A German town built a granary atop its Jewish cemetery. Now the bones are yielding insights about Ashkenazi DNA.
BERLIN (JTA) – The city of Erfurt in central Germany is home to an impeccably restored medieval synagogue made possible because local Jews had been expelled long before the Nazis began their campaign to destroy Jewish sites.
Now, Erfurt’s long-hidden Jewish past is again offering new insights — this time about the genetic history of Ashkenazi Jews.
Human remains from a medieval Jewish cemetery in Erfurt have allowed what researchers say is the largest ancient Jewish DNA study to date. Conducted without disinterring any remains, in keeping with Jewish law, the study published Wednesday in the scientific journal Cell found that Erfurt’s medieval Jewish community was more genetically diverse than their modern-day cousins, and carried many of the same Jewish genetic diseases — such as Tay Sachs and cystic fibrosis — that affect Ashkenazi Jews today.
“There have been many previous DNA studies, but not of Jews,” said geneticist Shai Carmi, a professor at the Hebrew University of Jerusalem, whose search for study material led him to an archaeological dig at the Jewish cemetery in Erfurt. He and his collaborators were able to analyze DNA of 33 individuals who died between 1270 and 1400, using teeth they found there.
The study follows a similar analysis revealed in August by researchers in England, who studied the DNA from skeletons found at the bottom of a medieval well and concluded that the remains were likely of victims of an antisemitic massacre in 1190. Analysis of six individuals prior to their identification as Jewish revealed that Ashkenazi Jews developed a unique genetic variation centuries earlier than realized.
The Erfurt analysis also includes samples from before the epidemic of Black Death that was until recently understood to have created the genetic “bottleneck” that created the genetic markers common among Ashkenazi Jews today.
Erfurt’s Jewish settlement existed from the 11th to 15th century, with a brief gap following a 1349 massacre perpetrated after the Jews were falsely blamed for causing the bubonic plague. Surviving Jews returned there, but after all Jews were expelled once and for all in 1454, the city built a granary on top of the Jewish cemetery.

In 2013, the city approved the repurposing of the unused granary into a parking lot. Because it was an historic site, a rescue excavation was initiated, overseen for the State of Thuringia by German archaeologist Karin Sczech.
Meanwhile, Carmi had been looking for Jewish cemeteries anywhere in the world “where we could analyze remains already excavated,” he told JTA in a telephone interview from Jerusalem. “I consulted historians and eventually reached the archeologist in Erfurt.” Fortunately, he said, “they still hadn’t reburied the remains.”
He approached Sczech, who later became a co-author of the new study. In 2018, with a supportive judgment from Rabbi Ze’ev Litke — an Israeli expert on genetics and Jewish law — and permission from Erfurt’s then-rabbi, Benjamin Kochan, work began to extract and analyze DNA from detached teeth found in the graves. (About 500 Jews live in Erfurt today, most of them having migrated from the former Soviet Union since 1990.)
American geneticist David Reich picked up the teeth and brought them back to the department of human evolutionary biology at Harvard University in Cambridge, Massachusetts, where drilling and DNA extraction took place.
While the skeletons were reburied, the teeth are still stored at the research institutes where they have been analyzed, in case scientists need to retest to verify the result.
The project provides an ethical basis for studies of ancient Jewish DNA, Carmi said. “Of course we couldn’t just go to a cemetery and dig and take out skeletons; this would be prohibited,” he said, referring to Jewish law prohibiting the removal of bones from where someone was buried.
But Litke opined that the study could be done, because the bones already had been disturbed for an unrelated reason. “He recommended using teeth, as the analysis does almost no damage,” Carmi said.
There are many motivations to study Jewish DNA: One can find lost relatives going back a few generations, and answer questions about Jewish origin of partners intending to marry. But the goal of Carmi’s team was “to fill the gaps in our understanding of Ashkenazi Jewish early history.”
There are several non-destructive ways to obtain DNA from human remains, said Carmi, who also works as a consultant to an Israeli firm that helps clients trace their genetic roots.
“You can take an almost microscopic slice of bone and extract DNA in a solution, or put the entire bone in a solution and extract the DNA without drilling, without disturbing the dead. This opens the way to doing studies even without teeth,” he added.
