Black is a racial classification of people, usually a political and skin color-based category for specific populations with a mid- to dark brown complexion. Often in countries with socially based systems of racial classification in the Western world, the term "black" is used to describe persons who are perceived as darker-skinned in contrast to other populations. It is most commonly used for people of African ancestry, Indigenous Australians, Melanesians, and Negritos, though it has been applied in many contexts to other groups, and is no indicator of any close ancestral relationship whatsoever. However, not all people considered "black" have dark skin and often additional phenotypical characteristics are relevant, such as certain facial and hair-texture features. Indigenous African societies do not use the term black as a racial identity outside of influences brought by Western cultures.
Contemporary anthropologists and other scientists, while recognizing the reality of biological variation between different human populations, regard the concept of a "Black race" as social construct. Different societies apply different criteria regarding who is classified "black", and these social constructs have changed over time. In a number of countries, societal variables affect classification as much as skin color, and the social criteria for "blackness" vary. Some perceive the term 'black' as a derogatory, outdated, reductive or otherwise unrepresentative label, and as a result neither use nor define it, especially in African countries with little to no history of colonial racial segregation.
In the anglosphere, the term can carry a variety of meanings depending on the country. While the term "person of color" is commonly used and accepted in the United States, the near-sounding term "colored person" is considered highly offensive, except in South Africa, where Coloureds are a specific multiracial group. In other regions such as Australia and Melanesia, settlers applied the adjective "black" to the indigenous population. It was universally regarded as highly offensive in Australia until the 1960s and 1970s. "Black" was generally not used as a noun, but rather as an adjective qualifying some other descriptor. As desegregation progressed after the 1967 referendum, some Indigenous Australians adopted the term, following the American fashion, but it remains problematic.

Several American style guides, including the AP Stylebook, changed their guides to capitalize the 'b' in 'black', following the 2020 murder of George Floyd, an African American. The ASA Style Guide says that the 'b' should not be capitalized.
Africa
Northern Africa
Numerous communities of dark-skinned peoples are present in North Africa, some dating from prehistoric communities. Others descend from migrants via the historical trans-Saharan trade or, after the Arab invasions of North Africa in the 7th century, from slaves from the trans-Saharan slave trade in North Africa.
In the 18th century, the Moroccan Sultan Moulay Ismail "the Warrior King" (1672–1727) raised a corps of 150,000 black soldiers, called his Black Guard.

Notable Islamic caliphs with African ancestry include Abu al-Misk Kafur Al-Mustansir Billah, Yaqub al-Mansur, Abu al-Hasan Ali ibn Othman, Sultan of the Marinid dynasty and Moulay Ismail Ibn Sharif.
According to Carlos Moore, resident scholar at Brazil's University of the State of Bahia, in the 21st century Afro-multiracials in the Arab world, including Arabs in North Africa, self-identify in ways that resemble multi-racials in Latin America. He claims that darker-toned Arabs, much like darker-toned Latin Americans, consider themselves white because they have some distant white ancestry.
Egyptian president Anwar Sadat had a mother who was a dark-skinned Nubian Sudanese (Sudanese Arab) woman and a father who was a lighter-skinned Egyptian. In response to an advertisement for an acting position, as a young man he said, "I am not white but I am not exactly black either. My blackness is tending to reddish".

Due to the patriarchal nature of Arab society, Arab men, including during the slave trade in North Africa, enslaved more African women than men. The female slaves were often put to work in domestic service and agriculture. The men interpreted the Quran to permit sexual relations between a male master and his enslaved females outside of marriage (see Ma malakat aymanukum and sex), leading to many mixed-race children. When an enslaved woman became pregnant with her Arab master's child, she was considered as umm walad or "mother of a child", a status that granted her privileged rights. The child was given rights of inheritance to the father's property, so mixed-race children could share in any wealth of the father. Because the society was patrilineal, the children inherited their fathers' social status at birth and were born free.
Some mixed-race children succeeded their respective fathers as rulers, such as Sultan Ahmad al-Mansur, who ruled Morocco from 1578 to 1608. He was not technically considered as a mixed-race child of a slave; his mother was Fulani and a concubine of his father.
