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.

Some of Mamdani’s Jewish allies criticize his use of ‘monsters’ to describe AIPAC

(New York Jewish Week) — New York City Mayor Zohran Mamdani on Monday defended his use of the word “monsters” to describe AIPAC at a rally Friday for progressive candidates, as some of his Jewish supporters expressed concern that the term may connote an antisemitic trope.

The war of words came as the American Israel Public Affairs Committee is increasingly a target of the progressive movement — including in acts of attempted violence — and as progressive Jews have accused some Israeli right-wing figures of dehumanizing liberal pro-Israel lobbying groups.

“Calling AIPAC and its backers ‘monsters’ casts them as less than human, rather than as human beings who are one’s political opponents,” Rabbi Jill Jacobs, head of the progressive rabbinic human rights group T’ruah, wrote in a Substack post Monday.

“I was taken aback,” Rabbi Misha Shulman, a Mamdani supporter who leads the progressive Brooklyn synagogue The New Shul, told the Jewish Telegraphic Agency about the mayor’s comments. “I didn’t like those remarks. It was a little bit of a flag for me.”

At a press conference, Mamdani said he had been quoting Italian anti-fascist philosopher Antonio Gramsci, whose quote ending “Now is the time of monsters” the mayor had cited at the top of his speech. The rally was intended to boost the mayor’s preferred progressive candidates, including Jewish congressional candidate Brad Lander, ahead of New York’s closely watched Tuesday primaries.

“I used the term to describe all those who are preventing the birth of a new world,” Mamdani told a reporter who asked about the word. He continued, “My use of the term is a broad use that speaks to the untenable nature of a status quo that is quite literally starving people in this city, all in the name of sustaining something that we simply cannot defend any longer.” He did not explain how he saw AIPAC as connected to poverty in New York.

Mamdani insisted he was referring to “not solely AIPAC,” but he singled out the organization again in his Monday remarks to reporters, saying the lobbying group was backing “a status quo for immorality.”

During the rally last week, Mamdani had stated that Gramsci’s “monsters take many forms today,” including “AIPAC, for whom the only thing more frightening than democracy being allowed to run its course is an end to genocide and [Israeli Prime Minister Benjamin] Netanyahu’s wars.” He added that AIPAC’s “goal” is “to turn us against one another.”

For some of the progressive Jews who have supported the mayor, his comments sounded alarms about the use of dehumanizing or sinister rhetoric to describe Jewish groups.

But Shulman said it was actually Mamdani’s remarks in the same speech painting AIPAC as a “dark money” group that was most alarming to him. AIPAC, a lobbying organization that also operates a political spending arm, does not conceal its donors, unlike the traditional profile of a so-called “dark money” campaign finance operation.

“For me, the question of dark money was the tougher knot,” Shulman said, calling Mamdani’s remarks a “tactical mistake.” In the context of rising antisemitism, he added, “For a left-wing leader to use that phrase, and invite traditional antisemitism into this conversation in that way, was not smart.”

Shulman is a member of Israelis For Peace, a New York-based ad-hoc group of progressive Israelis who broadly back Mamdani. While not speaking on behalf of the group, he told JTA their internal group chat lit up with debates over the appropriateness of Mamdani’s speech.

Jacobs of T’ruah said Mamdani’s remarks were part of what she described as a “disturbing trend” of recent left-wing attacks on the lobbying group, including Maine Democratic U.S. Senate nominee Graham Platner accusing his GOP opponent of being “bought and paid for by Benjamin Netanyahu” because of AIPAC’s donations to her campaign.

Rep. Ro Khanna, a California Democrat who has aspirations of higher office, also recently became the first sitting member of Congress to sign a pledge from Track AIPAC, a purported AIPAC watchdog that also targets donations from more liberal pro-Israel groups, including J Street.

Over the weekend, a cafe posted on Instagram that it had rejected a payment from liberal Jewish New York Rep. Dan Goldman, whom Lander is challenging in the primary, because the money was “probably coming from AIPAC.” (Goldman has been endorsed by both AIPAC and J Street.)

While noting that AIPAC “absolutely deserves to be criticized, sidelined, and rejected for its decades of negative influence on American foreign policy,” Jacobs wrote that such critiques should be done “without dehumanizing language, and without hinting at a grand Jewish conspiracy.”

