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.

New Analysis Questions Legality of Campus BDS Efforts Against Israel

A newly released research paper is raising fresh legal questions about the wave of campus and institutional campaigns calling for divestment from Israel, arguing that such efforts may violate anti-discrimination laws in the United States.
The report, published by Northwestern Law School professor Max M. Schanzenbach and Harvard Law School professor Robert H. Sitkoff, examines the growing push by activists affiliated with the global boycott, divestment, and sanctions movement (BDS), which urges governments, universities, and companies to cut economic ties with Israel in the first step to the Jewish state’s eradication.
According to the paper, divestment campaigns that single out Israeli institutions or businesses could potentially run afoul of state and federal laws that prohibit discrimination based on national origin.
BDS advocates argue that their campaign is a form of political protest designed to pressure Israel to change its policies. The movement, formally launched by anti-Israel activists in the mid-2000s, has called for boycotts of Israeli goods, divestment from companies linked to Israel, and government sanctions.
But the new analysis contends that when governments or public institutions adopt such policies, the underlying legality could be questionable. The authors argue that targeting Israel specifically for economic exclusion could conflict with existing anti-discrimination statutes or state laws aimed at preventing boycotts of Israel.
More than half of US states have enacted legislation limiting participation in BDS-related boycotts or requiring government contractors to certify that they are not boycotting Israel. In some states, including California, laws restrict the awarding of public contracts or funding to organizations that participate in boycotts targeting the country.
The paper also challenges the argument frequently made by BDS supporters that such boycotts are protected under the First Amendment to the US Constitution. While individuals may advocate for boycotts as political speech, the authors argue that institutional policies, particularly those adopted by government bodies or public universities, could still violate anti-discrimination or procurement laws depending on how they are implemented.
The paper raises potential anti-discrimination concerns surrounding divestment campaigns that target Israeli companies. The authors argue that some boycott or divestment proposals could expose universities or public institutions to legal vulnerability if investment decisions are based primarily on a company’s Israeli national origin rather than specific conduct. Under certain US civil rights laws and state policies governing public institutions, actions that single out individuals or entities because of national origin may trigger discrimination claims. The paper suggests that if divestment policies are framed broadly against Israeli businesses as a category, rather than tied to particular corporate activities, institutions implementing them could face legal challenges alleging unequal treatment.
The analysis argues that modern divestment campaigns targeting Israel differ significantly from the anti-apartheid divestment movement against South Africa. The paper contends that while many universities in the 1980s adopted selective restrictions on companies directly tied to South Africa’s apartheid system, often aligned with international sanctions and corporate conduct codes, the current iteration of the BDS campaign against Israel frequently calls for broader exclusions based on a company’s ties to Israel itself, potentially creating legal risks such as national-origin discrimination issues.
Divestment campaigns have become especially prominent in recent years on US college campuses, where student groups have pushed universities to withdraw endowment investments from companies tied to Israel or its military. Critics, however, argue the campaigns unfairly single out the world’s only Jewish state and risk creating discriminatory policies against Israeli businesses or academics.
In the two years following the Hamas-led Oct. 7, 2023, massacre of 1,200 people and kidnapping of 251 hostages throughout southern Israel, campus activists have intensified efforts to implement divestment policies on university campuses. While universities have mostly resisted these efforts, federal lawmakers have advanced legislation to truncate divestment initiatives before they gain traction. For instance, in 2024, Congress introduced “The Protect Economic Freedom Act,” which would render universities that participate in the BDS movement against Israel ineligible for federal funding under Title IV of the Higher Education Act, prohibiting them from receiving federal student aid. The bill would also mandate that colleges and universities submit evidence that they are not participating in commercial boycotts against the Jewish state.

UK Holds Four Men on Suspicion of Iranian Spying on Jewish Sites

British police arrested four men on Friday on suspicion of helping Iran’s intelligence services carry out surveillance of people and locations linked to the Jewish community in London.
Detectives said one of the men was Iranian, while three had dual British-Iranian nationality. The arrests were part of a “long-running investigation,” police added, indicating the men‘s alleged activities pre-dated the US and Israeli bombardment of Iran, which started last Saturday.
British lawmakers and the domestic spy agency MI5 have long warned of threats posed to Britain by Iran. Three Iranians were charged with offenses under Britain’s National Security Act relating to assisting a foreign intelligence service last May.
In a separate investigation last year, police arrested five men, four of them Iranian, over a suspected plot to target specific premises, which British media said was the Israeli embassy. They were later released without charge.
“The Jewish community and the wider public will understandably be concerned by today’s arrests. We continue to monitor the situation closely,” interior minister Shabana Mahmood said on X.
Police said the four detained men were aged between 22 and 55. Six others were also arrested on suspicion of assisting an offender, and police said searches were ongoing.
Speaking about the current Iranian conflict on Thursday, Prime Minister Keir Starmer warned that people would use it to divide the country.
“The government is reaching out to communities across the United Kingdom – Jewish and Muslim alike – making sure communities and places of worship have appropriate, protective security in place,” he told a press conference.
Illustrating the threat from Iran, Britain’s MI5 spy boss said that over two years from 2022-2024, his service and British police had responded to 20 Iran-backed plots to kidnap or kill British nationals or individuals based in Britain who were regarded by Tehran as a threat.
Britain also recorded a 4% rise in antisemitic incidents in 2025, making it the second-worst year on record, a charity said. Two men were killed last October during an attack on a synagogue in the northern English city of Manchester.

