Miscegenation is marriage or admixture between people who are members of different races. The word was coined in English from Latin () and (). Interracial relationships have profoundly influenced various regions throughout history. Africa has had a long history of interracial mixing with non-Africans, since prehistoric times, with migrations from the Levant leading to significant admixture. This continued into antiquity with Arab and European explorers, traders, and soldiers having relationships with African women. Mixed-race communities like the Coloureds in South Africa and Basters in Namibia emerged from these unions.

In the Americas and Asia, similar patterns of interracial relationships and communities formed. In the United States, historical taboos and laws against interracial marriage evolved, culminating in the landmark Loving v. Virginia case in 1967. Latin America, particularly Brazil, has a rich history of racial mixing, reflected in its diverse population. In Asia, countries like India, China, and Japan experienced interracial unions through trade, colonization, and migration, contributing to diverse genetic and cultural landscapes.

In Europe, Nazi Germany's anti-miscegenation laws sought to maintain "racial purity," specifically targeting Jewish-German unions. Hungary and France saw mixed marriages through historical conquests and colonialism, such as between Vietnamese men and French women during the early 20th century.

In Oceania, particularly Australia and New Zealand, dynamics varied; Australia had policies like the White Australia policy and practices affecting Indigenous populations, while New Zealand saw significant Māori and European intermarriages. In the Middle East, inter-ethnic relationships were common, often involving Arab and non-Arab unions. Portuguese colonies encouraged mixed marriages to integrate populations, notably seen in Brazil and other territories, resulting in diverse, multicultural societies.

Africa Africa has had a long history of mixing with non-Africans since prehistoric times. The Eurasian backflow, which happened in prehistoric times, saw a huge migration from the Levant entering the region and these migrants mixing with the native Africans. Signs of this migration can be found among the people inhabiting the Horn of Africa and Sudan. Africa in antiquity, also has had long history of interracial mixing with male Arab and European explorers, traders and soldiers having sexual relations with black African women as well as taking them as wives.

Sir Richard Francis Burton writes, during his expedition to Africa, about relationships between black women and white men: "The women are well disposed toward strangers of fair complexion, apparently with the permission of their husbands." There are several mixed race populations throughout Africa mostly the results of interracial relationships between Arab and European men and black women. In South Africa, there are big mixed race communities like the Coloureds and Griqua formed by White colonists taking native African wives. In Namibia there is a community called the Rehoboth Basters formed by the interracial marriage of Dutch/German men and black African women.

In the former Portuguese Africa (now known as Angola, Mozambique and Cape Verde) racial mixing between white Portuguese and black Africans was fairly common, especially in Cape Verde where the majority of the population is of mixed descent.

There have been some recorded cases of Chinese merchants and labourers taking African wives throughout Africa as many Chinese workers were employed to build railways and other infrastructural projects in Africa. These labour groups were made up completely of men with very few Chinese women coming to Africa.

In West Africa, especially Nigeria there are many cases of non-African men taking African women. Many of their offspring have gained prominent positions in Africa. Flight Lieutenant Jerry John Rawlings, who had a Scottish father and a black Ghanaian mother became the president of Ghana. Jean Ping, the son of a Chinese trader and a black Gabonese mother, became the deputy prime minister as well as the foreign minister of Gabon and was the Chairperson of the Commission of the African Union from 2009 to 2012. The president of Botswana, Ian Khama, is the son of Botswana's first president, Seretse Khama, and a white British student, Ruth Williams Khama. Nicolas Grunitzky, who was the son of a white German father and a Togolese mother, became the second president of Togo after a coup.

Indian men, who have long been traders in East Africa, sometimes married among local African women. The British Empire brought many Indian workers into East Africa to build the Uganda Railway. Indians eventually populated South Africa, Kenya, Uganda, Tanzania, Malawi, Rwanda, Zambia, Zimbabwe and Zaire in small numbers. These interracial unions were mostly unilateral marriages between Indian men and East African women.

Many Chinese men working in Africa have married Black African women in Angola, South Africa, Gabon, Tanzania, Côte d'Ivoire, Kenya, Lagos in Nigeria, Congo & Ethiopia and fathered children with them.

Africa has a long history of interracial mixing with Arabs and later Europeans having sexual relations with black Africans. Arabs played a big role in the African slave trade and unlike the trans-Atlantic trade most of the enslaved Africans in the Arab slave trade were women. Most of them were used as sexual slaves by the Arab men and some were taken as wives.

In the former Lusophone Africa (now known as Angola, Mozambique and Cape Verde) racial mixing between white Portuguese and black Africans was fairly common, especially in Cape Verde, where the majority of the population is of mixed descent.

