation of continuing mixing with whites, and octoroons in the third. A quadroon is one-fourth African black and thus easily classed as black in the United States, yet three of this person's four grandparents are white. An octoroon has seven white great-grandparents out of eight and usually looks white or almost so. Most parents of black American children in recent decades have themselves been racially mixed, but often the fractions get complicated because the earlier details of the mixing were obscured generations ago. Like so many white Americans, black people are forced to speculate about some of the fractionsone-eighth this, three-sixteenths that, and so on.

BLACK LEADERS, BUT PREDOMINANTLY WHITE

Many of the nation's black leaders have been of predominantly white ancestry. During slave times, Robert Purvis was the son of a wealthy white Charleston merchant and a free mulatto woman. His father sent him north to be educated at Amherst College and then to live a life of leisure near Philadelphia. He could have passed as white, but instead helped form the American Anti-Slavery Society and became an effective abolitionist leader (Bennett, 1962:252). During the Reconstruction period after the Civil War, all but three of the twenty black congressmen and two black senators in Washington, D.C., were mulattoes, and some were very light. WE. B. Du Bois-sociology professor, critic of Booker T. Washington's view that change toward racial equality had to be gradual, and founder in 1910 of the National Association for the Advancement of Colored People (NAACP)-had French, Dutch, and African ancestors (Bennett, 1962:279).

James Augustine Healy was born in 1830 to a mulatto slave and an Irish planter and taken north to a Quaker school on Long Island in 1837. He graduated from Holy Cross College in 1849, and in 1854 was ordained a priest at Notre Dame Cathedral in Paris, France. He became the first black bishop in the United States, serving in that capacity in Portland, Maine. One of his younger brothers, Patrick Francis Healy, became a Jesuit priest. Later, as Monsignor Healy, Patrick served as president of Georgetown University from 1873 to 1882 and has often been called the second founder" of that institution (Bennett, 1962:253-54).

Walter White, president of the NAACP from 1931 to 1955, was estimated by anthropologists to be no more than one sixty-fourth African black. Both his parents could have passed as white (White, 1948:13; Cannon, 1956:13). When he told whites he was black, they would often say "Are you sure?" They could not understand why a white man wanted to be black (white, 1948:3-4). He had fair skin, fair hair, and blue eyes, yet he chose not to pass as white. He had been raised as a segregated Negro in the Deep South and had experienced white discrimination and violence. Ottley characterized Walter White as "one of the shrewdest negotiators of the race" (1943:244). The "race" for which White negotiated was the ethnic group with which he identified his community certainly not his correct genetic classification.

In a biography of Walter White, his second wife, a brunette white, reveals their experiences as an "interracial couple" (Cannon, 1956:14). When they toured the world with an American goodwill mission and were referred to as an interracial couple, puzzled people often asked White how he happened to marry a "colored" woman. The black press was outraged by this marriage (Cannon, 1956:12-13), as it had been decades earlier by the marriage of Frederick Douglass to a white and by the second marriage of Lena Horne. Although the genetic crossing in White's marriage was minute at most, he had married across the social group barrier, outside the black community.

Another major black leader of the twentieth century, A. Philip Randolph, was predominantly white. His mother and his mother's father both could pass as white (Anderson, 1972:31). As a boy, Randolph shared his minister father's outrage when the Jim Crow laws were passed in Jacksonville, Florida, depriving blacks of political participation and segregating the library, streetcars, and other public facilities. In New York, Randolph became a leading black editor and head of the small but influential Brotherhood of Sleeping Car Porters. He was chiefly responsible for pressuring President Franklin Roosevelt into signing the World War 11 order against racial segregation in war industries and for getting President Harry Truman to sign the order in 1948 to desegregate the U. S. armed forces. He also organized marches on Washington, D.C., including the gigantic rally in 1963 at which the Rev. Dr. Martin Luther King, Jr., gave his "I have a dream" speech. We may note also that King had an Irish grandmother on his father's side and apparently some American Indian ancestry (Bennett, 1965:18).