His team found that the Erfurt community appeared to fit into two genetically distinct groups, descending either from Middle Eastern or European populations. This genetic variability no longer exists, Carmi said.
At the same time, Carmi said, the analysis found remarkable continuity in the local community, as well. “One third of the Erfurt individuals descended from one woman through their maternal lines,” he said, adding that evidence suggested that she lived between 1,000 and 2,000 years ago.
In a press statement, geneticist Reich of Harvard said the work “also provides a template for how a co-analysis of modern and ancient DNA data can shed light on the past. Studies like this hold great promise not only for understanding Jewish history, but also that of any population.”
The research team, with more than 30 scientists, included Hebrew University’s Shamam Waldman, a doctoral student in Carmi’s group, who performed most of the data analysis.

Ro Khanna and Thomas Massie team up to strip US-Israel military tech cooperation from defense bill
(JTA) — In one of the latest examples of political extremes converging over Israel, Reps. Ro Khanna and Thomas Massie joined forces this week to challenge a provision expanding U.S.-Israel defense cooperation.
Khanna, a progressive California Democrat, and Massie, a Kentucky Republican, both said over the weekend that they would seek to remove a provision from the House’s annual defense bill that would expand U.S.-Israeli defense technology cooperation.
“If the provision in the NDAA to integrate/synchronize the U.S. and Israeli militaries (section 224) makes it out of committee, I’ll offer an amendment to strip it from the bill on the floor,” Massie, who lost his bid for reelection last month against a President Donald Trump-endorsed primary opponent, wrote in a post on X. “We are a sovereign country…”
The section of the National Defense Authorization Act for 2027 that Khanna and Massie have taken aim at would require the Secretary of Defense to designate an “executive agent responsible for synchronizing cooperative efforts between the United States and Israel, including bilateral defense technology research, development, testing, evaluation, integration, and industrial cooperation.”
The cross-ideological alliance marked the latest instance of the progressive Democrat and libertarian Republican finding common cause on Israel-related foreign policy, after the pair previously teamed up to oppose U.S. involvement in Israel’s war in Iran last year.
The pledge by Massie, a leading anti-Israel Republican in Congress, was quickly joined by Khanna, who has been staunchly critical of Israel’s conduct during the war in Gaza and recently opposed American funding for Israel’s Iron Dome defense system.
“And I will be offering an amendment in the committee itself to strip section 224 out, @RepThomasMassie,” Khanna wrote in a post on X. “Trump can’t kill the Massie/Khanna partnership no matter how much he posts on Truth Social.”
Khanna lamented Massie’s primary loss on NBC’s “Meet the Press” last month, telling the outlet that he had been “taken out” because of the pair’s collaboration on opposing the war in Iran and the Epstein Transparency Act.
“Thomas is a real friend. He’s a good man, and he was taken out for two reasons,” Khanna said. “One, he had the courage to go after some very powerful people in working with me to get the Epstein Transparency Act passed. As he mentioned, that’s historic bipartisan legislation that finally got justice for the survivors, and he had people spend millions of dollars, and had the President of the United States after him. And second, he worked with me to stop this war in Iran.”

Hasan Piker blames Israel after UK bars him from entry, citing ‘potential risk’
(JTA) — Leading British Jewish groups are applauding the UK government’s decision to bar the influential anti-Israel streamer Hasan Piker as well as his controversial uncle Cenk Uygur from entering the country.
The British interior ministry revoked Piker’s and Uygur’s travel authorizations on Monday, saying in a statement that “their presence in the UK may not be conducive to the public good.”
The ministry’s statement did not specify its concerns about the men but added that decisions to refuse or cancel ETAs are based “solely on an assessment of the potential risk an individual may pose to UK society.”
The revocations follow advocacy by Jewish groups against Piker’s planned appearance this week at the South by Southwest London festival, where he was due to speak on “How the American Left Learned to Speak the Internet.”
A number of Jewish groups urged the government to block Piker’s entry. The Community Security Trust said that he “has a record of promoting rhetoric that includes antisemitic themes, denial of well documented atrocities and apparent support for extremist groups.” Last week, a lawmaker from the Labour party, David Taylor, publicly called on the Home Office to revoke Piker’s visa.