Such pushback from Jews who have worked with Mamdani is rare. JTA reached out to representatives for several of the mayor’s most visible Jewish allies on Monday, including Lander and Vermont Sen. Bernie Sanders, who spoke at the same rally. Sanders also criticized AIPAC. Neither returned requests for comment by press time. On social media after the rally, Lander celebrated the event, calling it “a tremendous honor” to rally alongside Mamdani.

IfNotNow and Jews For Racial and Economic Justice, two Jewish activist groups that endorsed Mamdani, similarly did not respond to requests for comment by press time. A spokesperson for Rep. Jerry Nadler, the retiring liberal Jewish Democrat who had endorsed Mamdani’s mayoral bid, also did not respond by press time.

J Street, the liberal pro-Israel lobby that positions itself as a foil to AIPAC, declined to comment on Mamdani’s remarks. Last month, hundreds of Jewish leaders criticized Yehuda Leiter, Israel’s ambassador to the United States, after Leiter called J Street a “cancer within the Jewish community.” Nadler was among the signatories of an open letter that said Leiter “dehumanizes fellow Jews.”

Centrist Jewish groups and figures, already no fans of Mamdani, also bashed his AIPAC comments. “Referring to fellow New Yorkers as ‘monsters’ is outrageous and dangerous, and the impact of your words extends far beyond politics,” American Jewish Committee CEO Ted Deutch wrote on X, addressing Mamdani.

Rep. Josh Gottheimer, a Jewish Democrat representing New Jersey, wrote, “Swap ‘AIPAC’ for ‘Jews’ and it’s the oldest antisemitic conspiracy theory in the books.”

Both posts were reposted by AIPAC, which otherwise did not comment.

U.K. PM Starmer leaves behind mixed record on antisemitism

(JTA) — U.K. Prime Minister Keir Starmer, who resigned the premiership on Monday, leaves behind a mixed record on fighting antisemitism in the Labour Party that Jewish organizations say will help shape their expectations for his successor.

Starmer announced that he was stepping down outside 10 Downing Street in the morning local time. He made the decision in the wake of mounting pressure from Labour members of Parliament and waning political support after the party’s devastating losses in the May 7 local elections and the success of political rival Andy Burnham in Manchester’s parliamentary election last week.

Burnham, the former mayor of Greater Manchester, has emerged as the leading contender after winning a Manchester-area by-election on Friday with 55% of the vote. Burnham has sought to position himself prominently on antisemitism and relations with the Jewish community in his bid to take over from Starmer.

In a post on X, Burnham thanked Starmer for his leadership and said the PM’s decision to resign “marks the beginning of a transition and it is important that this process is conducted in an orderly and responsible way. I will put myself forward as part of this process.”

Starmer confirmed he would remain on as caretaker prime minister until a successor was chosen.

“The question my party is asking now is whether I am best placed to lead us into the next general election,” he said. “I have heard the answer of my parliamentary party to that question, and I accept that answer with good grace.” 

The Jewish Labour Movement thanked Starmer in a post on X, noting that two years ago he inherited the party “at its lowest point” from former party leader Jeremy Corbyn, when it was “institutionally antisemitic.” It added, under Starmer, “our party has a clean bill of health on antisemitism.”

However, Starmer’s tenure was still met with plenty of criticism from the Jewish community over his handling of antisemitism, particularly in light of ongoing antisemitic attacks in the country. In recent months alone, four Hatzola ambulances were lit on fire; there were attempted attacks on three synagogues; two Jewish men in the Orthodox neighborhood of Golders Green were stabbed. Dozens of people have been arrested in connection with the incidents.

Starmer entered office in July 2024, leading his country’s thorny relationship with Israel in the aftermath of the Hamas Oct. 7, 2023, attack against the Jewish and the Gaza war that followed. He angered Israel with steps such as recognizing Palestine as a state and promising to uphold the International Court of Justice’s arrest warrant against Prime Minister Benjamin Netanyahu for war crimes.

With Starmer’s upcoming departure, focus has shifted to the contest to replace him, bringing renewed scrutiny to candidates’ positions on antisemitism, relations with the Jewish community, and Israel.

Starmer said he would give his successor his “full and unequivocal support,” adding that nominations would open on July 9 and conclude before the parliamentary summer recess on July 16.

