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.

i24 News – Two Israeli officers were seriously wounded and seven additional soldiers injured in two separate incidents in southern Lebanon, the Israel Defense Forces (IDF) said.
According to the military, the first incident occurred during the morning hours amid an encounter between Israeli forces and armed militants operating in the area.
During the engagement, an anti-tank missile was launched toward deployed troops, which the IDF said was fired by Hezbollah operatives. Two officers were struck in the attack, with one sustaining serious injuries and the second moderately wounded.
A second incident took place overnight in a separate sector of southern Lebanon, when Israeli forces operating in the area came under rocket fire. In that strike, one officer was seriously wounded and six soldiers were moderately injured, the IDF said.
The incidents come amid ongoing cross-border hostilities between Israel and Hezbollah, marked by repeated exchanges of fire and periodic ground confrontations in southern Lebanon.

i24 News – Over 12 US troops have been injured in Iranian attacks on a Saudi air base in the past week, the Associated Press reported on Saturday citing two people who have been briefed on the matter.
On Friday, the Islamic Republic launched six ballistic missiles and 29 drones at Saudi Arabia’s Prince Sultan air base, wounding at least 15 troops, including five seriously, according to the sources who spoke to AP on the condition of anonymity.
US officials initially reported that at least 10 US troops were injured, including two seriously wounded.
The base had come under attack twice earlier this week, including an incident that injured 14 US troops, according to the people who had been briefed on the matter.
Located some 100 kilometers from the Saudi capital of Riyadh, the base is run by the Royal Saudi Air Force, but is also used by US troops.

At CPAC, a Generational Divide Over Republican Support for Israel

When former Congressman Matt Gaetz opened his speech by aligning with a Republican faction “loyal to only one nation,” his message to the Conservative Political Action Conference was clear: It was a veiled swipe at perceived Israeli influence over US politicians, even without naming Israel outright.
A month into the US-Israeli war with Iran, Gaetz’s comments struck a discordant note at the annual CPAC event. They cut against calls for unity and exposed a growing Republican rift largely along generational lines, as younger conservatives increasingly question support for Israel.
That skepticism reflects a broader distrust of military intervention among younger Republicans, fueled in part by conservative figures such as Tucker Carlson, whose allegations of excessive Israeli influence on US policy have drawn accusations that he is stoking antisemitism. Carlson has repeatedly denied accusations of antisemitism.
The Iran war, including Israel’s role in it, emerged as one of the main flashpoints at CPAC, which for decades has served as a central gathering for Republican politicians and activists.
Jack Posobiec, a conservative commentator and online influencer, said age 45 is a dividing line, with the younger cohort more likely to question the party’s steadfast support of Israel.
“People want to paint it off as if it’s antisemitism, but I don’t think that’s what it is,” Posobiec told Reuters. “It’s just a question of: Why? What is the purpose of this relationship? And I hear that a lot from young voters.”
The issue has roiled the Democratic Party in recent weeks, with some lawmakers and primary candidates distancing themselves from the pro-Israel lobbying group AIPAC amid growing unease over Israel’s military actions.
It is now exposing fault lines among Republicans as well, turning off young voters who helped propel Trump to victory in 2024 and potentially complicating the party’s efforts to defend slim majorities in the Senate and House of Representatives heading into November’s midterm elections.
Noah Bundy, 17, and Ryder Gerrald, 18, conservative friends from Georgia attending their first CPAC, said they opposed the war with Iran and questioned whether the military operation put Israel’s interests ahead of America’s.
“I think they totally pushed us into a war with Iran,” Bundy said. “My whole family is military and none of us is really for it.”
“Our younger generation, we don’t like Israel as much compared to the older generation,” said Gerrald. He said he would prefer redirecting US taxpayer dollars toward domestic priorities, rather than spending to bolster Israel’s military.
EVANGELICAL SUPPORT FOR ISRAEL
The party’s pro-Israel stance, however, resonates strongly with evangelicals – a pillar of Trump’s political base – and with older voters like Harry Strine III, an 83-year-old CPAC attendee who was wearing a red “Make America Great Again” hat.
“Israel is God’s people,” Strine said. “The US was founded on the Judeo-Christian belief. I guess I’m a traditionalist.”
On the conference’s opening day, Rev. Franklin Graham said that, by striking Iran to protect Israel, President Donald Trump was like the biblical figure of Esther, a Jewish queen who, according to scripture, was elevated by God to save her people from annihilation in ancient Persia.
“I believe God has raised him up for a time such as this, like Queen Esther,” said Graham, a prominent Christian evangelist, invoking a core evangelical belief that the modern state of Israel represents the fulfillment of biblical prophecy.
But unease over the Iran war and rising gasoline prices has pushed Trump’s approval rating down to 36% – its lowest since his return to the White House – a Reuters/Ipsos poll completed on Monday found. Support among his core base remains strong, however, with 74% of Republicans backing the strikes on Iran.
The debate over Israel coincides with a broader Republican fight over the future of the MAGA movement and who belongs in it. Allegations of antisemitism flared at a December event organized by Turning Point USA, a nonprofit focused on promoting conservative politics. At its first national event since founder Charlie Kirk’s death, commentator Ben Shapiro criticized fellow conservatives for associating with figures like white nationalist streamer Nick Fuentes, who has praised Hitler.
In his CPAC speech on Thursday, Gaetz said he did not agree with Shapiro and other conservative commentators “that we have some sort of near slavish loyalty to a country in a faraway land,” an apparent reference to Israel.
He argued that conservatives needed to allow for disagreements and that “antisemitism isn’t hiding around every corner and in every bush.”
Visitors to the CPAC booth of Generation Zion, a nonprofit group that trains young Christians and Jews to advocate for Israel and to combat antisemitism, could pick up a sticker reading “Tucker Carlson Hates Me,” a rebuke of the commentator’s recent criticism of Christian Zionism and Israel’s alleged sway over U.S. politics.
Gabriel Khuly, a 19-year-old volunteer for the group, said that while the Republican Party has an antisemitism problem, it is driven by a small minority with an outsized voice online.
“The actual anti-Israel, antisemitic wing of the Republican Party, I think, makes itself seem a lot bigger than it really is.”