In early 1991, non-Arabs of the Zaghawa people of Sudan attested that they were victims of an intensifying Arab apartheid campaign, segregating Arabs and non-Arabs (specifically, people of Nilotic ancestry). Sudanese Arabs, who controlled the government, were widely referred to as practicing apartheid against Sudan's non-Arab citizens. The government was accused of "deftly manipulating Arab solidarity" to carry out policies of apartheid and ethnic cleansing.
Sudanese Arabs are also black people in that they are culturally and linguistically Arabized indigenous peoples of Sudan of mostly Nilo-Saharan, Nubian, and Cushitic ancestry; their skin tone and appearance resembles that of other black people.
American University economist George Ayittey accused the Arab government of Sudan of practicing acts of racism against black citizens. According to Ayittey, "In Sudan... the Arabs monopolized power and excluded blacks – Arab apartheid." Many African commentators joined Ayittey in accusing Sudan of practicing Arab apartheid.
Sahara
The Tuareg people have in the past had a highly socially stratified society, with specific social roles (warriors, religious leaders) or professions (blacksmiths, farmers, merchants) assigned to specific castes. The tiny aristocratic caste of warrior elite which once sat atop a pyramid of Tuareg society was decimated during the wars of the colonial period, and this, along with economic necessity, post-colonial border restrictions, and modern education, have broken down many traditional caste barriers.

Tuareg higher caste traditions value a nomadic life, warfare, study, animal husbandry, and trade. Consequently, higher caste communities travel, at least seasonally, if able. Lower caste groups, not limited to the Ikelan, are more likely to live in settled communities, either in Sahara oasis towns or in villages scattered among other ethnic groups in the Sahel region to the south.
Horn of Africa
In Ethiopia and Somalia, the slave classes mainly consisted of captured peoples from the Sudanese-Ethiopian and Kenyan-Somali international borders or other surrounding areas of Nilotic and Bantu peoples who were collectively known as Shanqella and Adone (both analogues to "negro" in an English-speaking context). Some of these slaves were captured during territorial conflicts in the Horn of Africa and then sold off to slave merchants. The earliest representation of this tradition dates from a seventh or eighth century BC inscription belonging to the Kingdom of Damat.
These captives and others of analogous morphology were distinguished as tsalim barya (dark-skinned slave) in contrast with the Afroasiatic-speaking nobles or saba qayh ("red men") or light-skinned slave; while on the other hand, western racial category standards do not differentiate between saba qayh ("red men"—light-skinned) or saba tiqur ("black men"—dark-skinned) Horn Africans (of either Afroasiatic-speaking, Nilotic-speaking or Bantu origin) thus considering all of them as "black people" (and in some case "negro") according to Western society's notion of race.

Southern Africa
In South Africa, the period of colonisation resulted in many unions and marriages between European and Africans (Bantu peoples of South Africa and Khoisans) from various tribes, resulting in mixed-race children. As the European colonialists acquired control of territory, they generally pushed the mixed-race and African populations into second-class status. During the first half of the 20th century, the white-dominated government classified the population according to four main racial groups: Black, White, Asian (mostly Indian), and Coloured. The Coloured group included people of mixed Bantu, Khoisan, and European ancestry (with some Malay ancestry, especially in the Western Cape). The Coloured definition occupied an intermediary political position between the Black and White definitions in South Africa. It imposed a system of legal racial segregation, a complex of laws known as apartheid.
The apartheid bureaucracy devised complex (and often arbitrary) criteria in the Population Registration Act of 1945 to determine who belonged in which group. Minor officials administered tests to enforce the classifications. When it was unclear from a person's physical appearance whether the individual should be considered Coloured or Black, the "pencil test" was used. A pencil was inserted into a person's hair to determine if the hair was kinky enough to hold the pencil, rather than having it pass through, as it would with smoother hair. If so, the person was classified as Black. Such classifications sometimes divided families.
