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.

Rep. Dan Goldman urges ‘no’ vote on proposed Brooklyn Israel boycott, warning of antisemitism
Rep. Dan Goldman of New York and his primary challenger Brad Lander are wading into the contentious debate over a proposed boycott of Israeli products at a Brooklyn cooperative grocery store ahead of an expected vote next week.
In a statement shared exclusively with the Forward on Wednesday, Goldman urged members of the popular Park Slope Food Coop in Brooklyn to attend a May 26 vote and cast ballots against the boycott resolution — and condemned the measure as antisemitic.
“Everyone is free to criticize the Israeli government — which I do not hesitate to do — but joining a movement that was founded on the principle of the elimination of Israel will have no impact on the Israeli government or the Israeli economy,” Goldman said in his statement. “Instead, it only succeeds at shifting the responsibility for the Israeli government’s actions to American Jews — which is quintessential antisemitism.”
Goldman said that he is aligning himself with Rabbi Rachel Timoner of Congregation Beth Elohim, a progressive leader, as the debate has spilled into local politics and Jewish communal life in the progressive neighborhood.
The resolution says the boycott would persist “Until Israel complies with international law, including by ceasing unlawful discriminatory practices, in its treatment of Palestinians.”
Timoner addressed the proposal in her weekly Shabbat sermon earlier this month.
“Many simply want to see the Palestinian people be free and safe and equal, and I do too, but this is not the way,” Timoner said. “This way is wrong.
Calling it a “proxy war” to what has been dividing Americans in recent years over the Israeli-Palestinian conflict, one “that is laced with antisemitism, Timoner said that many members of her congregation — she and herself — would be forced to resign from their co-op membership if the resolution passes.
The rabbi’s sermon reflected the careful line she has tried to walk since the Oct. 7, 2023 Hamas attack and the war in Gaza — openly criticizing Israeli government policies while rejecting the singling out of Israel. In March 2024, Timoner attended for the first time what was then a weekly protest to call for a bilateral ceasefire and hostage deal, one that Lander attended regularly. In her remarks she said that she had held back until then from calling for a ceasefire in Gaza “because it was being used by people who celebrated Oct. 7, people who do not hold Hamas responsible, and people who want to eliminate the state of Israel — and I did not want to be associated with that.”
Timoner is a co-founder and board member of the New York Jewish Agenda, a progressive advocacy group formed in 2020 to be a voice for liberal Jews in New York. Lander is a member of NYJA’s leaders network. A Goldman campaign official noted that the congressman and Timoner have met several times privately to discuss issues affecting the district and that Goldman has attended services at Beth Elohim in the past.
Goldman, the two-term incumbent, challenged his Democratic primary rival to publicly oppose the measure as well, “to stand with our neighbors, and make it clear that this dangerous bigotry has no place in our city.”
Lander, a close ally of New York City Mayor Zohran Mamdani, told the Forward he isn’t a member of the Coop but would vote against the resolution if he were, pointing to Timoner’s sermon. “Principled people can disagree here,” Lander said in a statement that did not take a position on the resolution. “Boycotts, divestments, and sanctions are legitimate tools of advocacy campaigns. Unlike my opponent, I don’t believe all opposition to Israel is antisemitic.”
A long-running boycott fight
The proposal to boycott Israeli products has riven the Brooklyn institution’s roughly 16,000 members. It was introduced in 2024 by a local advocacy group called Park Slope Food Coop Members for Palestine. The resolution would require the Coop to boycott Israeli-made products “until Israel complies with international law in its treatment of Palestinians.”
Coop4Unity, opposing the resolution, is urging shoppers to “bring back cooperation” and “stop polarization.”
The measure is largely symbolic, given that the Coop only carries a handful of items imported from Israel, like EcoLove shampoo and conditioner. At least one, Al Arz tahini, is made by an Israeli Arab in Nazareth. The coop first considered a boycott resolution in 2012.
The debate has grown increasingly heated in recent months, erupting most recently publicly during a general meeting when a member made said “Jewish supremacism is a problem in this country,” a remark that many attendees and Jewish organizations condemned.
The comment — which received applause at the meeting — came during a second resolution that would lower the voting threshold for boycott measures from 75% to 51%.
