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.

Talarico blames Netanyahu, not the Israeli people, for devastation in Gaza
(JTA) — James Talarico, Texas’ Democratic nominee for the U.S. Senate, said he holds Prime Minister Benjamin Netanyahu, rather than the Israeli people, responsible for civilian devastation in Gaza.
Talarico, a Texas state representative, is running neck and neck against Republican Attorney General Ken Paxton, in a race whose results could affect which party controls the Senate this November. Israel has been one of many sources of disagreement among the candidates, who have sparred on issues ranging from affordability to immigration to reproductive rights.
“I believe that Israel, like any nation, has a right to defend its people,” the candidate said while fielding questions on Wednesday at a CNN town hall. “But I don’t believe that Benjamin Netanyahu has a right to wage war against civilians or use collective punishment or restrict aid to civilians.”
A Texas Politics Project poll, issued by the University of Texas this week, showed Paxton trailing Talarico by 3 percentage points, with 47% to the Democrat’s 50% and a margin of error of 3.34 percentage points.
Talarico said in August that he supported stopping arms sales to the Netanyahu government and conditioning military aid “on ending the death and the destruction in Gaza and the West Bank.” He declined to call the crisis “genocide,” noting that the term is being litigated in the International Court of Justice. But he said he’d “use every bit of our nation’s diplomatic and financial leverage to protect the lives of Palestinians.”
When he was pressed further by Rabbi Holly Levin Cohn of Congregation Beth El Binah in Dallas during the town hall, Talarico stressed the importance of directing his criticisms “toward Prime Minister Benjamin Netanyahu and not the Israeli people.”
Addressing Israelis’ trauma, Talarico acknowledged that the Oct. 7, 2023, Hamas attack on Israel “was the deadliest day for the Jewish people since the Holocaust.”
Cohn pushed back on his comments regarding aid restrictions, noting Israeli support of humanitarian efforts and arguing that there’s much more going on in the country than the media may be projecting.
Talarico told the rabbi he recognized that his “words carry weight” and gave her his word that he’s “going to continue to listen to all sides of this conflict.” He also expressed hope that “we can all come together to fight for a two-state solution where we have security for Israel and we have freedom and self-determination for Palestinians.”
Talarico also gave a “shoutout” to a local rabbi, Neil Blumofe at Congregation Agudas Achim in Austin. “I spent my first year of my seminary studies learning the Hebrew scriptures from a local rabbi,” he said. “Shout out Rabbi Neil Blumofe!” Cohn grinned.

Irish Jewish leader ‘shocked’ after hotel cancels over 70 rooms for antisemitism conference
(JTA) — DUBLIN — An Irish Jewish leader said a Dublin hotel canceled rooms reserved for European delegates after learning that they were visiting for an antisemitism conference.
Maurice Cohen, the president of the Jewish Representative Council of Ireland, said he booked over 70 rooms at the Herbert Park Hotel for people attending a meeting of the Special Envoys and Coordinators Combating Antisemitism (SECCA).
The envoys, who included Jewish community leaders, diplomats and government ministers from across Europe, were invited to the conference this week organized by the World Jewish Congress and the European Commission. The event was tied to Ireland’s Presidency of the Council of the European Union, which rotates between EU member states, and included delegates meeting with Irish Prime Minister Micheál Martin. Most of the government-appointed special envoys are not themselves Jewish.
Cohen said he met with Herbert Park Hotel’s general manager in May to inspect its conference rooms and explained the purpose of the event. According to Cohen, the manager responded by asking, “Will the IDF be involved?”
That question “shocked” Cohen, he told the Jewish Telegraphic Agency.
“I said, this is about antisemitism. It’s not about Israelis, it’s not about Israel, it’s not about the IDF,” he said.
Cohen said the manager told him she had to consult with the hotel owners to determine if his booking could be accepted. The next day, he learned that the rooms were canceled without explanation. The Herbert Park Hotel did not respond to JTA requests for comment.
Cohen booked rooms for the delegates and the conference at different hotels. He described the cancellation in a speech at the SECCA meeting on Tuesday, calling it an example of “contemporary antisemitism.”
“How quickly does the word ‘Jewish’ change a conversation?” he said to the attendees. “How easily does a gathering about antisemitism become associated with the Israeli army? And how quickly can people who were welcome when they were simply 70 hotel guests become something rather different once they are known to be attending a Jewish conference?”
Yoni Wieder, Ireland’s chief rabbi, suggested that the hotel could have based its decision on fears of controversy.
“It’s possible that whoever took the decision had no objection to the conference itself,” Wieder told JTA. “They may simply have wanted to avoid the possibility of protests outside the hotel or some other backlash.”
Ireland’s government has been sharply critical of Israel. The country has recognized Palestinian statehood, barred Israeli far-right ministers from entering its borders and in July passed a law that banned imports from Israeli settlements in the Palestinian territories. Martin has said that Israel committed genocide in Gaza, a charge Israel vigorously rejects. He has also condemned rising antisemitism in Ireland, which is home to about 2,200 Jews.
Herbert Park Hotel is “actually quite familiar with Jewish guests,” according to Wieder, who said that he has overseen kosher catering at the hotel.
Cohen, who has lived in Dublin all his life, said he had fond memories of the hotel. For years it was his favored site for meetings, New Year’s Eve celebrations and his mother’s birthdays through her 93rd.
“Over time the hotel became associated in my mind with friendship, celebration and my mother,” he said in his speech. “So it was strange that, many years later, the same hotel would acquire a very different place in my memory.”

