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.

Congressional Hopeful Michael Blake Seeks to Erase AIPAC Support, Misleads on Past Trips to Israel

Michael Blake, a progressive Democrat running for US Congress in New York City, appeared to have recently made misleading statements about the nature of his previous trips to Israel and relationship with AIPAC, the country’s foremost pro-Israel lobbying group.
In Instagram comments, Blake characterized one of his visits to Israel as being done in his capacity as a reverend. Blake visited Israel in 2014 with the Jewish Community Relations Council (JCRC) and in 2017 with the AIPAC-affiliated American Israel Education Foundation.
“I attended a trip and spoke at previous events about my faith as an ordained reverend and about the Black & Jewish relationship but haven’t been involved in years,” he posted when asked to clarify his ties to AIPAC, which seeks to foster bipartisan support for the US-Israel alliance.
Blake, a former New York state assemblyman, is running an insurgent left-wing campaign to unseat incumbent US Democratic Rep. Ritchie Torres, a staunch supporter of Israel, in the state’s 15th congressional district.
Regarding previous support from AIPAC, Blake said, “Donations would have been minimal in the past.”

However, Blake’s social media comments contradict previous documentation about the nature of his trip to Israel and relationship with AIPAC. Although Blake asserted that he visited Israel with an AIPAC-linked group as a reverend, reports indicate that he attended AIPAC events through 2019 and only became ordained as a reverend following his 2020 Democratic primary defeat to Torres.
“The Bronx Democrat then gave up his Assembly seat to fall to Ritchie Torres in a 2020 congressional race. Since then, he’s run his public affairs firm, backed Maya Wiley’s 2021 run for mayor, and got ordained as a reverend,” Politico reported in 2024 in an article on Blake considering a bid at the time for New York City mayor.
Contrary to Blake’s assertions that he only participated with AIPAC as a reverend, the politician participated in multiple AIPAC events, including its annual policy conference in 2017 while serving as vice chairman of the Democratic National Committee (DNC). Skeptics have suggested that Blake invoked religion to minimize progressive blowback over his connections to AIPAC.
Last year, the New York Post first reported that Blake deleted several past social media posts touting his attendance at AIPAC events.
Since announcing his campaign to unseat Torres, Blake has lurched farther left on the Israeli-Palestinian conflict in an apparent attempt to court progressive voters. Blake has issued blistering statements condemning Israel of committing a so-called “genocide” in Gaza and vowed to vote against any military aid to the Jewish state.
“I am ready to fight for you and lower your cost of living while Ritchie fights for a Genocide. I will focus on Affordable Housing and Books as Ritchie will only focus on AIPAC and Bibi,” Blake posted on X in a statement last year announcing his candidacy, referencing Israel Prime Minister Benjamin Netanyahu.
In May 2025, however, during his failed campaign for mayor, Blake walked back his accusations of “genocide” against Israel, claiming that he regretted using the term to characterize the war in Gaza.
“It was wrong language to use,” Blake said, referencing his October 2023 post which accused Israel of committing genocide in Gaza. He apparently again reversed his stance when launching his congressional bid in New York’s 15th district.
Despite his efforts, Blake’s previous trips to Israel and history of praising the Jewish state have elicited skepticism among left-wing voters in New York City. Progressive critics have pointed to his 2017 speech at the annual AIPAC conference in which he lavished praise on Israel. In 2020, while speaking with Jewish Insider, he compared his experience as an African American to the struggles of Jewish people in Israel.
As the relationship between the Democratic Party and Israel continues to deteriorate following the breakout of the Israel-Hamas war, liberal politicians have continued to recalibrate their approach to Middle Eastern geopolitics. Many ambitious Democratic candidates have staked out positions on Israel more aligned with the far-left, progressive flank of the party, accusing the Jewish state of “genocide” and “ethnic cleansing” while vowing to oppose any arms sales to Jerusalem.
Despite his aggressive overtures to progressives, Blake’s campaign to unseat Torres still remains a longshot. The 15th district encompasses Riverdale, a heavily Jewish and affluent community and hub of pro-Israel activism. Polling suggests that Torres maintains heavy levels of support in his district, placing him among the most popular politicians in the state of New York.
Blake’s campaign did not respond to a request for comment for this story.

