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.

Providence voters pass ballot initiative that could lead to divestment of city funds from Israel
(JTA) — Voters in Providence, Rhode Island, have approved a ballot measure that could result in the city divesting public funds from Israel, according to local media, in a major victory for the Israel boycott movement.
In a major victory for the Israel boycott movement, voters in Providence, Rhode Island, have approved a ballot measure that could result in the city divesting public funds from Israel, according to local media.
With 81 of 82 polling locations partially reported, the Rhode Island Board of Elections tallied 75% voting to approve the measure versus 25% rejecting. Both the Rhode Island Current and the Boston Globe report the measure was approved.
“We are overjoyed that the city of Providence has voted — by more than a 3 to 1 margin — to divest our collective dollars from support for genocide and ethnic cleansing,” Lex Rofeberg, who runs the alternative Jewish engagement network Judaism Unbound and was an organizer with the Providence divestment initiative, told JTA. “This historic moment can serve as an example for other cities around the country hoping to align their investments with their values.”
The ordinance calls for the capital city to refrain from investing in “foreign countries conducting ethnic cleansing, apartheid, illegal military occupation, or genocide.” Though the ballot language does not mention Israel by name, it was heavily supported by local pro-Palestinian groups and opposed by some Jewish and pro-Israel groups.
A representative for the Jewish Alliance of Greater Rhode Island previously told the Jewish Telegraphic Agency that the group would explore legal options to challenge the ballot measure in the event that it passed.
The vote makes Providence the largest municipality yet to vote in favor of some form of Israel divestment, following the lead of Somerville, Massachusetts, whose voters approved a nonbinding divestment measure last year. Providence is home to an estimated 15,000 Jews, or around 7% of its population. Progressive Jewish groups, including the local chapter of Jewish Voice for Peace, were among the ballot measure’s advocates.
The city’s mayor, Brett Smiley, a pro-Israel Democrat who converted to Judaism while in office, lost his primary to a democratic socialist, an early indicator of which way the divestment vote would go.
Activist initiatives to challenge U.S. financial aid to Israel have picked up steam in the years since the Oct. 7, 2023 Hamas attacks and ensuing Gaza war. On the morning of Election Day, President Donald Trump, who described aid to Israel as a political liability, announced the U.S. would end nearly $4 billion in annual military aid to Israel by the end of the year.

Republican Lawler concedes to Democrat Conley in fierce battle for Jewish vote in NYC suburbs
(JTA) — Republican congressman Mike Lawler has conceded to Democratic challenger Cait Conley, a former national security official, after competing fiercely for Jewish voters in the lower Hudson Valley of New York.
Lawler has been a staunchly pro-Israel member since joining Congress in 2023, and was endorsed by the Republican Jewish Coalition and the pro-Israel lobbying group AIPAC.
Conley was endorsed by the pro-Israel group Democratic Majority for Israel, and has said she supports Israel while opposing the Benjamin Netanyahu government.
Lawler, who is Catholic, has deep ties to the district’s large Orthodox Jewish population, and touted their support recently when asked about the neck-and-neck polling.
Both Lawler and Conley have tried tying their opponent to polarizing figures in their respective parties. Lawler has asserted that Conley, a moderate, will not separate herself from the progressive wing of the Democratic Party and particularly New York City Mayor Zohran Mamdani, who has a lower favorability rating outside the city. Conley denounced Mamdani’s statement on the three-year anniversary of the Oct. 7, 2023 attack after Lawler challenged her to do so during a debate.
Conley, meanwhile, has tied Lawler to President Donald Trump, accusing him of being a rubber stamp for Trump’s legislative priorities.

In early LA mayoral results, Karen Bass holds slim lead over Nithya Raman, who sparred with DSA on Israel
Early returns in the Los Angeles mayoral election showed incumbent Karen Bass with a slim lead over Councilmember Nithya Raman, whose comments on Israel became a flashpoint in the race.
The first batch of results — totaling about 500,000 votes — showed Bass leading Raman, 50.8% to 49.2%.
The final outcome may not be known until Wednesday or later, a common occurrence in tight California races due to the preponderance of mail-in ballots. Nearly 90% of California voters did so by mail in the June primary.
But if the primary results are any indication, Bass’ lead may evaporate as more votes are counted.
In the June 2 open primary — a system in which the top two vote-getters from any party advance to a runoff — Raman trailed a Republican, Spencer Pratt, by eight points for second place behind Bass. She won the ensuing batches of mail-in ballots, but did not pass Pratt until June 7. She ultimately surpassed him by more than four percentage points.
Raman, a member of the Democratic Socialists of America, has clashed with the organization — and frustrated many of her Jewish constituents — while trying to strike a balance on Israel. She has called the war in Gaza a genocide, but declined to adopt the Boycott, Divestment and Sanctions platform — a stance that led the DSA to consider expelling her.
Bass, a mainstream Democrat who served six terms in Congress before running for mayor in 2022, entered the race as a historically unpopular incumbent, largely thanks to her response to the 2025 Los Angeles wildfires. Raman endorsed Bass prior to declaring her own candidacy on the last day to enter the race, a move Bass has characterized as a personal betrayal.
The polls swung back and forth in the weeks leading up to the election. Bass, who won most labor endorsements, was leading until September, when one poll sponsored by the Los Angeles Times showed Raman ahead by 11 points with a third of voters still undecided. A follow-up poll by the Times last week showed the two in a dead heat.
Unlike many other DSA candidates up for election across the country on Tuesday, Raman, an urban policy wonk who immigrated to the U.S. from India when she was 6, never made Israel a focal point of her campaign. Instead, she focused more on housing, homelessness and budget policy.
But her membership in the DSA, an interview she granted Hasan Piker during the primary and the genocide comments dogged her anyway, especially among Jewish Angelenos.
Raman, after publicly condemning the DSA’s anti-Israel statements after Oct. 7, sponsored a resolution for a ceasefire and return of hostages in March 2024, disappointing mainstream Jewish groups who called the motion one-sided. Then, during the primary, Raman told Piker she believed the Gaza war was a genocide and that Israel was an apartheid state. She also said she would not seek the endorsement of pro-Israel Democratic party groups as she had in 2024.
Her record on Israel seemed likely to come up when Raman participated in the candidate forum for Jewish voters Sept. 29. But Raman struggled to get through answers about the DSA, Piker and especially genocide and BDS — which she called a “legitimate form of peaceful protest” — leading to loud audience groans. During Bass’ turn on stage, the mayor said she did not support BDS and did not believe the war in Gaza was a genocide.
Mail-in voters historically skew to the left, and the primary vote may offer a preview of the margin Raman might need.
In that election, about 58% of the total votes were tallied election night, when Bass led Raman 36.5% to 21%. Raman got the biggest share of the ensuing ballot batches, beating Bass by about five percentage points.