PLESSY,, PHIPPS, AND OTHER CHALLENGES IN THE COURTS

Homer Plessy was the plaintiff in the 1896 precedent-setting "separate-but-equal" case of Plessy v. Ferguson (163 U.S. 537). This case challenged the Jim Crow statute that required racially segregated seating on trains in interstate commerce in the state of Louisiana. The U.S. Supreme Court quickly dispensed with Plessy's contention that because he was only one-eighth Negro and could pass as white he was entitled to ride in the seats reserved for whites. Without ruling directly on the definition of a Negro, the Supreme Court briefly took what is called "Judicial notice" of what it assumed to be common knowledge: that a Negro or black is any person with any black ancestry. (judges often take explicit "judicial notice" not only of scientific or scholarly conclusions, or of opinion surveys or other systematic investigations, but also of something they just assume to be so, including customary practices or common knowledge.) This has consistently been the ruling in the federal courts, and often when the black ancestry was even less than one-eighth. The federal courts have thus taken judicial notice of the customary boundary between two sociocultural groups that differ, on the average, in physical traits, not between two discrete genetic categories. In the absence of proof of a specific black ancestor, merely being known as a black in the community has usually been accepted by the courts as evidence of black ancestry. The separatebut-equal doctrine established in the Plessy case is no longer the law, as a result of the judicial and legislative successes of the civil rights movement, but the nation's legal definition of who is black remains unchanged.

State courts have generally upheld the one-drop rule. For instance, in a 1948 Mississippi case a young man, Davis Knight, was sentenced to five years in jail for violating the anti-miscegenation statute. Less than one-sixteenth black, Knight said he was not aware that he had any black lineage, but the state proved his great-grandmother was a slave girl. In some states the operating definition of black has been limited by statute to particular fractions, yet the social definition-the one-drop rule-has generally prevailed in case of doubt. Mississippi, Missouri, and five other states have had the criterion of one-eighth. Virginia changed from one-fourth to one-eighth in 1910, then in 1930 forbade white intermarriage with a person with any black ancestry. Persons in Virginia who are one-fourth or more Indian and less than one-sixteenth African black are defined as Indians while on the reservation but as blacks when they leave (Berry, 1965:26). While some states have had general race classification statutes, at least for a time, others have legislated a definition of black only for particular purposes, such as marriage or education. In a few states there have even been varying definitions for different situations (Mangum, 1940:38-48). All states require a designation of race on birth certificates, but there are no clear guidelines to help physicians and midwives do the classifying.

Louisiana's latest race classification statute became highly controversial and was finally repealed in 1983 (Trillin, 1986:77). Until 1970, a Louisiana statute had embraced the one-drop rule, defining a Negro as anyone with a "trace of black ancestry." This law was challenged in court a number of times from the 1920s on, including an unsuccessful attempt in 1957 by boxer Ralph Dupas, who asked to be declared white so that a law banning "interracial sports" (since repealed) would not prevent him from boxing in the state. In 1970 a lawsuit was brought on behalf of a child whose ancestry was allegedly only one two-hundred-fifty-sixth black, and the legislature revised its law. The 1970 Louisiana statute defined a black as someone whose ancestry is more than one thirty-second black (La. Rev. Stat. 42:267). Adverse publicity about this law was widely disseminated during the Phipps trial in 1983 (discussed below), filed as Jane Doe v. State of Louisiana. This case was decided in a district court in May 1983, and in June the legislature abolished its one thirty-second statute and gave parents the right to designate the race of newborns, and even to change classifications on birth certificates if they can prove the child is white by a "preponderance of the evidence." However, the new statute in 1983 did not abolish the "traceable amount rule" (the one-drop rule), as demonstrated by the outcomes when the Phipps decision was appealed to higher courts in 1985 and 1986.