National support group for interfaith Jewish families guts staff amid funding crisis
(JTA) — A national nonprofit that supports interfaith Jewish families has slashed its workforce after facing an unanticipated budget shortfall.
18Doors announced on March 31 that it had “significantly” reduced its staff due to budget constraints. In fact, about two-thirds of the staff were laid off the week before the announcement, board member Laurie Beijen told the Jewish Telegraphic Agency.
The nonprofit had 15 staff members last August, according to an archived version of its website. This week, it lists four employees, nearly all in the C-suite.
CEO Mike Wise has stepped down, and 18Doors is now being led by Ellen Frank, the chief operating officer, and Adam Pollack, the chief program officer, the organization said.
Among those no longer at 18Doors are employees responsible for fundraising, creating digital content about interfaith inclusion and running a referral service to connect interfaith families and clergy. That service, which the organization says reached 2,000 families a year, remains operational, Beijen said, but “to a lesser degree.”
She said the budget crunch was complex and had come as a surprise. She cited in particular the squeeze felt by nonprofits like 18Doors in recent years as foundations and donors shifted their giving priorities toward Israel and fighting antisemitism.
“We were kind of caught off guard by the severity of our funding issues,” Beijen said. “It’s a myriad of causes that are sort of short, medium and long term, and we ended up just getting caught in this storm.”
Jodi Bromberg stepped down as CEO in 2024 after helming the organization for a decade, including during its 2020 rebrand from InterfaithFamily. The organization hired a search firm to find her replacement and a consulting firm to help draw up a strategic plan, which Beijen said it had been “on the cusp” of announcing before instead sharply contracting.
A delayed annual gift also scrambled budget planning, Beijen said, with a gap of just a few months sending the organization into a financial crisis. 18Doors declined to identify the donor or the size of the gift.
The nonprofit has raised $2 to 3 million a year in recent years and spent all of that or more, according to its filings with the IRS. Its significant donors have included the Marcus Foundation and Combined Jewish Philanthropies, the Jewish federation in Boston, where 18Doors is based. The Marcus Foundation and CJP did not respond to requests for comment.
In a statement emailed to the 18Doors community and posted on social media last week, the nonprofit wrote, “The Board has since secured necessary funding to stabilize the organization in the short term.”
Jewish philanthropic giving has changed since the Hamas attack on Israel on Oct. 7, 2023, with many donors choosing to focus on pro-Israel giving and causes that address antisemitism.
In December, the Shabbat dinner nonprofit OneTable laid off a quarter of its staff, citing donors’ funding priorities. The group is adapting its programming to include more Israel content.
At the recent Jewish Funders Network international conference, speakers, funders and philanthropy executives put a heavy emphasis on giving toward Israel and antisemitism-related issues, according to video and recaps of the conference.
Activists and educators in other areas say that while Israel and antisemitism are important issues, other causes are being left behind.
Founded in 2001, 18Doors says its mission is to encourage mixed-heritage families to engage in Jewish life, while encouraging Jewish communities and clergy to become more welcoming and inclusive.
18Doors’ vision of inclusion for interfaith families has grown closer to reality in the decades since its launch. In 2001, a Pew survey found that half of Jews who married in the previous 10 years had married non-Jews. Two decades later, in 2021, it found that the rate for marriages in the last decade had risen to 61%. Most children of the couples were being raised Jewish, the survey found, with participation in synagogue life and Jewish institutions common.
Two major seminaries recently began admitting students who are in relationships with people who are not Jewish, saying that they wanted to ordain rabbis who match the communities they serve. And in December, while continuing to prohibit intermarriages performed by its rabbis, leaders of the Conservative Movement formally apologized for decades of discouraging intermarriage between Jews and non-Jews and vowed to create new opportunities for inclusion in Conservative synagogues.
But advocates for interfaith families say much more needs to be done.
“The idea that being warm and welcoming is sufficient is false. There’s much more to learn and to do,” said Keren McGinity, an interfaith educator and scholar. “18Doors is important because they are part of the work that gets done, including training clergy.”
McGinity has her own experience with layoffs in the interfaith inclusion space. She was the interfaith specialist at the United Synagogue of Conservative Judaism before her position was eliminated last year.
She said she is optimistic that 18Doors’ financial crunch will be temporary — but she said she believed the Jewish philanthropic landscape needs to change nonetheless.
“What concerns me is that there should be more funding channeled towards engaging interfaith couples and families,” McGinity said.
Though no other institution has quite the national reach that 18Doors has, other organizations addressing some aspects of interfaith family life include the children’s Jewish literacy program PJ Library; Embark at Mem Global, a program for interfaith and mixed-heritage couples in their 20s and 30s; and Honeymoon Israel, which provides trips to Israel for “young couples of all backgrounds.”
Beijen said 18Doors is aiming to preserve its flagship 18-month clergy program, the Rukin Rabbinic Fellowship, which provides training for spiritual leaders who work with interfaith families.
Bromberg, the group’s former CEO, says 18Doors serves families like hers: Her wife is Catholic and they have children together. Now a consultant helping other nonprofits, she said the cuts at 18Doors signify both a crushing loss and a pressing question.
“These are long time, long-tenured staff. The Jewish community as a whole will lose the institutional knowledge and the relationships that it’s had through 18Doors, through the laying off of those staff,” she said.
Bromberg added, “The question it leaves in the minds of families like mine is: Whose priority are mixed-heritage and interfaith families in Jewish life?”

