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.

They want Jewish life without Zionism. Now they’re building the institutions to match.
(JTA) — One year after Jewish Currents editor-at-large Arielle Angel called for “new Jewish institutions” that have no attachment to Israel or Zionism, more than 100 Jews crammed into a Victorian house-turned-event space in central Brooklyn in hopes of creating them.
The event was billed as a bootcamp for people hoping to get fledgling Jewish groups off the ground. Sessions focused on topics like staffing and funding, as well as discussions about who, exactly, is welcome in a space that is “anti-Zionist,” “non-Zionist,” “diasporist” and the like.
Many of the groups represented on Monday were minyans, which host prayer services in locations like people’s apartments or community spaces. They sought practical guidance for building their institutions, but also for defining who to welcome as their ranks expand.
“If we’re doing things right,” Angel said, “many of these small minyans will be synagogues in a few years.”
Esti, 27, who declined to share her last name to maintain privacy, is involved in leading an anti-Zionist minyan in Brooklyn. She said she has heard from “so many” attendees that they were relieved to attend services in a space without an Israeli flag.
“People are like, ‘I never thought I could be in a Jewish space like this, I never thought I’d see queer people leading, I never thought I could be in a Jewish space where they’re saying Free Palestine,’” she said. The minyan averages about 50 attendees at Shabbat services, she said.
Some of the speakers at the workshop detailed how they have refused to compromise their organizations’ politics. One panel led by Rabbi Brant Rosen, who helped found the anti-Zionist synagogue Tzedek Chicago, and Rebecca Vilkomerson, the former director of the anti-Zionist group, Jewish Voice for Peace, focused on the process of setting an organization’s “political boundaries.”
Rosen spoke from his own experience, saying that Tzedek Chicago was presented as “consciously not an inclusive community.”
“In other words, this is what we stand for, it might not be for you, it might not be for everyone, and that’s OK. There are many places out there that you can choose,” he said. Rosen added that potential members were not forced to agree in order to join, but rather that they were faced with the question: “Given that these are our values, is this a community you want to belong to?”
Esti spoke to the Jewish Telegraphic Agency on the sideline of the Urbane Arts Club event, which JTA attended on the condition that attendees’ in-session remarks throughout the day were kept off the record, though panelists’ remarks were all on the record.
Americans’ support for Israel has dropped writ large amid its military campaign in Gaza and the war with Iran. A survey by the Jewish Federations of North America found that 37% of Jewish respondents said they identified as Zionist, while 7% labeled themselves anti-Zionist and another 8% said they were non-Zionist. Another 18% said they weren’t sure, while 30% said none of the labels described them.
According to an AP-NORC poll from earlier this year, support for Israel is a less significant component of younger Jews’ religious identity versus Jews older than 45.
“These groups are starting up because of demand,” Rabbi Alissa Wise told JTA.
Wise is a co-founder of the Jewish Diaspora Movement, the group behind Monday’s bootcamp, which is itself in its beginning stages. She has previously worked for JVPe and in October 2023 founded Rabbis for Ceasefire, which has protested for a Gaza ceasefire and an end to U.S. military aid to Israel.
While JVP “played a pivotal role in building Jewish life outside of Zionism,” Wise said there was still a major gap in religious and cultural Jewish institutions that reject Zionism.
In addition to the represented minyans, which facilitate prayer services, and the havurahs, which offer events such as Shabbat dinners and other holiday celebrations, Angel said some attendees were looking to start projects including summer camps, educational offerings and cultural projects such as theater collectives.
Jen Kaminsky, an attendee who is part of the Buffalo Jewish Collective’s leadership team, told JTA that her organization welcomes “a range of Jews, many of whom have not felt comfortable in legacy Jewish institutions.”
“We say that we welcome anti-Zionists and non-Zionists, and people who are questioning Zionism and people who have a range of relationships to Zionism,” Kaminsky said. “If you are comfortable with the values that we put out, or you’re comfortable being in a room where those values are the dominant values, we welcome you.”
Vilkomerson told the group that there should be an attempt to grow membership by engaging people closer to the center in “left-liberal coalitions,” but without making concessions on left-wing values. She put the concept into New York City political terms, pointing to the political alliance between the anti-Zionist Mayor Zohran Mamdani and the liberal Zionist Brad Lander.
“Brad, as a liberal Zionist, was able to partner with Zohran Mamdani — but Zohran set the terms of the campaign, not Brad,” she said.
Also on Monday, Lissy Romanow — a co-founder of the group IfNotNow, which describes itself as “anti-occupation” — gave a nuts-and-bolts session on the first steps of creating an organization, including how to concisely conceive of a group’s DNA and how to avoid burnout among volunteers.
As groups look to grow and achieve loftier goals like setting up permanent locations and hiring paid staff, one clear obstacle stands in the way: funding.