The history in the Phipps (Jane Doe) case goes as far back as 1770, when a French planter named jean Gregoire Guillory took his wife's slave, Margarita, as his mistress (Model, 1983:3-4). More than two centuries and two decades later, their great-great-great-great-granddaughter, Susie Guillory Phipps, asked the Louisiana courts to change the classification on her deceased parents' birth certificates to "white" so she and her brothers and sisters could be designated white. They all looked white, and some were blue-eyed blonds. Mrs. Susie Phipps had been denied a passport because she had checked "white" on her application although her birth certificate designated her race as "colored." This designation was based on information supplied by a midwife, who presumably relied on the parents or on the family's status in the community. Mrs. Phipps claimed that this classification came as a shock, since she had always thought she was white, had lived as white, and had twice married as white. Some of her relatives, however, gave depositions saying they considered themselves "colored," and the lawyers for the state claimed to have proof that Mrs. Phipps is three-thirty-seconds black (Trillin, 1986:62-63, 71-74). That was more than enough "blackness" for the district court in 1983 to declare her parents, and thus Mrs. Phipps and her siblings, to be legally black.

In October and again in December 1985, the state's Fourth Circuit Court of Appeals upheld the district court's decision, saying that no one can change the racial designation of his or her parents or anyone else's (479 So. 2d 369). Said the majority of the court in its opinion: "That appellants might today describe themselves as white does not prove error in a document which designates their parents as colored" (479 So. 2d 371). Of course, if the parents' designation as "colored" cannot be disturbed, their descendants must be defined as black by the "traceable amount rule." The court also concluded that the preponderance of the evidence clearly showed that the Guillory parents were "colored." Although noting expert testimony to the effect that the race of an individual cannot be determined with scientific accuracy, the court said the law of racial designation is not based on science, that "individual race designations are purely social and cultural perceptions and the evidence conclusively proves those subjective perspectives were correctly recorded at the time the appellants' birth certificates were recorded" (479 So. 2d 372). At the rehearing in December 1985, the appellate court also affirmed the necessity of designating race on birth certificates for public health, affirmative action, and other important public programs and held that equal protection of the law has not been denied so long as the designation is treated as confidential.

When this case was appealed to the Louisiana Supreme Court in 1986, that court declined to review the decision, saying only that the court 'concurs in the denial for the reasons assigned by the court of appeals on rehearing" (485 So. 2d 60). In December 1986 the U.S. Supreme-Court was equally brief in stating its reason for refusing to review the decision: "The appeal is dismissed for want of a substantial federal question" (107 Sup. Ct. Reporter, interim ed. 638). Thus, both the final court of appeals in Louisiana and the highest court of the United States saw no reason to disturb the application of the one-drop rule in the lawsuit brought by Susie Guillory Phipps and her siblings.

CENSUS ENUMERATION OF BLACKS

When the U.S. Bureau of the Census enumerates blacks (always counted as Negroes until 1980), it does not use a scientific definition, but rather the one accepted by the general public and by the courts. The Census Bureau counts what the nation wants counted. Although various operational instructions have been tried, the definition of black used by the Census Bureau has been the nation's cultural and legal definition: all persons with any known black ancestry. Other nations define and count blacks differently, so international comparisons of census data on blacks can be extremely misleading. For example', Latin American countries generally count as black only unmixed African blacks, those onlv slightly mixed, and the very poorest mulattoes (see Chapter 5). If they used the U.S. definition, they would count far more blacks than they do, and if Americans used their definition, millions in the black community in the United States would be counted either as white or as "coloreds" of different descriptions, not as black.

Instructions to our census enumerators in 1840, 1850, and 1860 provided "mulatto" as a category but did not define the term. In 1870 and 1880, mulattoes were officially defined to include "quadroons, octoroons, and all persons having any perceptible trace of African blood." In 1890 enumerators were told to record the exact proportion of the "African blood," again relying on visibility. In 1900 the Census Bureau specified that "pure Negroes" be counted separately from mulattoes, the latter to mean "all persons with some trace of black blood." In 1920 the mulatto category was dropped, and black was defined to mean any person with any black ancestry, as it has been ever since.

In 1960 the practice of self-definition began, with the head of household indicating the race of its members. This did not seem to introduce any noticeable fluctuation in the number of blacks, thus indicating that black Americans generally apply the one-drop rule to themselves. One exception is that Spanish-speaking Americans who have black ancestry but were considered white, or some designation other than black, in their place of origin generally reject the one-drop rule if they can. American Indians with some black ancestry also generally try to avoid the rule, but those who leave the reservation are often treated as black. At any rate, the 1980 census count showed that self-designated blacks made up about 12 percent of the population of the United States.