Piker has also drawn sharp opposition from U.S. Jewish groups in recent months, as he has played an increasingly prominent role in advocating for progressive Democrats. His critics note that he has said he prefers Hamas to Israel and said “I don’t have an issue” with Hezbollah. Hamas and Hezbollah are considered terrorist groups under UK law.
In social media posts, both Piker and Uygur blamed Israel for their being barred from entering the UK.
“I’ve been banned for criticizing Israel. Are we free anymore?” Uygur tweeted, in one of multiple posts making the claim. “This is oppression of Western citizens by our own governments on behalf of a different country!” He later said it was “an honor to have made Israel’s enemies list.”
Piker responded to his uncle’s post on X, saying, “The uk has revoked my visa as well. all at the behest of israel. the west is betraying ‘liberal values’ for a genocidal fascist foreign government. soon we will all become Israel.”
The revocations come as the British government is under extreme pressure to demonstrate strong opposition to antisemitism, following a string of attacks that have unsettled British Jews. In recent weeks, the government has allocated new resources for security in Jewish communities and canceled the travel authorization for Ye, the American musician with a history of antisemitic remarks and a recent single called “Heil Hitler.”
Multiple Jewish leaders said they were pleased that the government had moved to block Piker’s entry.
“The government is right to ban those who seek to spread hatred from entering the UK,” the Jewish Leadership Council’s director of public affairs, Russell Langer, said in a statement. He added, “When Jews are being stabbed on the streets of London and Manchester, we should not be importing more antisemitism into this country.”
The acting president of the Board of Deputies of British Jews, Adrian Cohen, applauded the decision in a statement. “Where there is clear risk of individuals breaking UK laws and stoking community tensions, by showing support for banned terrorist groups or inciting hatred, and where event organisers have failed to show responsibility, it is right that government step in,” he said.
And the CST said that while criticizing Israel can be legitimate, Piker had exceeded the bounds of acceptable discourse.
“There must be consequences when public figures cross into hate speech,” the group said in a statement. “Piker has a record that goes far beyond robust or controversial political speech, including rhetoric that contains antisemitic themes, the denial of well-documented atrocities and language that risks fuelling antisemitism.”
The interior ministry said anyone who has an ETA revoked can apply for a visa, which would afford them a reconsideration.

New York’s Israel Day parade was a shanda — but not because of Mamdani
Mayor Zohran Mamdani made the right decision in skipping the city’s annual Israel Day Parade — because of the specific Israeli officials the parade honored.
American Jews have the right to celebrate Israel’s existence, if they find it to be a meaningful part of their personal Jewish identities. But Mamdani’s specific decision not to march in this specific parade, this year, alongside far-right ministers Bezalel Smotrich, Amichai Chikli and Ofir Sofer, is defensible. Those painting that choice as a sign of antisemitism have a lot of explaining to do about whose company they choose to keep.
Chikli, Israel’s minister of diaspora affairs and combating antisemitism — the man who is supposed to be the voice of diaspora Jews in Israel — has used his platform to spread hatred. He has described LGBTQ+ Pride events as “disgraceful vulgarity”; courted far-right European extremists like Tommy Robinson while parroting their Islamophobic statements; and called antisemitic dog whistles deployed against George Soros by the like of Elon Musk “anything but antisemitism” — while serving as the minister tasked with combating antisemitism.
His behavior has been so outrageous that in 2025, hostage families and Jewish community leaders across Europe signed letters calling him an “inappropriate representative,” citing his statements calling for the expulsion of people from Gaza and southern Lebanon, which they said amounted to support for ethnic cleansing.
Smotrich’s record of inflammatory statements is even more extensive. In 2023, he called for the Palestinian village of Hawara in the West Bank to be destroyed by the state, saying “I think the village of Hawara needs to be wiped out” shortly after a shocking settler attack there that some compared to a pogrom. The United States State Department decried those remarks as “repugnant” and “disgusting.”