“There’s only so much money on the Jewish left,” Angel told JTA.
Any anti-Zionist group is highly unlikely to receive funds from one of the country’s many Jewish federations, which often maintain deep ties to Israel.
Three left-wing Jewish donors — Liana Krupp, Deborah Sagner and Kathleen Peratis — spoke on Monday about the limited landscape of funding for Jewish anti-Zionist organizations.
“If we don’t flip liberal Zionists we’re not going to grow, because that’s where the money is,” Peratis said.
Participants on Monday, whose groups are mostly volunteer-run, did not have any illusions about that landscape.
“For now, the goal is to keep doing Shabbat in a sustainable way on a regular basis,” Esti said. But she also shared her long-term vision.
“I think it would be amazing to have a brick-and-mortar shul, a place we could call our definitive home,” she said. “But that’s way, way far down the line.”

After bronze win, judo athlete Raz Hershko tells JTA, ‘I stand for something far bigger than myself.’
(JTA) — Israeli judoka Raz Hershko, one of the country’s top athletes, missed a major opportunity in 2025 when the 12-day war between Israel and Iran closed Israeli airspace, preventing her from traveling to Budapest. Earlier this year, she withdrew from the Tashkent Grand Slam after the Shin Bet ordered the Israeli team to leave Uzbekistan.
But nothing could keep Hershko off the podium this weekend, when she won a bronze medal at the World Judo Championships in Baku, Azerbaijan.
Hershko, 28, burst into tears after winning the bout that secured her medal.
“Representing Israel has always been something that moves me, but at this moment, it carries so much more meaning,” Hershko told JTA. “At the end of the day, I step onto the mat alone, but I feel like I have an entire country behind me.”
Hershko dedicated her victory to the memory of Yonatan Gutin, an Israeli soldier killed on Oct. 7, 2023, as well as his family and the people of Israel.
According to his official memorial page, Gutin, a 20-year-old Israel Defense Forces officer, was killed fighting to rescue civilians during the battle for Kibbutz Be’eri. Judo was a central part of his life. He had trained in the sport for about 14 years and was a member of Israel’s cadet national team. Even during his military service, he occasionally returned to his judo club to coach.
Despite the achievement, Hershko made clear that bronze was not the result she had hoped for.
“I’m pretty disappointed that the day ended with a bronze medal, because I was aiming for gold,” she said. “But now it’s time to look ahead to the next goals.”
Hershko has established herself in recent years as one of the world’s leading judokas and one of Israel’s most prominent athletes. She won an individual silver medal at the 2024 Paris Olympics and a gold medal at the 2024 European Championships. She competes in the women’s heavyweight division.
Her latest achievement came just days after Israel marked the third anniversary of the Oct. 7 Hamas-led attacks, a date that has continued to shape the country’s public life and weigh heavily on its athletes competing abroad.
“Knowing that I was able to give people back home even a few moments of happiness, a smile, a sense of pride — that means so much to me. Especially during the times we’re going through, these are the moments that remind me why I do what I do,” she added.
The judoka said that “everything has felt different since Oct. 7” and that she can’t “disconnect” herself from the Israeli reality.
“Before that, I would go into competitions feeling immense pride in representing my country,” she said. “Today, that pride is even stronger. I’m much more aware of what the flag I wear represents, and of the fact that I stand for something far bigger than myself.”
Hershko, however, has little time to dwell on the medal. She told Channel 13 that she would take two days off before returning to training ahead of another competition next week. Asked by JTA how she has managed to stay hungry and focused after achieving so much, the Israeli athlete said she simply enjoys the journey.
“I really love what I do. I love judo, I love competing, I love the challenges, and I think that’s what keeps me hungry,” she said. “Of course, I’m proud of everything I’ve achieved, but I never feel like I’m done or that there’s nothing left to strive for. At the end of the day, the medals are incredible moments, but the journey is what builds me as an athlete, and I’m still enjoying that journey.”

Jewish school educators cancel trip to Italy after Italian education program required participants to denounce ‘genocide’ in Gaza
(JTA) — Educators from Jewish schools across the U.S. canceled a study trip to Reggio Emilia, Italy, over whether the hosts would require participants to formally distance themselves from Israel’s actions in Gaza and the West Bank.
The controversy has drawn accusations of antisemitism from Jewish educators and from Italian Jewish community leaders. It has also sparked a political dispute in Italy.
In an email sent to participants on Oct. 9, the American organizers, the Paradigm Project, said they canceled the trip because of “antisemitic pressure being placed on the group.” In a Zoom call with the participants, the organizers also cited safety concerns amid the scrutiny of the Jewish school educators’ personal profiles by pro-Palestinian activists who were agitating for the declaration, a participant said.
