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.

High-Stakes US Special Forces Mission Rescues Airman From Iran After F-15 Crash

US forces staged the audacious rescue of an airman behind enemy lines after Iran downed his fighter jet, officials said on Sunday, resolving a crisis for President Donald Trump as he weighs escalating the war, now in its sixth week.
The airman rescued by special operations forces, who Trump said was a colonel, was the weapons-systems officer on the downed F-15, a US official told Reuters.
“Over the past several hours, the United States Military pulled off one of the most daring Search and Rescue Operations in US History,” Trump said in a statement, adding that the airman was injured but “he will be just fine.”
The officer was the second of two crew members on the warplane that Iran said on Friday had been brought down by its air defenses. Iran’s Revolutionary Guards said several aircraft were destroyed during the US rescue mission, Tasnim news agency reported.
Reuters reported on Friday that the first crew member had been retrieved, triggering a high-profile search by both Iran and the United States for the remaining airman.
Iranian officials had urged citizens to help find him, hoping to gain leverage against Washington in the war Trump and Israel launched on February 28.
Trump has threatened to escalate the conflict in the coming days with attacks on Iran’s energy infrastructure.
Had Iran captured the airman, the ensuing hostage crisis could have shifted American public perception of a conflict that opinion polls show was already unpopular.
Trump said the airman was rescued “in the treacherous mountains of Iran” in what he said was the first time in military memory that two US pilots had been rescued, separately, deep in enemy territory.
The official told Reuters that as the weapons-systems officer was moved from near a mountain to a transport aircraft parked within Iran, US forces had to destroy at least one of the aircraft because it had malfunctioned.
U.S. AIRCRAFT HIT
The rescue effort, involving dozens of military aircraft, encountered fierce resistance from Iran.
Reuters reported on Friday that two Black Hawk helicopters involved in the search were hit by Iranian fire but escaped from Iranian airspace.
Separately, a pilot ejected from an A-10 Warthog fighter aircraft after it was hit over Kuwait and crashed, the officials said, though the extent of crew injuries was unclear.
Still, Trump was triumphant.
“The fact that we were able to pull off both of these operations, without a SINGLE American killed, or even wounded, just proves once again, that we have achieved overwhelming Air Dominance and Superiority over the Iranian skies,” he said in his statement.
US air crews are trained in what to do if they go down behind enemy lines, measures known as Survival, Evasion, Resistance and Escape, but few are fluent in Persian and face a challenge in staying undetected while seeking rescue.
The conflict has killed 13 US military service members, with more than 300 wounded, US Central Command says. No US troops have been taken prisoner by Iran.
While Trump has repeatedly sought to portray the Iranian military as being in tatters, they have repeatedly been able to hit US aircraft.
Reuters reported on US intelligence showing that Iran retains large amounts of missile and drone capability. Until just over a week ago, the US could only determine with certainty that it had destroyed about one-third of Iran’s missile arsenal.
The status of about another third was less clear, but bombings probably damaged, destroyed or buried those missiles in underground tunnels and bunkers, Reuters sources said.
The US and Israeli war on Iran has spread across the Middle East, killing thousands and hitting the global economy with soaring energy prices that are fueling fears of inflation.

On Easter, Pope Leo Urges World Leaders to End Wars, Renounce Conquest

Pope Leo urged global leaders in his Easter message on Sunday to end the conflicts raging across the world and abandon any schemes for power, conquest or domination.
The pope, who has emerged as an outspoken critic of the Iran war, lamented in a special message to the thousands gathered in St. Peter’s Square that people “are growing accustomed to violence, resigning ourselves to it, and becoming indifferent.”
“Let those who have weapons lay them down!” the first US pope exhorted. “Let those who have the power to unleash wars choose peace!”
Leo did not mention any specific conflicts in the message, known as the “Urbi et Orbi” (to the city and the world) blessing. It was unusually brief and direct.
The pope said that the story of Easter, when the Bible says Jesus rose from the dead three days after not resisting his execution by crucifixion, shows that Christ was “entirely nonviolent.”
“On this day of celebration, let us abandon every desire for conflict, domination, and power, and implore the Lord to grant his peace to a world ravaged by wars,” Leo urged.
Leo, who is known for choosing his words carefully, has been forcefully decrying the world’s violent conflicts in recent weeks and ramping up his criticism of the Iran war.
In a sermon for the Easter vigil on Saturday night, he urged people not to feel numbed by the scope of the conflicts raging across the world but to work for peace.
The pope made a rare direct appeal to US President Donald Trump on Tuesday, urging him to find an “off-ramp” to end the Iran war.
In his address from the balcony of St. Peter’s Basilica on Sunday to the Square below, decorated with thousands of brightly colored flowers for the holiday, Leo offered brief Easter greetings in ten languages, including Latin, Arabic and Chinese.
The pope also announced he would return to the Basilica on April 11 to host a prayer vigil for peace.

Temple Mount Set for Limited Reopening to Jews and Muslims

i24 News – Israeli authorities are preparing to partially reopen the Temple Mount in Jerusalem to both Jewish and Muslim worshipers for the first time since the start of the war with Iran, under a tightly controlled and highly restricted security arrangement, i24NEWS has learned.
According to details obtained by i24NEWS, the Israeli police, backed by National Security Minister Itamar Ben-Gvir, are also expected to permit limited access for Jewish worshipers to the Western Wall as part of the same phased plan.
Under the framework, access to the Temple Mount and surrounding holy sites would be restricted to small groups of up to 150 people at a time. In the event of a missile alert, all visitors would be immediately evacuated in accordance with emergency protocols.
The decision follows a recent Supreme Court ruling allowing demonstrations in a limited format. Police argue that a consistent standard must apply across both civic gatherings and religious sites, with Ben-Gvir insisting that “there cannot be one rule for demonstrations and another for the Temple Mount.”
However, the reopening contradicts recommendations from the Home Front Command, which has advised keeping sensitive sites closed due to the ongoing risk of missile attacks.
Israeli Justice Minister Yariv Levin has proposed transferring authority over such security-related decisions exclusively to defense officials, an initiative that could reshape the balance between the judiciary and security establishment regarding restrictions on public access.