Board of Deputies of British Jews President Phil Roseneberg posted on X, “When he took on the leadership of the Labour Party the first thing @Keir_Starmer said he would do is ‘tear out the poison of antisemitism by its roots’. His subsequent actions were transformative within the Party.”

He praised Starmer’s government for providing “unprecedented security funding,” and introducing legislation to proscribe the IRGC.

Burnham, for his part, has spoken out against antisemitism in the wake of violence attacks. Following the October 2025 Yom Kippur attack at the Heaton Park Congregation synagogue in Manchester, in which two people were killed, Burnham said in an official release, “Tonight, our first thoughts are with the families of those who have died, those injured and those traumatised by this – a horrific antisemitic attack on our Jewish friends and neighbours. We condemn it outright.”

He also wrote in a post on X on the same day, “Today we have witnessed a vile attack on our Jewish community on its holiest day. We condemn whoever is responsible and will do everything within our power to keep people safe.”

His positions on Israel and Gaza have also come under scrutiny. In a June 4 interview with The Guardian, Burnham did not invoke the term “genocide” in relation to the war in Gaza, but did say, “I can’t judge things of that enormity from where I am as mayor of Greater Manchester.”

He added, “But I do have concerns about the disproportionate nature of what has happened in terms of the destruction, and there has to be a full process of investigation and accountability.”

Additionally, 10 days after the Oct. 7 attacks, Burnham called for a ceasefire in a joint statement with 10 Greater Manchester leaders. The statement read in part, “We condemn unreservedly the appalling terror attacks on innocent civilians in Israel by Hamas on 7th October.”

The statement also noted that Israel has the right to take “targeted action within international law” to defend itself and to rescue its hostages, but added, “We also have profound concerns about the loss of thousands of innocent lives in Gaza, the displacement of many more and widespread suffering through the ongoing blockade of essential goods and services.”

Referencing his expected leadership bid, Culture Secretary Lisa Nandy told the Jewish News on June 17 that Burnham had a few weeks earlier met with Jewish communal leaders in Greater Manchester.

When it comes to Israel, Nandy said Burnham “believes in justice, so he’s acutely aware of the need for a safe homeland for Jewish people, you know, and the particularly unique historical reasons why Israel came into existence.”

NY cafe deactivates account after backlash over treatment of Rep. Goldman

(New York Jewish Week) — A Brooklyn café posted on Instagram that it refunded a purchase made by Rep. Dan Goldman, saying that it doesn’t serve “genocide enablers.”

“Do you see how it doesn’t taste like genocide juice?” the post by Poetica Coffee read. “Or are you still having a hard time telling the difference?”

In the post, the coffee shop included a photo of Goldman at the Lorimer Street location of their five Brooklyn spots. “Too bad we didn’t recognize you right away or we would have turned you away,” the post said.

The caption on the post said Goldman’s money is “probably coming from AIPAC anyways” and told Goldman never to come back. The post was accompanied by the song “F— You” by British singer-songwriter Lily Allen.

Jewish community leaders immediately condemned the post, which was deleted when Poetica Coffee deactivated its account Monday.

“Assigning collective blame to Jews or perceived supporters of Israel over disagreements with Middle East policies is the very definition of antisemitism,” Mark Treyger, CEO of the Jewish Community Relations Council of New York, said in a statement. “It is shameful and hateful, and businesses open to the public do not get to discriminate based on religion, ancestry, ethnicity, or stereotypes.”

According to its website, Poetica Coffee is “rooted in the Uzbek tradition where the guest is sacred, the books are unbanned, and the door is open to everyone.”

Goldman, who describes himself as “unabashedly pro-Israel,” is running for reelection in a contentious election Tuesday against former New York City Comptroller Brad Lander, an Israel critic who also identifies as a “liberal Zionist.” Lander’s campaign did not respond to request for comment from the Jewish Telegraphic Agency.

“I am sorry to see this post,” Goldman said in a statement earlier Monday. “The barista could not have been nicer to my 7-year-old daughter and me — allowing her to use the bathroom even though we had not purchased anything. I made sure to buy a coffee in return for her kindness. I hope you at least make sure she gets the tip that she deserved.”

Before deactivating its account, Poetica Coffee said it had been the recipient of multiple death threats, including at least one with Islamophobic rhetoric.

Goldman was refunded $9.82, according to now-deleted screenshots from Poetica’s post.
