In early 2026, planes have been landing in Tel Aviv carrying people who left behind everything they owned in the remote border states of Northeast India. They believe, with total conviction, that they are descendants of one of the lost tribes of Israel, exiled from their homeland twenty-seven centuries ago. No one has ever proven that belief with DNA. Yet, a few hundred kilometers away on a different Indian coastline, an entirely separate Jewish community spent decades being told by Israel’s religious authorities that they might not be Jewish at all, until a genetics lab eventually handed them the exact proof the other group still does not have.
Same country, same ancient identity being claimed, two completely different verdicts from the same science. India is not a country most people associate with Jewish history, which is exactly why almost nobody knows it is home to several separate, unrelated Jewish communities, each with its own centuries-old legend about how it got there. On the western coast, centered around Mumbai in the Konkan region of Maharashtra, lives a community called the Bene Israel. Their own oral tradition says their ancestors were the only seven survivors of a shipwreck, refugees fleeing persecution in the ancient land of Israel, whose vessel sank just off the Konkan shoreline.
Scholars disagree wildly on when that shipwreck supposedly happened, with estimates ranging from the 8th century BCE to the 6th century CE, a spread of over a thousand years that reveals how little verifiable history anyone had to work with before modern genetics. Cut off from world Jewry for what may have been over a thousand years, the Bene Israel held onto a small core of Jewish practice, keeping the Sabbath, observing certain dietary laws, reciting the Shema, while losing almost everything else, including Hebrew itself, until Baghdadi Jewish traders and later Christian missionaries reestablished contact in the 18th century. For generations before that reconnection, their neighbors simply called them Shanwar Teli, meaning Saturday oil pressers, because although they worked the same oil pressing trade as everyone else in the region, they refused consistently to work on Saturdays. A small stubborn habit repeated across dozens of generations turned out to be one of the clearest outward signs of a hidden identity, long before anyone thought to look at their DNA.
Further south along the Malabar Coast in what is now Kerala, an entirely separate and much older Jewish community formed around the city of Cochin with its own synagogues, legends, and layered internal history. Some Cochin Jewish families trace their arrival to ancient trade contact reaching back to the era of the biblical King Solomon. Others linked their community’s founding to refugees who fled the Roman destruction of the Second Temple in the 1st century CE. Over the centuries, the community grew into two distinct groups, informally referred to as black Jews and white Jews, a division based on skin tone and length of residence in India, in which the more recently arrived lighter-skinned Paradesi Jews from Europe and the Middle East generally held higher social standing and even worshipped in separate synagogues from the older Malabari Jewish community.
When large numbers of both communities immigrated to the newly founded state of Israel after 1948, something uncomfortable happened almost immediately. Some of Israel’s most senior religious authorities openly questioned whether the Bene Israel in particular were, in a strict legal sense, actually Jewish at all. The doubt went deep enough that by the early 1960s, Israel’s Chief Rabbinate formally instructed marriage registrars to individually investigate the ancestry of Bene Israel applicants before granting marriage licenses, forcing ordinary families to prove, case by case, that their own grandparents had genuinely been Jewish. The policy was eventually dropped, but it left behind a wound of suspicion that lasted for years.
For a long time, science could not resolve the argument either. The earliest genetic evidence was genuinely contradictory. Researchers studying mitochondrial DNA, passed down strictly through the maternal line, found that Bene Israel maternal ancestry was overwhelmingly local Indian, showing barely any connection to Middle Eastern Jewish populations. That result seemed to hand a win to the skeptics.
But a separate team studying the Y chromosome, passed down strictly through the paternal line, found something pointing in almost the opposite direction. A genetic pattern called the Cohen Modal Haplotype, found at unusually high frequency among Jewish priestly lineages worldwide, showed up among Bene Israel men too, hinting at a genuine paternal link to the Middle East, though that study rested on a sample of only four men. Broader analysis of the rest of the genome kept coming back ambiguous. Three separate genetic methods, three different, partly contradictory answers.
Then, in 2016, everything changed. A team of researchers from Tel Aviv University, Cornell University, and the Albert Einstein College of Medicine published a study in the journal PLoS One that cut through the noise. Rather than relying on one isolated genetic marker at a time, the team ran a full genome-wide analysis, comparing tens of thousands of genetic markers across the entire Bene Israel genome against Ashkenazi Jewish populations, other Jewish diaspora communities, and detailed reference data on Indian population genetics. This time, the picture snapped into focus with real statistical confidence.
The Bene Israel carry both substantial genuine Jewish ancestry and substantial Indian ancestry, woven together across the whole genome. The researchers even calculated roughly when that mixing occurred, using patterns of genetic recombination that function almost like a molecular stopwatch. Their estimate placed the admixture event between 19 and 33 generations back, translating to somewhere around 650 to just over 1,000 years ago. The most likely explanation, according to the research team, is that a group of Middle Eastern Jewish men arrived on the Konkan coast roughly 1,000 years ago, married local Indian women, and their descendants then kept marrying almost exclusively within their own small, tight-knit community for centuries, locking that specific mixed genetic signature in place and carrying it forward, largely unchanged, to today.