Jewish groups condemn Trump’s threat that a ‘whole civilization will die’ in Iran
(JTA) — Jewish groups were among those criticizing President Donald Trump and accusing him of using genocidal rhetoric on Tuesday after Trump posted online that “a whole civilization will die tonight” if Iran does not reopen the Strait of Hormuz.
“A whole civilization will die tonight, never to be brought back again,” wrote Trump in a post on Truth Social. “I don’t want that to happen, but it probably will. However, now that we have Complete and Total Regime Change, where different, smarter, and less radicalized minds prevail, maybe something revolutionarily wonderful can happen, WHO KNOWS?”
The president’s comments came hours before his 8 p.m. deadline for Iran on Tuesday to reach a deal to reopen the Strait of Hormuz, and were met by swift condemnation by a group of Senate Democrats, including Minority Leader Chuck Schumer.
“We speak today with one voice and one purpose: to condemn President Trump’s threat to extinguish an entire civilization,” Schumer wrote in a joint statement. “This is not strength. Intentionally destroying the power, water or basic infrastructure upon which tens of millions of civilians depend to punish the very civilians who suffer at the hands of the Iranian regime would constitute a war crime, a betrayal of the values this nation was founded on and a moral failure.”
Amy Spitalnick, the CEO of the Jewish Council for Public Affairs, condemned the president’s remarks, saying in a statement that there were “simply no words to describe the danger of a U.S. president openly threatening to erase an entire civilization.” She alluded to Jews’ history of facing genocidal leaders in her comments.
“Make no mistake: the president’s threats are deeply reprehensible to us as Jews and as Americans, and must be condemned by all leaders – regardless of their stance on the war with Iran,” Spitalnick said. “We know what it means when leaders call for communities and populations to be wiped out.”
Spitalnick was not the only Jewish leader to weigh in. Jeremy Ben-Ami, the president of the liberal pro-Israel lobby J Street, said in a statement that the group was “appalled by President Trump’s heinous remarks.”
“This language – a threat to carry out war crimes – is a searing violation of Jewish and American values, certainly will not lead to the de-escalation we desperately need and is a terrifying example of the senseless violence that has characterized Trump’s leadership,” Ben-Ami said, calling on Congress and the Cabinet to “do everything in their power to restrain and remove him.”
Other progressive Jewish groups and leaders accused Trump of promoting genocide, including Bend the Arc: Jewish Action, which wrote in a post on Instagram, “This is not strength. This is not safety. This is a call for genocide.”
Timothy Snyder, a historian of the Holocaust, also leveled the accusation against the president in a Substack post published on Tuesday titled “The president speaks genocide.”
“To bomb a bridge or a dam or a power plant or a desalinization facility, very likely a war crime in any event, could very well have a different legal significance, a genocidal one, if it takes place after the expression of genocidal intent by the commander and head of state,” Snyder wrote.
For some Jews, the president’s looming deadline for Iran carried added significance as it came during the final days of Passover — and as Iran continued to barrage Israel with missiles.
“Tonight, I pray that the Pharaohs who insist on our demise recognize the harm that they may bring on themselves,” Rabbi Arie Hasit, associate dean of the Schechter Rabbinical Seminary in Israel, wrote on Facebook. “That they recognize that Iran can put aside its insistence that Israel must be destroyed and that they can make the necessary steps to end this war.”
“And I pray that if they are overcome by Pharaoh, that no leader try to play the part of God,” Hasit continued. “That in the name of my future, we do not wipe out any civilization. That we understand that even the worst of enemies does not justify the use of the fiercest of our power.”