West Africa In West Africa, a series of interracial marriages and relationships created a number of mixed race families in the various countries of the region.

In Sierra Leone, marriages between representatives of British trading firms and princesses of the Sherbro people created a number of aristocratic families such as the Sherbro Tuckers and the Sherbro Caulkers. Due to matrilineality, they have maintained their claims to their ancestral thrones.

In Benin, meanwhile, the descendants of the Brazilian slave trader Francisco Félix de Sousa and his harem of black consorts have contributed a number of prominent citizens. Figures such as a president (Paul-Émile de Souza) and a first lady (Chantal de Souza Boni Yayi, President de Souza's niece) are arguably the most notable of them.

In Gabon, a woman by the name of Germaine Anina - daughter of a Gabonese tribal chief - married a Chinese trader and politician named Cheng Zhiping. Their son, Jean Ping, went on to serve as a minister in his mother's native country.

In orthodox Serer religion and custom, interfaith and interracial marriages are forbidden. Banishment and disinheritance may be levied against a Serer who fails to follow these customary teachings.Ndiaye, Ousmane Sémou, "Diversité et unicité Sérères: L'Exemple Le de la Région de Thiès", [in] Ethiopiques n°54, revue semestrielle, de culture négro-africaine, Nouvelle série volume 7., 2e semestre (1991) (retrieved 8 March 2020) The Serer-Noon (a sub-group of the Serer people) strongly adhere to these teachings. It was for this reason that the first Senegalese president Léopold Sédar Senghor did not receive support from the Serer community, especially the ultra-traditional Serer. Although born to an aristocratic Serer family, he did not receive support from the Serer community due to his marriage to his French wife. Instead, he was supported by other ethnic groups such as the Wolof and Fula. In return, Senghor failed to develop Serer villages and towns.Jeetaay (Thursday, 28 March 2019) [in] the Seereer Resource Centre and Seereer Radio (retrieved 8 March 2020)

Southern Africa There is a significant mixed race population, the result of mostly European and African unions, in South Africa, called Coloureds. The term Coloured is also used to describe persons of mixed race in the neighbouring nation of Namibia, to refer to those of part Khoisan, part black and part white descent. The Basters constitute a separate ethnic group that are sometimes considered a sub-group of the Coloured population of the country.

Some of the Xhosa people claim descent from white people. The royal family of the ImiDushane, for example, is descended from Queen Gquma of the Mpondo, a white orphan that was adopted by a Xhosa chief after a shipwreck killed her parents. She later married an Mpondo prince, became his great wife, and served as queen during his reign as king of the Tshomane Mpondo.

Interracial marriage was banned under apartheid. Due to this, there was considerable opposition to the marriage between Sir Seretse Khama, Paramount Chief of the Bamangwato Tswanas, and his eventual wife Ruth Williams Khama, Lady Khama, even though Chief Khama was Motswana and not South African.

Today there are a number of high-profile interracial couples in Southern Africa, such as the unions of Mmusi Maimane (a black opposition politician who served as the Leader of the Opposition of South Africa), Nyaniso Dzedze (a black actor) and his German wife Yana Fay Dzedze, Matthew Booth (a white soccer player) and his wife Sonia Bonneventia (a black former Miss South Africa first princess and international model)Simon Austin: South Africa's white knight.

Ghana Many Chinese men who engaged in gold mining in Ghana married local Black African Ghanaian women and had children with them and then the Ghana government deported illegal miners, leaving the mixed race Chinese fathered children stranded in Ghana while their fathers were sent back to China.

In Ghana, a number of founding fathers had relationships with foreigners of other races: Kwame Nkrumah married the Egyptian Copt Fathia Nkrumah and raised a family with her. Their children would go on to become politicians like their father. President Nkrumah's contemporary and sometime friend, Joe Appiah, was himself married to the British debutante Peggy Cripps Appiah. At the start of the 21st century, their descendants were being led by their only son, Kwame Anthony Appiah. In addition to this, Dr. J. B. Danquah had a son with a British woman during his time in Britain. He would go on to become noted actor Paul Danquah.

Kenya

Many Ugandan women have been marrying Chinese businessmen who moved to Uganda.

Early Chinese mariners had a variety of contacts with Kenya. Archaeologists have found Chinese porcelains made during the Tang dynasty (618–907) in Kenyan villages; however, these were believed to have been brought over by Zheng He during his 15th century ocean voyages. On Lamu Island off the Kenyan coast, local oral tradition maintains that 20 shipwrecked Chinese sailors with 400 survivors,Zheng He's Voyages Down the Western Seas,