Sandra Laing is a South African woman who was classified as Coloured by authorities during the apartheid era, due to her skin colour and hair texture, although her parents could prove at least three generations of European ancestors. At age 10, she was expelled from her all-white school. The officials' decisions based on her anomalous appearance disrupted her family and adult life. She was the subject of the 2008 biographical dramatic film Skin, which won numerous awards. During the apartheid era, those classed as "Coloured" were oppressed and discriminated against. But, they had limited rights and overall had slightly better socioeconomic conditions than those classed as "Black". The government required that Blacks and Coloureds live in areas separate from Whites, creating large townships located away from the cities as areas for Blacks.
In the post-apartheid era, the Constitution of South Africa has declared the country to be a "Non-racial democracy". In an effort to redress past injustices, the ANC government has introduced laws in support of affirmative action policies for Blacks; under these they define "Black" people to include "Africans", "Coloureds" and "Asians". Some affirmative action policies favor "Africans" over "Coloureds" in terms of qualifying for certain benefits. Some South Africans categorized as "African Black" say that "Coloureds" did not suffer as much as they did during apartheid. "Coloured" South Africans are known to discuss their dilemma by saying, "we were not white enough under apartheid, and we are not black enough under the ANC (African National Congress)".
In 2008, the High Court in South Africa ruled that Chinese South Africans who were residents during the apartheid era (and their descendants) are to be reclassified as "Black people", solely for the purposes of accessing affirmative action benefits, because they were also "disadvantaged" by racial discrimination. Chinese people who arrived in the country after the end of apartheid do not qualify for such benefits.
Other than by appearance, "Coloureds" can usually be distinguished from "Blacks" by language. Most speak Afrikaans or English as a first language, as opposed to Bantu languages such as Zulu or Xhosa. They also tend to have more European-sounding names than Bantu names.
Asia
Afro-Asians
"Afro-Asians" or "African-Asians" are persons of mixed African and Asian ancestry. In the United States, they are also called "black Asians" or "Blasians". Historically, Afro-Asian populations have been marginalized as a result of human migration and social conflict.
Western Asia
Arab world
In the medieval Arab world, the ethnic designation of "Black" encompassed not only Zanj, or Africans, but also communities like Zutt, Sindis and Indians from the Indian subcontinent. Historians estimate that between the advent of Islam in 650 CE and the abolition of slavery in the Arabian Peninsula in the mid-20th century, 10 to 18 million black Africans (known as the Zanj) were enslaved by east African slave traders and transported to the Arabian Peninsula and neighboring countries. This number far exceeded the number of slaves who were taken to the Americas. Slavery in Saudi Arabia and slavery in Yemen was abolished in 1962, slavery in Dubai in 1963, and slavery in Oman in 1970.
Several factors affected the visibility of descendants of this diaspora in 21st-century Arab societies: The traders shipped more female slaves than males, as there was a demand for them to serve as concubines in harems in the Arabian Peninsula and neighboring countries. Male slaves were castrated in order to serve as harem guards. The death toll of black African slaves from forced labor was high. The mixed-race children of female slaves and Arab owners were assimilated into the Arab owners' families under the patrilineal kinship system. As a result, few distinctive Afro-Arab communities have survived in the Arabian Peninsula and neighboring countries.
Distinctive and self-identified black communities have been reported in countries such as Iraq, with a reported 1.2 million black people (Afro-Iraqis), and they attest to a history of discrimination. These descendants of the Zanj have sought minority status from the government, which would reserve some seats in Parliament for representatives of their population. According to Alamin M. Mazrui et al., generally in the Arabian Peninsula and neighboring countries, most of these communities identify as both black and Arab.
Iran
Afro-Iranians are people of black African ancestry residing in Iran. During the Qajar dynasty, many wealthy households imported black African women and children as slaves to perform domestic work. This slave labor was drawn exclusively from the Zanj, who were Bantu-speaking peoples that lived along the African Great Lakes, in an area roughly comprising modern-day Tanzania, Mozambique and Malawi.