Turkey Asks Britain’s MI6 to Step Up Protection of Syria’s Sharaa, Sources Say; Ankara Denies Report

Turkey’s intelligence agency asked its British counterpart MI6 last month to take a larger role in protecting Syrian President Ahmed al-Sharaa after recent assassination plots, according to five people familiar with the matter.
After this story was published, Turkey denied that its intelligence agency MIT had made any such request to MI6.
The request highlights efforts by foreign allies to shore up a country still shaken by sporadic violence 15 months after the overthrow of President Bashar al-Assad, with the US-Israeli war on Iran now rattling the wider region.
Those allies see Sharaa as crucial to preventing a relapse into sectarian fighting or civil war, after 14 years of civil conflict drove millions of refugees abroad and allowed Islamic State to control swathes of Syria.
The militants last month stepped up attacks on military and security personnel across Syria and declared Sharaa, a former rebel, their “number one foe.”
It was unclear what specifically Turkey’s National Intelligence Organization, or MIT, had asked of MI6, or what new role, if any, MI6 had taken up.
The Turkish presidency said in a statement issued by its communications directorate that MIT maintains effective cooperation in the fight against terrorism with the international intelligence community and security units in Syria, but that this story did not reflect the truth.
“Contrary to what is claimed in the report in question, it is not true that MIT has made any request to MI6 regarding the protection of the Syrian President or sought to assume such a role,” it said.
ANXIETY RISES IN SYRIA OVER ISLAMIC STATE
Turkey, Britain, and the US last year threw their backing behind Sharaa to try to reunite and rebuild his country of 26 million. London and Washington have scrapped most sanctions on Syria and on Hayat Tahrir al-Sham (HTS), the Islamist group he once led.
The sources who spoke to Reuters requested anonymity owing to the sensitivity of the matter.
MIT, the Turkish foreign ministry, Britain’s foreign office and Syria’s defense and interior ministries did not comment when contacted ahead of publication.
The sources, including Syrian and foreign officials, all cited rising anxiety over a series of reported Islamic State plots to kill Sharaa.
A Turkish source said that MIT, which has played a key role in helping the new government to establish itself, appealed to MI6 for more support after one such incident last month. A senior Syrian security source said the request came after a “high-risk assassination plot,” adding that MIT, MI6, and Syrian authorities were constantly sharing intelligence.
Details of the plot were unclear.
A separate Western intelligence source briefed on the matter believed Turkey wanted to introduce a Western presence in Damascus to provide something of a buffer between the agencies of Turkey and Israel, currently at loggerheads.
REPORTED ASSASSINATION ATTEMPTS AGAINST SHARAA
Last year, Sharaa and two senior cabinet ministers were targeted by Islamic State in five foiled assassination attempts, according to the UN Office of Counter-Terrorism. In November, Reuters reported that Syrian authorities had foiled two of the attempts.
Describing Sharaa as a “watchdog” of the global anti-Islamic State coalition, the group mounted six attacks on Syrian authorities last month in what it called a “new phase.”
On Thursday, Damascus openly acknowledged for the first time that it coordinates with MIT, saying they had cooperated to foil an Islamic State attack in the capital.
Turkish security sources said MIT had identified a team of three preparing remote bomb attacks, enabling Syrian counterparts to prevent an “imminent assault.”
A US diplomat briefed on the matter said MIT’s request to MI6 had been prompted by the Islamic State resurgence.
The Western intelligence source said the two agencies could intensify joint planning and technical operations, but that no decision had been made on whether to send British personnel to Damascus.
A Syrian security source said a physical British presence would be “highly risky.” They said MI6 had been discussed at a meeting in Damascus on Feb. 26 between a delegation headed by Britain’s special envoy for Syria, Ann Snow, and Syria’s deputy interior minister, Major General Abdulqader Tahan.
Sharaa was a commander of Al Qaeda’s Nusra Front in Syria before cutting ties with the group in 2016, then led a coalition of Islamist rebel factions in late 2024 to topple Assad.
