Ancient DNA Restores the Origin Story of the Swahili People

KR:  The theory of African migration hangs down further. Latest archaeology
of SWAHILI language east African originated from Persia to India on
migration. It is reported that Swahili people were only non-Swahili people
2 lakh years before. Even if it is a guess out of the DNA analysis, the
theory of Poecocke the Greek in the book Greece, gets confirmed; the
migration after the Mahabharatha war to Iran and Greece and then to Africa.
Now the findings saw yesterday:

1   THE LEGACY OF THE MEDIEVAL Swahili civilization is a source of
extraordinary pride in East Africa, as reflected in its language being the
official tongue of Kenya, Tanzania, and even inland countries like Uganda
and Rwanda, far from the Indian Ocean shore where the culture developed
nearly two millennia ago.

Its ornate stone and coral towns hugged 2,000 miles (3,200 kilometers) of
the coast, and its merchants played a linchpin role in the lucrative trade
between Africa and lands across the ocean: Arabia, Persia, India, Southeast
Asia, and China.

By the turn of the second millennium, Swahili people embraced Islam, and
some of their grand mosques still stand at the UNESCO World Heritage sites
of Lamu in Kenya <https://whc.unesco.org/en/list/1055/> and Kilwa in
Tanzania <https://whc.unesco.org/en/list/144>.

Self-governance ended following Portuguese colonization in the 1500s, with
control later shifting to the Omanis (1730-1964), Germans in Tanganyika
(1884-1918), and British in Kenya and Uganda (1884-1963). Following
independence, coastal peoples were absorbed into the modern nation-states
of Somalia, Kenya, Tanzania, Mozambique, and Madagascar.

So who were the Swahili people, and where did their ancestors originally
come from? Ironically, the story of Swahili origins has been moulded almost
entirely by non-Swahili people, a challenge shared with many other
marginalized and colonized peoples who are the modern descendants of
cultures of the past with extraordinary achievements.

Working with a team of 42 colleagues, including 17 African scholars and
multiple members of the Swahili community, we’ve now published the first
ancient DNA sequences from peoples of the Swahili civilization
<https://doi.org/10.1038/s41586-023-05754-w>. Our results do not provide
simple validation for the narratives previously advanced in archaeological,
historical, or political circles. Instead, they contradict and complicate
all of them.

Western archaeologists in the mid-20th century emphasized the connections
of the medieval Swahili to Persia and Arabia
<https://www.worldcat.org/title/1174314>, sometimes suggesting that their
impressive achievements <https://www.worldcat.org/title/1672964> could not
have been attained by Africans
<https://www.publicmedievalist.com/recovering-medieval-africa/>.

Post-colonial scholars, including one of us (Kusimba
<https://scholar.google.com/citations?user=5NehBh4AAAAJ&hl=en&oi=ao>),
pushed back against that view. Earlier researchers had inflated the
importance of non-African influences by focusing on imported objects at
Swahili sites. They minimized the vast majority of locally made materials
and what they revealed about African industry and innovation

But viewing Swahili heritage as primarily African or non-African is too
simplistic. In fact, both perspectives are by-products of colonialist
biases.

The truth is that colonization of the East African coast did not end with
the departure of the British in the middle of the 20th century. Many
colonial institutions were inherited and perpetuated by Africans

As modern nation-states formed, with governments controlled by inland
peoples, Swahili people continued

 to be undermined
<https://iupress.org/9780253210548/plundering-africas-past/> politically
and economically, in some cases as much as they had been under foreign rule.

Decades of archaeological research in consultation with local people aimed
to address the marginalization of communities of Swahili descent. Our team
consulted oral traditions and used ethnoarchaeology and systematic surveys,
along with targeted excavations of residential, industrial, and cemetery
locations. Working with local scholars and elders, we unearthed materials
such as pottery, metal, and beads; food, house, and industrial remains; and
imported objects such as porcelain, glass, glass beads, and more. Together
they revealed the complexity of Swahili everyday life and the peoples’
cosmopolitan Indian Ocean heritage.