In a leaked audio recording broadcast Monday evening by Italy’s Tg3 TV news program, the president of the host organization Reggio Children, Maddalena Tedeschi, discussed asking participants to sign declarations distancing themselves from the “occupation of territories and genocide.” The recording is of an Oct. 6 meeting of the city’s early childhood education council.
In an interview with the Jewish Telegraphic Agency, Reggio Children spokesperson Francesca Severini said the request — intended to appease local pro-Palestinian activists — had never become an official participation requirement, but acknowledged that the additional wording had been discussed.
The Paradigm Project, a professional development network for Jewish early childhood educators, organized the trip for 68 Jewish educators. A separate delegation of 22 educators from Israel arrived in Reggio and was participating in the program this week.
“Now, more than ever, we must bring back the light and keep the bridge between us strong,” the Israeli educators said in opening remarks Monday.
Reggio Children, an educational organization partly owned by the municipality, promotes the city’s internationally influential approach to early childhood education and provides training for educators. Reggio Emilia Mayor Marco Massari and the city’s education official Marwa Mahmoud did not respond to requests for comment.
The cancellation, which came in a phone call from Paradigm to Reggio Children on Oct. 7, follows months of tensions in the city, where pro-Palestinian activists had protested the participating schools’ ties to Israel. During the weeks preceding the trip, activist Cosimo Pederzoli had publicly accused some of the schools of supporting the Israeli military.
At the Oct. 6 meeting, Reggio Children presented a charter, titled “For a Democratic and Participatory Education,” asking visiting groups and partners to uphold human rights, oppose discrimination, reject war, and condemn genocide. The charter, which was approved and is now on the organization’s website, also opposes violations of human rights in occupied territories worldwide, without naming Israel or Gaza.
Severini, the spokesperson, said that activists, teachers and parents had pressured Reggio Children and the municipality to take the charter one step further and requiring participants to agree to the statement: “I … hereby declare that I distance myself from the occupation of Gaza and the violation of children’s and human beings’ rights in occupied territories as well as every place in the world.”
Severini said that the wording was included as “material for discussion” in a private WhatsApp group. The American organizers were not in the chat, she said, and subsequently received the wording without the context that it would not, in the end, be official language.
Her account contradicts Reggio Children’s earlier public statements. On Oct. 7, the organization acknowledged that the educators had been asked to explicitly distance themselves from the policies of Israeli Prime Minister Benjamin Netanyahu’s government in response to concerns raised in the city. Mayor Marco Massari also acknowledged the additional commitment in a public statement, which says, “This Charter will be signed by all delegations visiting Reggio Emilia in the coming months and years.”
In an email to parents, leaders of Wilshire Boulevard Temple’s early childhood centers in Los Angeles said seven of their educators had been scheduled to join the trip and expressed support for Paradigm’s decision to cancel.
“Paradigm, on behalf of our educators and dozens of others, rightfully refused and canceled participation in the study tour and conference, due to the refusal to sign and other security considerations,” read the email. “All participants were notified on October 7, 2026.”
Pesha Kletenik, head of Manhattan Day School, had planned to join the trip. “This was one of the most painful experiences I’ve had,” Kletenik told JTA. “I never felt so targeted as a Jew before in my life. I’m an American citizen. I have one passport. I’ve lived here my entire life.”
Kletenik said she had hoped to adapt the Reggio approach to Jewish teaching and practice, including their model Passover seder, because “it aligns so beautifully with Jewish values.”
Steve Freedman, head of Solomon Schechter Day School of Bergen County, New Jersey, said his school withdrew an educator from a separate trip planned for November. In a letter to families, he criticized the demand for a political declaration while affirming the school’s commitment to the Reggio approach.
The council of the Jewish Community of Modena and Reggio Emilia, a single institution based in nearby Modena that serves both cities, condemned efforts to boycott educational and cultural initiatives involving Jews. It described the conflation of diaspora Jews with Israel’s government as antisemitic.
The Reggio Emilia approach, developed after World War II by educator Loris Malaguzzi and local families, places children’s exploration, expression, and participation at the center of early childhood learning. It gained wider international recognition after Newsweek named one of the city’s preschools among the world’s 10 best schools in 1991.
Severini said Reggio Children’s relationships with American Jewish and Israeli educators stretch back roughly three decades. The Israeli liaison first visited in 1996, she said, and educators from Reggio have also traveled to the United States and Israel.
The organization has hosted educators from all over the world, Severini said, including China, Russia, and Iran. She said she knew of no comparable controversy involving other visiting groups, including previous delegations from Jewish schools.
Reggio Children, she said, hoped to continue its dialogue with the American educators. For Manhattan Day School’s Kletenik, the cancellation stood in stark contrast with the educational values that had drawn her to the approach.
“How are we to navigate rejection by the very experts we collectively idealized—the gatekeepers of the sensitive worldviews and teachings we trusted to nurture our most tender children?” she wrote in a message to her school’s board.