Smotrich has since called for Gaza to be emptied of its Palestinian population, and has spearheaded the radical expansion of Israeli settlements in the West Bank, advocating for annexation with the explicit intent of preventing the establishment of a Palestinian state. He himself says the International Criminal Court’s Office of the Prosecutor has reportedly filed a secret arrest warrant application against him for alleged war crimes and crimes against humanity in the occupied West Bank.
At the Sunday parade, Smotrich approvingly told attendees that the event reminded him of the Jerusalem Flag March, an ultra-nationalist procession where participants this year chanted “Death to Arabs” and attacked Palestinian residents.
And Ofir Sofer, Israel’s immigration and absorption minister, has called for changes to Israel’s Law of Return, complaining that many new immigrants to Israel are not Jewish under Orthodox halachic standards. His vision of Israel includes no room for Reform Jews, secular Jews or partial-heritage Jews.
These are the people Mamdani was supposed to join in celebration?
Mamdani did not refuse to celebrate Jewish life. He refused to endorse these deeply problematic Israeli officials by appearing alongside them. That is not a slap in the face to Jewish New Yorkers. It is, if anything, a gesture of respect toward the many Jewish New Yorkers, including me, who find Chikli, Smotrich and Sofer an embarrassment and a threat to the diverse, pluralistic, egalitarian Judaism we actually practice.
Mamdani has stated clearly that he believes Israel has a right to exist, although not as a hierarchy that favors Jewish citizens over others. He has backed his administration’s Office to Combat Antisemitism and proposed expanded funding for hate crime prevention. He guaranteed a robust police presence at the Israel parade, spending weeks planning to ensure it proceeded, in his words, “seamlessly and peacefully” — as it did.
None of this fits the profile of an antisemite.
And those who criticized Mamdani’s refusal to participate are failing to grapple with an important truth: Mamdani’s politics, whatever one thinks of them, are not alien to American Jewish life. They are, instead, increasingly central to it.
A poll by the Jewish Voter Resource Center, released just this week, found that almost half of American Jews under 35 support a binational state: a single country in Israel, the West Bank and Gaza, governed by all its inhabitants together. Among non-Orthodox Jews under 35, that figure reaches 51%.
This is not a fringe position on the left flank of the community. It is a near-majority position among the next generation of American Jews. Add to that the fact that a 2025 survey by Jewish Federations of North America — not a left-wing organization — found that only 37% of American Jews overall identify as Zionist at all, while among young Jews aged 18 to 34, the share identifying as anti-Zionist or non-Zionist has reached nearly a third.
As J Street president Jeremy Ben-Ami put it: “The growing disaffection of younger Jewish Americans from Israel is a direct consequence of the policies of Bibi Netanyahu and the way the American Jewish establishment has demanded an ‘Israel right or wrong’ loyalty.”
When we ask whether Mamdani’s absence alienates Jewish New Yorkers, we need to ask: which Jewish New Yorkers? Did Mamdani marginalize himself from American Jewish life — or did the parade organizers, by welcoming these ministers, marginalize themselves from a large and growing portion of it?
The questions at the heart of this controversy — what Zionism means, whether anti-Zionism is compatible with Jewish solidarity, and how to honor Israeli independence while acknowledging Palestinian catastrophe — are genuine, difficult and deeply contested. I have colleagues I respect on multiple sides. I have family members who would disagree with everything I have written here.
But a parade is the worst possible venue for this conversation. A parade is not a symposium. It is not a town hall. It is a celebration, a statement of solidarity, an embodiment of a particular political position. Attending it is an endorsement of that position. And when the parade features ministers who demean Reform Jews, court European neo-fascists, advocate for the further reduction of Palestinian rights and liberties, and favor restricting who counts as Jewish enough to return to a Jewish state, the act of marching becomes an endorsement of those things, too.
We do need richer, more honest, more nuanced conversations about Zionism, anti-Zionism, Israel, and diaspora Jewish identity. Those conversations are happening, in synagogues, in classrooms and in the pages of Jewish publications like this one. They deserve serious venues and serious interlocutors.
Fifth Avenue on a Sunday afternoon, with Chikli, Bezalel and Sofer as honored guests, is not that venue.
Mamdani was right to decline to issue that endorsement. To the Jewish establishment that has called him an antisemite for it: I would ask you, with all due respect, to look again at who you invited to the party.