Ancient DNA analysis was always one of the most exciting prospects. It
offered the hope of using scientific methods to obtain answers to the
question of how medieval people are related to earlier groups and to people
today, providing a counterweight to narratives imposed from outside. Until
a few years ago, this kind of analysis was a dream. But because of a
technological
revolution in 2010 <https://reich.hms.harvard.edu/why-i-wrote-book>, the
number of ancient humans with published genome-scale data has risen from
nothing to more than 10,000 today
<https://reich.hms.harvard.edu/allen-ancient-dna-resource-aadr-downloadable-genotypes-present-day-and-ancient-dna-data>
.

We worked with local communities to determine the best practices for
treating human remains in line with traditional Muslim religious
sensitivities. Cemetery excavations, sampling, and reburial of human
remains were carried out in one season, rather than dragging on
indefinitely.

Our team generated data from more than 80 people, mostly elite individuals
buried in the rich centers of the stone towns. We will need to wait for
future work to understand whether their genetic inheritance differed from
people without their high status.

Contradicting what we had expected, the ancestry of the people we analyzed
was not largely African or Asian. Instead, these backgrounds were
intertwined, each contributing about half of the DNA of the people we
analyzed.

We found that Asian ancestry in the medieval individuals came largely from
Persia (modern-day Iran), and that Asians and African ancestors began
mixing at least 1,000 years ago. This picture is almost a perfect match to
the Kilwa Chronicle
<https://www.thoughtco.com/kilwa-chronicle-sultan-list-swahili-culture-171631>,
the oldest narrative told by the Swahili people themselves, and one almost
all earlier scholars had dismissed <https://doi.org/10.2307/3171745> as a
kind of fairy tale.

Another surprise was that, mixed in with the Persians, Indians were a
significant proportion of the earliest migrants. Patterns in the DNA also
suggest that, after the transition to Omani control in the 18th century,
Asian immigrants became increasingly Arabian. Later, there was
intermarriage with people whose DNA was similar to others in Africa. As a
result, some modern people who identify as Swahili have inherited
relatively little DNA from medieval peoples like those we analyzed, while
others have more.

One of the most revealing patterns our genetic analysis identified was that
the overwhelming majority of male-line ancestors came from Asia, while
female-line ancestors came from Africa. This finding must reflect a history
of Persian males traveling to the coast and having children with local
women.

One of us (Reich <https://reich.hms.harvard.edu/>) initially hypothesized
that these patterns might reflect Asian men forcibly marrying African
women, because similar genetic signatures in other populations are
known to reflect
such violent histories
<https://nautil.us/social-inequality-leaves-a-genetic-mark-237027/>. But
this theory does not account for what is known about the culture, and there
is a more likely explanation.

*Traditional Swahili society places much economic and social power in the
hands of women.*

Traditional Swahili society is similar to many other East African Bantu
cultures in being substantially matriarchal
<https://www.jstor.org/stable/45341518>: It places much economic and social
power in the hands of women. In traditional Swahili societies even today,
ownership of stone houses often passes down the female line
<http://www.siupress.com/books/978-0-8093-3397-4>. And there is a long
recorded history of female rulers, beginning with Mwana Mkisi, ruler of
Mombasa, as recorded by the Portuguese as early as the 1500s, down to
Sabani binti Ngumi, ruler of Mikindani in Tanzania as late as 1886.

Our best *guess *is that Persian men allied with and married into elite
families and adopted local customs to enable them to be more successful
traders. The fact that their children passed down the language of their
mothers, and that encounters with traditionally patriarchal Persians and
Arabians and conversion to Islam did not change the coast’s African
matriarchal traditions, confirms that this was not a simple history of
African women being exploited. African women retained critical aspects of
their culture and passed it down for many generations.

How do these results gleaned from ancient DNA restore heritage for the
Swahili? Objective knowledge about the past has great potential to help
marginalized peoples. By making it possible to challenge and overturn
narratives imposed from the outside for political or economic ends,
scientific research provides a meaningful and underappreciated tool for
righting colonial wrongs.
