Kongo DNA
Genetic origins and closest populations · DR Congo and Angola · Sub-Saharan Africa
The Kongo people live along the lower Congo River, in western DR Congo, northern Angola and the Republic of the Congo, and speak Kikongo, a Bantu language. Their kingdom, centred on Mbanza Kongo, was one of the great states of Central Africa, in contact with Portugal from 1483, and many people from the region were taken to the Americas. In our model, the Kongo average is 80.1% West African, 10.1% Western rainforest forager (BiAka) and 9.8% Nilotic East African. That BiAka share is the highest in our atlas after the BiAka themselves, a trace of contact with rainforest foragers. The ancient matches are unusually local: after 19th-century people buried on Saint Helena (0.0201), the closest groups come from Kindoki and Ngongo Mbata in the lower Congo region, dated to around 1700 to 1750 (0.0234 and 0.0301). The closest modern averages are Kongo from the Republic of the Congo, the Ganguela of Angola and Cameroonian Bantu speakers.
- Ancient components in our model: West African 80.1%, Western rainforest foragers (BiAka) 10.1%, Nilotic East African 9.8%
- Closest other population in our data: Ganguela, distance 0.0130
- Closest ancient group in our data: Saint Helena Late Modern Rupert's Valley (Central/Southern African Bantu Profile), distance 0.0201
Kongo is one of the 335 modern populations in our population genetics atlas. The numbers on this page describe the average Global25 (G25) genome of the Kongo individuals sampled in DR Congo and Angola. Like every population average, it smooths over a lot of variation between individuals.
Ancient make-up of the Kongo average
Modelled as a mix of deep ancestral reference populations, the Kongo average comes out as 80.1% West African, 10.1% Western rainforest foragers (BiAka) and 9.8% Nilotic East African. The West African component reflects ancestry from sub-Saharan Africa. With well over half of the total, this single source dominates the profile.
The fit is acceptable (fit distance 0.038): treat the proportions as a good approximation rather than exact values. This population was modelled with a global set of reference populations (ancient genomes, plus modern stand-ins where no suitable ancient genome exists), because West Eurasian sources alone cannot describe it.

Closest modern populations to Kongo
Ranking every modern population by genetic distance puts Kongo (Republic of the Congo) first for Kongo, at 0.012, then Ganguela and Cameroonian (Bantu). Leaving aside the other regional samples listed under the same name in the G25 sheet, the nearest other populations are Ganguela (0.013), Cameroonian (Bantu) (0.014) and Umbundu (0.015). Even the tenth closest, Mbo, is only 0.023 away: Kongo belongs to a dense cluster of related populations, so small differences inside that cluster should not be over-interpreted.

Distances are Euclidean distances between averaged G25 coordinates. On our scale, below 0.025 is very close, below 0.050 close, below 0.080 moderate, and beyond that distant.
Closest ancient populations to Kongo
If we search ancient DNA for the best match to Kongo, Saint Helena Late Modern Rupert's Valley (Central/Southern African Bantu Profile) (Late Modern, c. 1800-1950 AD) comes first, at 0.020, with Democratic Republic of the Congo Kindoki 230BP next. That is a very close match, which suggests strong genetic continuity between those ancient people (or close relatives of theirs) and the modern population. A close ancient match is not proof of direct descent: it means those individuals carried a similar overall mix of ancestry.

Ancient DNA from DR Congo
Our ancient DNA database holds 5 individuals excavated in present-day DR Congo, dated from about 1184 AD to 1810 AD. The most frequent Y-DNA haplogroups among them are E1b (2), E (1) and R1b (1), and the most frequent mtDNA haplogroups are L1 (2) and L0 (1). These are people who lived on the same land in the past, not necessarily ancestors of today's Kongo population.

About these numbers
A word of caution: these figures describe the average of the Kongo individuals who were sampled, not every person who identifies as Kongo. Individuals vary around that average, and identity is about history, language and family, not about a genetic score. Read this page as a map of deep ancestry, not as a definition.
Method: averaged G25 coordinates, Euclidean distances to other modern and ancient averages, and a non-negative least-squares model against deep ancestral reference populations (data generated 2026-10-01). Read the full method.

Frequently asked questions
What is the ancient genetic make-up of Kongo?
Modelled with deep ancestral reference populations, the Kongo average is about 80.1% West African, 10.1% Western rainforest foragers (BiAka) and 9.8% Nilotic East African. These proportions are model estimates for a group average, not exact values for any one person.
Which populations are genetically closest to Kongo?
Leaving aside other regional samples listed under the same name in the G25 sheet (such as Kongo (Republic of the Congo)), the closest modern populations to the Kongo average are Ganguela, Cameroonian (Bantu) and Umbundu. The closest ancient matches are Saint Helena Late Modern Rupert's Valley (Central/Southern African Bantu Profile), Democratic Republic of the Congo Kindoki 230BP and COG Kindoki 230BP.
Can a DNA test tell me if I am Kongo?
No DNA test can confirm an ethnicity or a nationality. What DNA can show is how similar your genome is to the sampled Kongo average and to its neighbours. If you have G25 coordinates, paste them in the comparison box on this page to check that for free.
Which ExploreYourDNA report suits Kongo ancestry?
Sankofa – African Ancestry Report is the report built for this heritage, and its reference panel fits the Kongo average closely. Your own DNA may differ from the average, so the free Report Finder checks every report against your file before you buy.
Where does the data on this page come from?
From the averaged Global25 (G25) coordinates of the sampled individuals: genetic distances to other modern and ancient population averages, and a non-negative least-squares model against deep ancestral reference populations.