No other ethnic population in the nation, including those with visibly non-caucasoid features, is defined and counted according to a one-drop rule. For example, persons whose ancestry is one-fourth or less American Indian are not generally defined as Indian unless they want to be, and they are considered assimilating Americans who may even be proud of having some Indian ancestry. The same implicit rule appears to apply to Japanese Americans, Filipinos, or other peoples from East Asian nations and also to Mexican Americans who have Central American Indian ancestry, as a large majority do. For instance, a person whose ancestry is one-eighth Chinese is not defined as just Chinese, or East Asian, or a member of the mongoloid race. The United States certainly does not apply a one-drop rule to its white ethnic populations either, which include both national and religious groups. Ethnicity has often been confused with racial biology (see Chapter 2), and not just in Nazi Germany. Americans do not insist that an American with a small fraction of Polish ancestry be classified as a Pole, or that someone with a single remote Greek ancestor be designated Greek, or that someone with any trace of Jewish lineage is a Jew and nothing else.

It is interesting that, in The Passing of the Great Race (1916), Madison Grant maintained that the one-drop rule should be applied not only to blacks but also to all the other ethnic groups he considered biologically inferior "races," such as Hindus, Asians in general, Jews, Italians, and other Southern and Eastern European peoples. Grant's book went through four editions, and he and others succeeded in getting Congress to pass the national origins quota laws of the early 1920s. This racist quota legislation sharply curtailed immigration from everywhere in the world except Northern and Western Europe and the Western Hemisphere, until it was repealed in 1965. Grant and other believers in the racial superiority of their own group have confused race with ethnicity. They consider miscegenation with any "inferior" people to be the ultimate danger to the survival of their own group and have often seen the one-drop rule as a crucial component in their line of defense. Americans in general, however, while finding other ways to discriminate against immigrant groups, have rejected the application of the drastic one-drop rule to all groups but blacks.

UNIQUENESS OF THE ONE-DROP RULE

Not only does the one-drop rule apply to no other group than American blacks, but apparently the rule is unique in that it is found only in the United States and not in any other nation in the world. In fact, definitions of who is black vary quite sharply from country to country (see Chapter 5), and for this reason people in other countries often express consternation about our definition. James Baldwin relates a revealing incident that occurred in 1956 at the Conference of Negro-African Writers and Artists held in Paris. The head of the delegation of writers and artists from the United States was John Davis. The French chairperson introduced Davis and then asked him why he considered himself Negro, since he certainly did not look like one. Baldwin wrote, "He is a Negro, of course, from the remarkable legal point of view which obtains in the United States, but more importantly, as he tried to make clear to his interlocutor, he was a Negro by choice and by depth of involvement-by experience, in fact" (1962:19).

The phenomenon known as 11 passing as white" is difficult to explain in other countries or to foreign students. Typical questions are: "Shouldn't Americans say that a person who is passing as white is white, or nearly all white, and has previously been passing as black?" or "To be consistent, shouldn't you say that someone who is one-eighth white is passing as black?" or "Why is there so much concern, since the so-called blacks who pass take so little negroid ancestry with them?" Those who ask such questions need to realize that "passing" is much more a social phenomenon than a biological one, reflecting the nation's unique definition of what makes a person black. The concept of "passing" rests on the onedrop rule and on folk beliefs about race and miscegenation, not on biological or historical fact.

The black experience with passing as white in the United States contrasts with the experience of other ethnic minorities that have features that are clearly non-caucasoid. The concept of passing applies only to blacks-consistent with the nation's unique definition of the group. A person who is one-fourth or less American Indian or Korean or Filipino is not regarded as passing if he or she intermarries and joins fully the life of the dominant community, so the minority ancestry need not be hidden. It is often suggested that the key reason for this is that the physical differences between these other groups and whites are less pronounced than the physical differences between African blacks and whites, and therefore are less threatening to whites. However, keep in mind that the one-drop rule and anxiety about passing originated during slavery and later received powerful reinforcement under the Jim Crow system.

