In the 18th and 19th century, racialist written works proposed geographically based "scientific" differences among "the races." Many of these racial models assigned colors to the groups described, and some included a "brown race" as in the following:
Jean Baptiste Julien d'Omalius d'Halloy's five-race scheme differed from Blumenbach's by including Ethiopians in the brown race, as well as Oceanic peoples. Louis Figuier adopted and adapted d'Omalius d'Halloy's classification and also included Egyptians in the brown race.
In 1915, Donald Mackenzie conceived a "Mediterranean or Brown race, the eastern branch of which reaches to India and the western to the British Isles... predynastic Egyptians... Neolithic man".
Due to what he considered the relatively close physical relationship between many populations "from the Red Sea as far as India, including Semites as well as Hamites", Grafton Elliot Smith conceived the Brown Race as a natural extension of Giuseppe Sergi's earlier Mediterranean race concept. In this popular conception, the Brown Race consisted of a joint "Mediterranean-Hamite-Semite" grouping of ancestrally related peoples, into which Elliot Smith included the Proto-Egyptians.
These and other racialist theories have been dismissed scientifically. As a 2012 human biology textbook observes, "These claims of race-based taxonomy, including Coon's claims for homo-sapienation, have been discredited by paleontological and genomic research showing the antiquity of modern human origins, as well as the essential genomic African nature of all living human beings."
Subdivisions
In the 19th century, the notion of a single "brown people" was sometimes superseded by multiple "brown peoples." Cust mentions Grammar in 1852 denying that there was one single "brown race", but in fact several races speaking distinct languages. The 1858 Cyclopaedia of India and of eastern and southern Asia notes that Keane was dividing the "brown people" into quaternion: a western branch that he termed the Malay, a north-western group that he termed the Micronesian, and the peoples of the eastern archipelagos that he termed the Maori and the Polynesian.
Ethnic and racial identifier
The appellation "brown people" has been applied in the 20th and 21st centuries to several groups. Edward Telles, a sociologist of race and ethnicity, and Jack Forbes both argue that this classification is biologically invalid. However, as Telles notes, it is still of sociological significance. Irrespective of the actual biological differences amongst humans, and of the actual complexities of human skin coloration, people nonetheless self-identify as "brown" and identify other groups of people as "brown", using characteristics that include skin color, hair strength, language, and culture, in order to classify them. Forbes remarks upon a process of "lumping", whereby characteristics other than skin color, such as hair color or curliness, act as "triggers" for color categories "even when it may not be appropriate."
In 1950s South Africa the "brown people" were the Coloureds, referring to those born of multiracial sexual unions out of wedlock. They were distinct from the Reheboth Basters inhabiting Namibia, who were primarily of Khoisan and European parentage. The Afrikaans terms, which incorporate many subtleties of heritage, political agenda, and identity, are "", "", and "". Some South Africans prefer the appellation "bruinmense" to "Colored". The South Africanpencil test was one example of a characteristic other than skin color being used as a determiner. The pencil test, which distinguished either "black" from "Colored" or "Colored" from "white", relied upon curliness and strength of hair rather than upon any color factor at all. The pencil test could "trump skin color". Steve Biko, in his trial in 1976, rejected the appellation "brown people" when it was put to him incorrectly by Judge Boshoff: Penelope Oakes characterizes Biko's argument as picking "black" over "brown" because for Biko it is "the most valid, meaningful and appropriate representation, even though in an individualistic decontextualized sense it might appear wrong". This contrasts with Piet Uithalder, fictional protagonist of the satirical column "Straatpraatjes" that appeared in the Dutch-Afrikaans section of the newspaper APO between May 1909 and February 1922. Uithalder would self-identify as a Colored person, with the column targeted at a Colored readership, introducing himself as "een van de ras" and characterizing himself as a "bruine mens".
Pardos in Brazil
In popular use, Brazilians also use a category of ' m., ' f., lit. , from , Portuguese for 'Moor', which were perceived as people with darker phenotypes than Indigenous Europeans, so a moreno or morena is a person with a "Moorish" phenotype), which is extremely ambiguous, as it can mean "dark-haired people", but is also used as a euphemism for pardo, and even "Black". In a 1995 survey, 32% of the population self-identified as moreno, with a further 6% self-identifying as moreno claro''. 7% self-identified as "pardo". A comprehensive study presented by the Brazilian Journal of Medical and Biological Research found that on average, 'white' Brazilians have >50% European genomic ancestry, whereas 'black' Brazilians have 17.1% European genomic ancestry. It concluded that "The high ancestral variability observed in Whites and Blacks suggests that each Brazilian has a singular and quite individual proportion of European, African and Amerindian ancestry in his/her mosaic genomes. Thus, the only possible basis to deal with genetic variation in Brazilians is not by considering them as members of color groups, but on a person-by-person basis, as 190 million human beings, with singular genome and life histories".
Use in Canada
Relating to brown identity, the popular usage of the term in Canada refers to individuals of South Asian ancestry.
"Brown" has been used as a term in popular culture for some South Asian Americans, Hispanic and LusoLatinos either as a pejorative term or sometimes for self-identification, as with brown identity. Judith Ortiz Cofer notes that appellation varies according to geographical location, observing that in Puerto Rico she is considered to be a white person, but in the United States mainland, she is considered to be a "brown person." Moustafa Bayoumi, a professor of English at Brooklyn College, identified himself as a brown Arab-American in an opinion piece criticizing the United States Census for forcing self-identified brown persons to identify as white. The term "Brown American" has been used both as a term of insult and as self-identification in referring to Filipino Americans.