Israel
About 150,000 East African and black people live in Israel, amounting to just over 2% of the nation's population. The vast majority of these, some 120,000, are Beta Israel, most of whom are recent immigrants who came during the 1980s and 1990s from Ethiopia. In addition, Israel is home to more than 5,000 members of the African Hebrew Israelites of Jerusalem movement that are ancestry of African Americans who emigrated to Israel in the 20th century, and who reside mainly in a distinct neighborhood in the Negev town of Dimona. Unknown numbers of black converts to Judaism reside in Israel, most of them converts from the United Kingdom, Canada, and the United States.
Additionally, there are around 60,000 non-Jewish African immigrants in Israel, some of whom have sought asylum. Most of the migrants are from communities in Sudan and Eritrea, particularly the Niger-Congo-speaking Nuba groups of the southern Nuba Mountains; some are illegal immigrants.
Turkey
Beginning several centuries ago, during the period of the Ottoman Empire, tens of thousands of Zanj captives were brought by slave traders to plantations and agricultural areas situated between Antalya and Istanbul, which gave rise to the Afro-Turk population in present-day Turkey. Some of their ancestry remained in situ, and many migrated to larger cities and towns. Other black slaves were transported to Crete, from where they or their descendants later reached the İzmir area through the population exchange between Greece and Turkey in 1923, or indirectly from Ayvalık in pursuit of work.
Apart from the historical Afro-Turk presence Turkey also hosts a sizeable immigrant black population since the end of the 1990s. The community is composed mostly of modern immigrants from Ghana, Ethiopia, DRC, Sudan, Nigeria, Kenya, Eritrea, Somalia and Senegal. According to official figures 1.5 million Africans live in Turkey and around 25% of them are located in Istanbul. Other studies state the majority of Africans in Turkey lives in Istanbul and report Tarlabaşı, Dolapdere, Kumkapı, Yenikapı and Kurtuluş as having a strong African presence.
Most of the African immigrants in Turkey come to Turkey to further migrate to Europe. Immigrants from Eastern Africa are usually refugees, meanwhile Western and Central African immigration is reported to be economically driven. It is reported that African immigrants in Turkey regularly face economic and social challenges, notably racism and opposition to immigration by locals.
Southern Asia
The Siddi are an ethnic group inhabiting India and Pakistan. Members are descended from the Bantu peoples of Southeast Africa. Some were merchants, sailors, indentured servants, slaves or mercenaries. The Siddi population is currently estimated at 270,000–350,000 individuals, living mostly in Karnataka, Gujarat, and Hyderabad in India and Makran and Karachi in Pakistan. In the Makran strip of the Sindh and Balochistan provinces in southwestern Pakistan, these Bantu descendants are known as the Makrani. There was a brief "Black Power" movement in Sindh in the 1960s and many Siddi are proud of and celebrate their African ancestry.
Southeastern Asia
Negritos, are a collection of various, often unrelated peoples, who were once considered a single distinct population of closely related groups, but genetic studies showed that they descended from the same ancient East Eurasian meta-population which gave rise to modern East Asian peoples, and consist of several separate groups, as well as displaying genetic heterogeneity. They inhabit isolated parts of Southeast Asia, and are now confined primarily to Southern Thailand, the Malay Peninsula, and the Andaman Islands of India.
Negrito means "little black people" in Spanish (negrito is the Spanish diminutive of negro, i.e., "little black person"); it is what the Spaniards called the aboriginal people that they encountered in the Philippines. The term Negrito itself has come under criticism in countries like Malaysia, where it is now interchangeable with the more acceptable Semang, although this term actually refers to a specific group.
They have dark skin, often curly-hair and Asiatic facial characteristics, and are stockily built.
Negritos in the Philippines frequently face discrimination. Because of their traditional hunter-gatherer lifestyle, they are marginalized and live in poverty, unable to find employment.
Europe
Western Europe
France
While census collection of ethnic background is illegal in France, it is estimated that there are about 2.5 – 5 million black people residing there.
Germany
As of 2020, there are approximately one million black people living in Germany.
Netherlands
Afro-Dutch are residents of the Netherlands who are of Black African or Afro-Caribbean ancestry. They tend to be from the former and present Dutch overseas territories of Aruba, Bonaire, Curaçao, Sint Maarten and Suriname. The Netherlands also has sizable Cape Verdean and other African communities.