Goldman strongly condemned the remarks in his statement on Wednesday. “That is not a critique of Israeli policy or advocacy for Palestinian rights,” he said. “It is an old and ugly antisemitic conspiracy theory that fueled the Nazis and then was used by David Duke and the Ku Klux Klan.”
A heated primary over support for Israel
The boycott fight is the latest issue in an already heated primary challenge to Goldman being largely battled over Israel and antisemitism.
Last month, Lander, who has described himself as a liberal Zionist, joined some progressive House members in calling for an end to U.S. aid to Israel. Lander — who described Israel’s actions in Gaza as “genocide” — said he would apply that as well to Israel’s defensive Iron Dome system, high-tech missile interception that protects lives, property and infrastructure against assaults from Iran and allied groups, including Hamas and Hezbollah. Lander said that Israel has the ability to purchase its defense with its own funds.
The 10th Congressional District, which includes Borough Park and Park Slope in Brooklyn as well as parts of lower Manhattan, voted heavily for Mamdani, an outspoken critic of Israel. Mamdani is backing Lander in the primary.
Goldman, an heir to the Levi Strauss fortune and former Trump impeachment prosecutor who was elected in 2022, is aligned with the mainstream positions of national Democrats on Israel: supportive of Israel’s security while finding a pathway for a two-state solution, sharply critical of Prime Minister Benjamin Netanyahu’s right-wing government, and opposed to settlement expansion and settler violence.
Recent polling has shown Goldman trailing Lander in the June 23 primary.
Goldman framed the Coop dispute as about something larger than electoral politics. “It’s time we unite together on this issue,” he said, “and fight for the safe, loving, inclusive community we all deserve.”

Itamar Ben-Gvir draws criticism from Netanyahu for video taunting detained flotilla activists
(JTA) — Prime Minister Benjamin Netanyahu has joined a chorus of Israelis and Jews denouncing his national security minister, Itamar Ben-Gvir, for posting a video that showed Ben-Gvir taunting detained activists from a Gaza-bound aid flotilla that had been intercepted by the Israeli navy.
“Welcome to Israel, we are the masters,” Ben-Gvir said in the video as he waved a large Israeli flag above the detained activists, who could be seen blindfolded and kneeling on the ground with their hands behind their backs.
Roughly 430 activists that took part in the Global Sumud Flotilla, which set sail from Turkey last Thursday, were brought to the city of Ashdod aboard Israeli naval ships on Wednesday, marking the latest in a long-running series of confrontations between Israel and activists seeking to break its naval blockade of Gaza.
In a second video posted on social media, Ben-Gvir said that the activists “came here all full of pride like big heroes. Look at them now,” appealing to Netanyahu to grant him permission to imprison them.

Netanyahu said in a statement that he had instructed authorities to deport the activists “as soon as possible.” But he also offered a public rebuke of Ben-Gvir.
“Israel has every right to prevent provocative flotillas of Hamas terrorist supporters from entering our territorial waters and reaching Gaza,” Netanyahu said. “However, the way that Minister Ben Gvir dealt with the flotilla activists is not in line with Israel’s values and norms.”
The foreign ministers of several countries, including Canada, Spain, France, the Netherlands and Italy, also condemned the videos and summoned their Israeli diplomats to answer for the display.
But some of the sharpest criticism came from within Israel, where Ben-Gvir plays a crucial role in maintaining the governing coalition while also engaging in antics that threaten to flare tensions and undercut the country’s claims that it behaves in accordance with international law.
Ben-Gvir is “not the face of Israel,” tweeted Foreign Minister Gideon Saar in English.
“You knowingly caused harm to our State in this disgraceful display — and not for the first time,” Saar wrote. “You have undone tremendous, professional, and successful efforts made by so many people — from IDF soldiers to Foreign Ministry staff and many others.”
Ben-Gvir’s videos come as his antics and rhetoric have drawn new scrutiny in recent days. Last week, he departed from longstanding norms and waved an Israeli flag on the Temple Mount, a Muslim holy site, in a show of Jewish supremacy. His oversight of Israeli prisons, where he has said he wants to see prisoners given only the minimum of food and comfort as required by law, also drew attention because of a New York Times column alleging sexual abuse of Palestinian prisoners.
Progressive groups heavily criticized Ben-Gvir’s video, saying that it was inappropriate for him to be part of the Israeli government.