Whatever you think of Ilhan Omar, these threats are unconscionable
The Trump administration is reportedly planning to build a case to strip Congresswoman Ilhan Omar (D-MN) of her citizenship and eventually deport her.
It is my hope that American Jews — even those who do not like Omar and can recite every questionable comment she has made over the past 15 years to illustrate why — will understand this as offensive and outrageous not only because they are Americans, but because they are Jews.
The Trump administration may claim that it is building a case against Omar due to paperwork (reports suggest that they are interested in whether her father listed her age as 17 on her citizenship application when she was really 18). It is similarly filing dozens of lawsuits attempting to denaturalize citizens by trying to prove they lied in the process of gaining citizenship. However, that this is happening now, ahead of the midterm elections against a sitting member of Congress, a high-profile progressive whom the president has said should “go back” to her country of origin, suggests that it is, to put it mildly, politically motivated.

Evidently, the Trump administration sees citizenship not as a right or a responsibility but as a reward, one that can be taken away if that is seen as useful to the president and his adherents. That use could be silencing political opposition or something as simple (and callous) as an opportunity to brag about the sheer number of attempted denaturalizations.
Jews, too, have found themselves on the wrong end of political denaturalization. I do not mean to compare the Trump administration to the Nazis, but the stubborn fact is that Jews were indeed stripped of their citizenship as part of a political project in Germany and elsewhere in Europe in the 1930s and 40s. And in the early 20th century in the United States, it was Jews who politicians claimed were incapable of assimilating, of ever really being a part of the United States. These arguments culminated in legislation that kept out Jews who could have found refuge here. The threat of denaturalization and the experience of perpetual otherness is a grievous part of modern Jewish history; we should be offended by its presence in our political present.
Jewish tradition as well as history encourages us to stand up to authority when that authority is wrong. Mordecai refuses to bow to Haman; Nathan yells at King David for sleeping with Bathsheba and having her husband killed; Moses famously urges Pharoah to change his oppressive ways. Even God is on the receiving end of pushback when Abraham pleads and negotiates to spare Sodom.
I do not think one needs to be Jewish to be outraged by the attempt to denaturalize Ilhan Omar. I think it is also bone-chilling as an American who believes we, including our elected officials, have the right to openly oppose our president, and I am worried as a person who thinks it would be good to continue to live in a democratic republic. And I am sure that there are Jews who will say that Omar deserves to lose her citizenship because she has said things about Israel they do not like.
But the Jewish lens through which I see this is that it is right to challenge power when it is abused, and it is wrong for the powerful to make a show of trying to cast their opponents out of the country.
The point is not whether Trump can make good on the threat to strip Omar of her citizenship and deport her, but that it is obscene to use denaturalization as punishment for being a high-profile political opponent in the first place. If he is trying to make it more dangerous to speak out while being from the “wrong” country, then the rest of us need to say that this is a fundamental misunderstanding of what it means to be an American citizen.
We should do this because we are Americans and we should do this because we are Jews. We should do this because of the ways in which our American and Jewish identities bleed into one another. And, we should do this because we may not know exactly whether it is as Americans or as Jews that we know we have to protect the right to speak truth to power, but we know we need to do it all the same.