For the physically visible groups other than blacks, miscegenation promotes assimilation, despite barriers of prejudice and discrimination during two or more generations of racial mixing. As noted above, when ancestry in one of these racial minority groups does not exceed onefourth, a person is not defined solely as a member of that group. Masses of white European immigrants have climbed the class ladder not only through education but also with the help of close personal relationships in the dominant community, intermarriage, and ultimately full cultural and social assimilation. Young people tend to marry people they meet in the same informal social circles (Gordon, 1964:70-81). For visibly noncaucasoid minorities other than blacks in the United States, this entire route to full assimilation is slow but possible.

For all persons of any known black lineage, however, assimilation is blocked and is not promoted by miscegenation. Barriers to full opportunity and participation for blacks are still formidable, and a fractionally black person cannot escape these obstacles without passing as white and cutting off all ties to the black family and community. The pain of this separation, and condemnation by the black family and community, are major reasons why many or most of those who could pass as white choose not to. Loss of security within the minority community, and fear and distrust of the white world are also factors.

It should now be apparent that the definition of a black person as one with any trace at all of black African ancestry is inextricably woven into the history of the United States. It incorporates beliefs once used to justify slavery and later used to buttress the castelike Jim Crow system of segregation. Developed in the South, the definition of "Negro" (now black) spread and became the nation's social and legal definition (see Chapter 3). Because blacks are defined according to the one-drop rule, they are a socially constructed category in which there is wide variation in racial traits and therefore not a race group in the scientific sense (see Chapter 2). However, because that category has a definite status position in the society it has become a self-conscious social group with an ethnic identity.

The one-drop rule has long been taken for granted throughout the United States by whites and blacks alike, and the federal courts have taken "judicial notice" of it as being a matter of common knowledge.

State courts have generally upheld the one-drop rule, but some have limited the definition to one thirty-second or one-sixteenth or one-eighth black ancestry, or made other limited exceptions for persons with both Indian and black ancestry. Most Americans seem unaware that this definition of blacks is extremely unusual in other countries, perhaps even unique to the United States, and that Americans define no other minority group in a similar way.

In the United States there are still complex, major issues about the opportunities and rights of blacks, but none concerning how we define who is black. The personnel officer, the census taker, the judge, the school admissions staff, the affirmative action officer, and the black political caucus leader all readily classify a predominantly white mulatto as a black person. Spanish-speaking people are often exempted if they are not too dark, and other deviations from the rule are noted in Chapter 6, yet the one-drop rule has generally prevailed. Even so, the rule has its costs, and the attendant ambiguities, strains, conflicts, and traumatic experiences are explored in Chapter 7.

The aim here is to contribute to a greater understanding of the origins, operation, and effects of the American definition of who is black and thus to fuller knowledge about race relations in the United States. To accomplish this, we examine the unique history of black-white relations in American society and observe contrasts with the corresponding rules and experiences in other societies with racially mixed populations. Arbitrary and contradictory as our one-drop rule is, it is deeply embedded in the social structures and cultures of both the black and the white communities in the United States and strongly resistant to change. The final chapter raises basic questions about prospects for the future.

The analysis in this book, although it is based on materials pertinent to a number of theoretical perspectives, has been oriented primarily toward an approach that emphasizes conflict and differences in group power (Davis, 1978:27-31). Latent conflict is common in patterns of accommodation between racial or ethnic groups, because typically these patterns reflect inequalities of group power and include institutionalized discrimination (Blalock, 1967:139; Blackwell, 1975:29-32). When conflicts become overt, they may under the right conditions effect changes in relative power and in patterns of intergroup relations. Only after cataclysmic struggles will dominant groups let go of such extremely unequal and highly institutionalized systems as slavery, Jim Crow segregation, or Apartheid. Rules for intergroup relations, including social definitions of racial categories, are forged and changed in power politics. Both customary and legal classifications of racial and ethnic groups are products of complex cross-pressures brought to bear by interest groups that have different amounts of power (Dominguez, 1986:12, 23-55, 267-73). We now turn to the development of the one-drop rule through the conflicts and changing patterns of black-white relations in the United States.