“The disgusting images of Israel’s National Security Minister abusing detainees from the Gaza flotilla are not just bad optics,” tweeted Mickey Gitzin, the acting CEO of the New Israel Fund. “A government that gives a Kahanist this kind of power has already abandoned any notion of decency. These grotesque images are the real face of current Israeli policy.”
Ben-Gvir’s videos showing the treatment of participants in the latest flotilla offered a contrast to other recent interceptions in which Israel has released footage appearing to show activists being treated without force. When past arrestees from flotillas have alleged abusive treatment, Israel has denied it.
The organizers of the Global Sumud Flotilla said all of its boats had been intercepted by Israel by Tuesday evening, accusing Israel of employing “illegal, high-seas aggression.” The Israeli Foreign Ministry said no live munition was used during the operation, which it said was necessary because it will “not permit any breach of the lawful naval blockade on Gaza.”
Among the activists aboard the more than 50 boats in the flotilla was the sister of Irish President Catherine Connolly. On Tuesday, Connolly, who was elected in October and has a record of anti-Israel rhetoric, called the detention of Irish activists aboard the flotilla “unacceptable.”

What Tuesday’s primaries tell us about Democrats, Republicans and the Israel issue
(JTA) — Reading the polls and listening to conservative podcasts, you would understandably think that Republicans are souring on Israel and poised to start voting like Democrats on the issue. At least a little. But the congressional primary results Tuesday in Philadelphia and northern Kentucky tell a more nuanced story (at least for now).
Chris Rabb’s win in the Democratic primary for a congressional seat representing sections of Philadelphia reinforced the view that staunch anti-Israelism is arguably the most potent force in Democratic politics today. The Pennsylvania state representative executed the progressive playbook perfected by New York City Mayor Zohran Mamdani, showing how tough talk on Israel and AIPAC can galvanize the party’s left-wing base.
In Mamdani’s case, however, he was running against several candidates with strong pro-Israel records and deep pro-Israel support – for a position that has long served as a key public cheerleader for Israel in the United States. Rabb, on the other hand, proved that the strategy can be the winning ticket in a race ostensibly having nothing to do with Israel or AIPAC.
Unlike the New York mayor’s race, Tuesday’s primary in Philadelphia consisted of candidates with similar views on affordability issues, while Rabb’s opponents weren’t exactly waiving the pro-Israel flag or raking in major pro-Israel dollars. But, to borrow from 1964 GOP presidential candidate Barry Goldwater, for an increasing swath of Democratic voters (and D.C. lawmakers), when it comes to standing up for the Palestinians and rejecting U.S. support for Israel, extremism is no vice and moderation is no virtue.
On the Republican side, U.S. Rep. Thomas Massie’s flameout in the GOP race for Kentucky’s 4th District suggests that while there may be a gathering storm of discontent over Israel, the main force that matters when it comes to the ballot box remains Donald J. Trump.
Massie tried his best to make his race a referendum on Israel and the influence of pro-Israel money, rather than Trump’s decision to go all in for challenger Ed Gallrein. It didn’t work.
“I’m walking to an airplane to rejoin the most expensive congressional race in U.S. history. It’s turned into a referendum on whether Israel gets to buy seats in Congress,” Massie said a few days before an election that saw record spending by groups both supportive and critical of the Jewish state. After Massie’s defeat, he quipped: “I would have come out sooner but I had to call my opponent to concede and it took a while to find Ed Gallrein in Tel Aviv.”
Despite such rhetoric, the biggest reason Massie will be leaving Congress in January is that Trump wanted him gone – in part over his criticism of the Iran war, but more generally over a range of issues that the Kentucky lawmaker has broken with Trump on. A string of other Republican primary results suggest that the first rule of GOP politics is: If Trump wants you out, you’re cooked – even without a dollar of pro-Israel money going to your opponent.
In his concession speech, Massie lamented that most GOP voters seem to want somebody who will “go along to get along.” But, he added, one group – young voters – stayed with him.
Unfortunately for Massie, the GOP for the time being belongs to Trump and his loyal followers, not the growing number of young conservatives who want an end to U.S. support for Israel. On the bright side for Massie and his fans, they already hold the power in at least one key area. As one popular pro-Trump conservative social media poster put it: “Don’t think of it as losing a Congressman. Think of it as gaining a podcaster.”
