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.

The stories of Passover and Pittsburgh share a common humanity
At the heart of the Passover story is an act of courage that feels both ancient and urgent.
Before the plagues, before the parting of the Red Sea, a man named Moses made a brave choice. Saved and raised by the Pharaoh’s daughter, he could have looked away from the suffering of others. But instead, Moses recognized his connection to and the humanity of the Israelites, insisting that Pharaoh let his people go.
We often tell the Passover story as one of liberation, and it is. But it is also a story about the risk of crossing divides in society and the tension between extending an open hand or isolating yourself.
That tension is not confined to ancient Egypt: it persists within the Jewish community today. In the wake of the 2018 Pittsburgh synagogue shooting, much of the conversation understandably focused on security, accountability and the urgent need to confront antisemitism directly. The intensity and urgency of that conversation has only increased as Jewish Americans face more hate than ever in our post-Oct. 7 reality. Security and accountability are essential. But on its own, hardening our institutions is not enough. We must also engage in the hard work of educating and building connections across lines of difference.
Hate festers in the absence of relationships across those boundaries, and confronting it requires human connection. When we build compassionate, healthy communities, we begin to heal the persistent societal wounds, such as antisemitism and hatred, that divide us.
In the days and weeks following the attack in Pittsburgh, something remarkable happened: communities that could have remained distant instead drew closer. Muslim neighbors raised money to help cover the cost of funerals and Christian congregations opened their doors, providing the Tree of Life Congregation a safe place for worship services and to gather in community. In those dark days, Pittsburghers, and people from near and far, prayed, cried and raised their voices in song together. They modeled a response to hate rooted in shared humanity.
Passover asks something similar of us. Each year at the Seder table, we are instructed not simply to retell the story but to see ourselves within it, to remember what it felt like to be strangers in a strange land. The Passover Haggadah commands us to welcome the stranger as we were once strangers in the land of Egypt.
The story is a call to action, asking us to recognize the common roots that unite us all. If we are to truly embrace the stranger, then our work must extend beyond our own community and bring people of different backgrounds together to cultivate mutual understanding and learn more about our neighbors. That mandate guides our work at The Tree of Life. We are building a new institution rooted in Pittsburgh with national impact, dedicated to inspiring courageous action and creating compassionate communities. We are bringing people together to engage with one another and to stay connected even when it is hard.
Our programs focus on inquiry, connection, and community engagement, remembering our past and celebrating Jewish tradition and joy. For example, the Holocaust Center of Pittsburgh, one of our core programs, worked closely with Lily Sassani, a local Girl Scout, to develop a Holocaust Education patch, which is now available to all Girl Scouts. The LIGHT Education Initiative, our cornerstone education program, hosts the Eradicate Hate Student Summit, which in 2025 brought together 450 attendees and, with the support of the Grable Foundation and Benedum Foundation, offered $1,000 grants to 34 schools in southwestern Pennsylvania to design and deliver programming on their campuses.
We’re also sharing the story of what happened on Oct. 27, 2018, the history of antisemitism in America and our work to uproot hate in a traveling exhibition visiting communities across the country, beginning in Pittsburgh and next headed to Broward County, Florida, home to Parkland, another community sadly shaped by tragedy. The exhibition offers a peek into what we will be doing in Pittsburgh at the site of the deadliest antisemitic attack in United States history.
Empathy and understanding are powerful antidotes to hate. Developing both is slow, but important. Beloved Squirrel Hill resident Mr. Rogers knew this and exemplified it. He famously responded to racist ideas of his time, not through loud condemnation but by modeling a different way forward. Amid contentious debates over segregated pools, he invited a Black character, Officer Clemmons, to join him in cooling his feet in a small wading pool and sharing a towel. He didn’t argue; he demonstrated.
We are not naive, nor do we think there is a single answer to the challenges and divisions we all face. What we do know, however, is that at the same time that antisemitism has increased exponentially in recent years, divides are deepening and isolation is rising. Pew Research suggests that approximately eight in ten Americans say they cannot even trust people of different political opinions to agree on basic facts.
When antisemitism is rising and trust is waning, the instinct is often to pull back; to ignore the forces of good at work and hide behind walls. Imagine if Moses had remained in Midian, continuing his exile. Ours would be a very different story.
Instead, Moses stepped out in faith and sought community. For the truth is, liberation is not only about moving past a place of discomfort, grief and hardship. It is about what we choose to build afterward and who we bring along the way. Only by recognizing our common humanity and building bridges across lines of difference can we bring about the better future that the youngest people seated at our Seder tables deserve.