Related genetic research on the Cochin Jewish community turned up a broadly similar pattern, real Jewish ancestry mixed with real Indian ancestry, though tied to its own separate historical timeline and its own distinct founding events. The same broader research effort also examined the Beta Israel community of Ethiopia, a population that had likewise practiced forms of Judaism for centuries in isolation from the rest of world Jewry. When researchers ran comparable genome-wide analysis, the results told a noticeably different story. Genetically, the Beta Israel clustered closely with the non-Jewish Ethiopian population surrounding them, without the same kind of clear, datable admixture signal pointing back to a Middle Eastern founding population that appeared in the Bene Israel study.
That does not erase the Beta Israel’s long, genuine religious and cultural history. It simply shows that genetics does not hand out the same kind of answer to every community that has spent centuries identifying as Jewish in isolation. Which brings us to the part of this story that is still completely unresolved. Thousands of kilometers northeast of Mumbai and Kerala, in India’s remote border states of Manipur and Mizoram, a very different community has spent the last several decades claiming an entirely different, far older biblical connection.
They call themselves the Bnei Menashe, meaning children of Manasseh, after one of the 10 tribes of the ancient kingdom of Israel exiled by the Assyrian Empire around 722 BCE and never definitively accounted for again, the so-called lost tribes of Israel. When the Assyrians conquered the northern kingdom of Israel, they deported large portions of its population deep into their empire, and the historical trail for those 10 northern tribes went completely cold. For more than 2,000 years, communities scattered from Ethiopia to Afghanistan to Japan have claimed descent from these vanished tribes. Drawn from Mizo, Kuki, and Chin ethnic groups speaking Tibeto-Burman languages with no obvious linguistic or cultural connection to the ancient Middle East, the Bnei Menashe were converted to Christianity by British missionaries during the 19th and early 20th centuries.
Then, starting around 1951, a local spiritual leader reported a vision revealing that his people were the long-lost descendants of ancient Israelites, a claim that slowly grew into a genuine grassroots religious movement with thousands of community members eventually abandoning Christianity in favor of what they had come to believe was their true ancestral faith. The Bnei Menashe’s Jewish self-identification only emerged after their exposure to Christian missionary teaching about the Bible, an origin story that immediately raised questions among geneticists and historians. That skepticism led directly to genetic testing. In 2003, roughly 350 genetic samples were collected from Bnei Menashe men and women and sent to Israel, where researchers at the Technion analyzed them specifically to look for the same kind of Middle Eastern genetic signature that had confirmed a real ancestral connection in the Bene Israel’s case.
The results did not deliver anything close to that same clear answer. The testing did not yield conclusive evidence of Middle Eastern ancestry, and broader academic reviews have continued describing the genetic picture as inconclusive ever since, even as occasional smaller-scale follow-up studies have reported an intriguing but far from definitive maternal genetic marker in a handful of women. None of that scientific ambiguity has slowed the real-world consequences. In 2005, Israel’s Sephardic Chief Rabbi formally recognized the Bnei Menashe as descendants of one of the lost tribes, opening a path toward religious conversion and eventual immigration to Israel under the country’s law of return, actively pursued by an organization called Shavei Israel, which has already helped bring several thousand Bnei Menashe members to Israel.
Following a wave of deadly ethnic violence in Manipur since 2023 between the Meitei majority and the Kuki minority, violence that displaced thousands and killed well over 200 people, the Israeli government approved an ambitious relocation plan in late 2025 to bring roughly 6,000 remaining Bnei Menashe community members to Israel under an operation named Wings of Dawn. New arrivals have been landing in Tel Aviv throughout early 2026, driven as much by urgent physical safety concerns in a homeland torn apart by ethnic conflict as by any deep spiritual pull toward a Jewish identity that, genetically speaking, science still cannot fully confirm or deny. So where does that leave the actual answer to India’s centuries-old Jewish DNA mystery? It depends entirely on which community you ask about.
For the Bene Israel, modern genome-wide DNA analysis has confirmed, with real statistical confidence, that they carry substantial genuine ancestry tracing back to the Middle East mixed with equally substantial Indian ancestry, locked together roughly a thousand years ago and preserved ever since. For the Bnei Menashe, that same kind of clear vindication simply has not arrived. Their claim rests far more heavily on 20th century religious conviction and, now urgently, on the desperate practical need for safety amid ethnic conflict than on any confirmed genetic thread reaching back to ancient Israel. Genetics can only find what is actually recoverable inside a genome, and how clearly it can find it depends entirely on how the mixing happened, how long ago it happened, and how much later intermarriage or population movement has blurred the original signal.
A relatively recent, concentrated admixture event like Middle Eastern men marrying into a small coastal Indian community roughly a thousand years ago leaves behind exactly the kind of clean, datable genetic signature that modern statistical tools are very good at detecting. A vaguer, much older, more diffuse claim of descent spread across a Tibeto-Burman speaking population may simply not have left behind anything a genome-wide test can cleanly pick out. Science answering one identity question decisively and staying silent on another is not evidence that one community’s faith matters more than the others. It is evidence of what a genome can and cannot preserve across very different amounts of time.
DNA gave the Bene Israel an actual datable peer-reviewed answer to a question that had shadowed their community for generations. It has not yet given the Bnei Menashe that same certainty, and given how their history unfolded, it may never fully manage to. But thousands of them are boarding planes to Israel anyway, right now, carrying a belief that predates any DNA test, and for many of them, no longer depends on one either.