Trump Says US May Exit Iran War Soon, Threatens to Quit NATO

The United States will end its war on Iran fairly soon and could return for “spot hits” if needed, President Donald Trump told Reuters on Wednesday, hours before he was scheduled to make a primetime address to the nation.
Trump also said he would state in the speech, which is due at 9 pm EDT (0100 GMT on Thursday), that he was considering withdrawing the US from the NATO alliance.
Asked when the United States would consider the Iran war over, Trump said: “I can’t tell you exactly … we’re going to be out pretty quickly.”
He was expected to reiterate a two-to-three-week timetable for ending the war in Iran during the address, a White House official later said.
US action had ensured Iran would not have nuclear arms, Trump said: “They won’t have a nuclear weapon because they are incapable of that now, and then I’ll leave, and I’ll take everybody with me, and if we have to, we’ll come back to do spot hits.”
An Iranian official, Mehdi Tabatabai, said in a post on X that an important letter to the American people from Iran‘s President Masoud Pezeshkian would be released “in a few hours.”
TRUMP CONSIDERS QUITTING NATO
Global oil supplies were expected to be hit twice as hard this month as in March, the International Energy Agency said on Wednesday, underlining the urgent need for an end to the conflict Trump began with Israel on Feb. 28.
Trump said separately on social media that Iran had asked for a ceasefire but that he would not consider it until Tehran ceased blocking the Strait of Hormuz, a major fuel shipment route. Iran denied making any such request.
Two security sources from Pakistan, which is mediating in the conflict, earlier told Reuters that Islamabad had proposed a temporary ceasefire to both sides but had not heard back from either.
US Vice President JD Vance communicated with intermediaries from Pakistan about the Iran conflict as recently as Tuesday, a source briefed on the matter told Reuters on Wednesday. At Trump‘s direction, Vance signaled privately that Trump was open to a ceasefire as long as certain US demands were met, including reopening the Strait of Hormuz, the source said.
Trump had signaled on Tuesday he could wind down the war in two to three weeks even without a deal, and scaled up threats to pull the US out of the NATO defense alliance if European states did not help stop Iran threatening the waterway.
In his remarks to Reuters on Wednesday, Trump said he would express his disgust with NATO for what he considers the alliance’s lack of support for US objectives in Iran.
European states took pains to appear unruffled, and France’s junior army minister Alice Rufo said operations by NATO in the Strait of Hormuz would be a breach of international law.
JET FUEL AND DIESEL SHORTAGE
The conflict has spread across the region and caused major energy disruption.
IEA head Fatih Birol said the main issue so far from Iran‘s effective closure of the Strait of Hormuz was the lack of jet fuel and diesel that was already a problem in Asia and would hit Europe in April or May.
The head of European budget airline Ryanair said jet fuel supply to Europe could be disrupted from June if the conflict did not end in the next month, potentially forcing the airline and rivals to consider cancelling summer season flights.
Businesses around the world are struggling, with cosmetics and tea among the latest sectors to report difficulties.
However, global stocks rallied and oil prices fell almost 3% as hopes of a de-escalation fueled the biggest rebound in regional equities in more than three years.
Higher fuel prices are already weighing on US household finances before the November midterm elections, with two-thirds of Americans believing the US should work to exit the Iran war quickly, a Reuters/Ipsos poll found.
TANKER HIT OFF QATAR
Drones hit fuel tanks at Kuwait’s international airport, causing a big blaze, and authorities in Bahrain reported a fire at an undisclosed company facility from an Iranian attack.
Qatar said an oil tanker leased to state-owned QatarEnergy was hit by an Iranian cruise missile in Qatari waters, but that there were no injuries or environmental damage.
An overnight strike hit Shahid Haghani Port, Iran‘s largest passenger terminal, deputy regional governor Ahmad Nafisi told state media, calling it a “criminal” attack on civilian infrastructure.
Iran has fired repeatedly on Gulf countries, some home to US bases, during the conflict, and is using the Strait of Hormuz, a conduit for a fifth of global oil and liquefied natural gas, as a bargaining chip.
Iran‘s Revolutionary Guards have threatened to hit US companies in the region including Microsoft, Google, Apple, Intel, IBM, Tesla, and Boeing, from 8 pm Tehran time (1630 GMT) on Wednesday. Trump has said he was not concerned.
LATEST STRIKES
In Tel Aviv on Wednesday, evening air raid sirens and air defense systems were repeatedly triggered as Iran fired a volley of missiles around an hour before the start of Passover, the Jewish festival of freedom.
Israel’s fire and rescue service said there had been multiple “impacts” in the greater Tel Aviv area. It was not immediately clear if the impacts were caused by missile strikes or debris from missile interceptions.
Shortly after the latest Iranian attack, the Israeli military said in a statement that the Air Force was carrying out strikes on dozens of targets across Tehran.

UK Police Arrest 3 More Men Over Arson Attack on Jewish Community Ambulances

British police said on Wednesday they had arrested three more men in connection with an arson attack on Jewish community ambulances in north London last month.
The ambulances were set on fire on March 23 in what British Prime Minister Keir Starmer described as a “deeply shocking antisemitic arson attack.”
The SITE Intelligence website has said an Iran-aligned multinational militant collective called Islamic Movement of the People of the Right Hand had claimed responsibility for the incident near a synagogue in the Golders Green area of London.
Counter-terrorism officers are heading the investigation, but as yet the incident is not being treated as terrorism.
The Metropolitan Police said the three men, aged 20, 19, and 17, had been arrested at separate addresses in east London on suspicion of conspiracy to commit arson with intent to endanger life.
Two were British nationals, while the third was a dual British-Pakistani national. Last week, detectives detained two British nationals aged in their 40s and later released both on police bail.
“We know concern among the Jewish community remains high, but I hope these arrests show that we are doing everything we can to bring those responsible to justice,” said Commander Helen Flanagan, Head of Counter Terrorism Policing London.
