In its early decades, the ADL benefited from being among the few highly centralized Jewish community relations organizations alongside the American Jewish Committee and American Jewish Congress. This characteristic gave these three organizations greater influence on the national Jewish community at a time when most local congregations and organizations were splintered, with little outreach to the broader community. By the 1970s, decentralization yielded greater influence. By this point the ADL had succeeded in developing local branches, though the central office remained significant even in terms of local branch activities.
Origins The ADL was founded in late September 1913 by
B'nai B'rith, with
Sigmund Livingston as its first leader. Its goals were to counter antisemitism, prejudice and discrimination. In 1913, Atlanta B'nai B'rith President
Leo Frank was convicted of the murder of a 13-year-old employee at a factory where he was superintendent; historians today generally consider Frank to have been innocent. The ADL's early strategy would be to pressure newspapers, theaters, and other businesses seen as defaming or discriminating against Jews; proposed methods included boycotts and pressuring advertisers, and it also considered demanding prior reviews of theater productions for antisemitism. Frank was granted a posthumous
pardon from Georgia in 1986 after ADL requests. In 1933, the ADL moved offices to Chicago and Richard E. Gutstadt became director of national activities. With the change in leadership, the ADL shifted from Livingston's reactive responses to antisemitic action to a much more aggressive policy. During the 1930s, the ADL, along with the AJC, coordinated American Jewish groups across the country in monitoring the activities of the
German-American Bund and its pro-Nazi, nativist allies in the United States. In many instances, these community-based defense organizations paid informants to infiltrate these groups and report on what they discovered. The longest-lived and most effective of these American Jewish resistance organizations was the Los Angeles Jewish Community Committee (LAJCC), which was backed financially by the Jewish leaders of the motion picture industry. The day-to-day operations of the LAJCC were supervised by a Jewish attorney,
Leon L. Lewis. Lewis was uniquely qualified to combat the rise of Nazism in Los Angeles, having served as the first national secretary of the Anti-Defamation League in Chicago from 1925 to 1931. From 1934 to 1941, the LAJCC maintained its undercover surveillance of the German-American Bund, the
Silver Shirts and dozens of other pro-Nazi, nativist groups that operated in Los Angeles. Partnering with the American Legion in Los Angeles, the LAJCC channeled eyewitness accounts of sedition on to federal authorities. Working with the ADL, Leon Lewis and the LAJCC played a strategic role in counseling the
McCormack-Dickstein Committee investigation of Nazi propaganda activities in the United States (1934) and the Dies Committee investigation of "un-American activities" (1938–1940). In their final reports to Congress, both committees found that the sudden rise in political
antisemitism in the United States during the decade was due, in part, to the German government's support of these domestic groups. Paralleling its infiltration efforts, the ADL continued its attempts to reduce antisemitic caricatures in the media. Much like the
NAACP, it chose a non-confrontational approach, attempting to build long-lasting relationships and avoid backlash. The ADL requested its members avoid public confrontation, instead directing them to send letters to the media and advertising companies that included antisemitic or racist references in screening copies of their books and movies. This strategy kept the campaigns out of the public eye and instead emphasized the development of a relationship with companies. The ADL was critical of
red-baiting and
McCarthyism in the 1950s. The ADL rejected accusations that the Rosenberg trial was influenced by antisemitism. Judge
Irving Kaufman, who ordered the execution of the Rosenbergs, was a member of the ADL's Civil Rights committee. In 1952,
Lucy Dawidowicz wrote in
Commentary that Jewish communists viewed the ADL and other mainstream Jewish organizations as "reactionary, fascist-collaborating oligarchs and conspiratorial enemies both of democracy and their own oppressed people." In 1952, the ADL and other Jewish organizations released a joint statement rejecting the claims of the
National Committee to Secure Justice in the Rosenberg Case that the trial was motivated by antisemitism. The statement characterized the Rosenberg Committee as trying to "inject the false issue of anti-Semitism". A 1952 ADL document claimed that "The Communists, in their worldwide propaganda attack defending the convicted atom spies, Ethel and Julius Rosenberg, provide a vivid example of the technique of falsely charging anti-Semitism to hide conspiracy." The ADL campaigned for
civil rights legislation including the
Civil Rights Act of 1964 and the
Voting Rights Act of 1965. The ADL and the NAACP worked together to discredit the far right in the United States. According to Mathew Delleck, author of a history of the US far right in this period, the ADL, leading a multi-racial liberal coalition, was perhaps the most effective group in discrediting extremist right wing elements in the United States. After the
1967 Arab–Israeli War, the ADL, with the support of
AIPAC founder
Isaiah L. Kenen, "sought to portray certain 'anti-Israel' actions as anti-Semitic," especially with regard to international calls for Israel to end its
occupation of the West Bank, according to historian
Ilan Pappé. From the early 1970s, the ADL sought to popularize a discourse of 'new antisemitism' identifying anti-Zionism with antisemitism. Under the tenure of Perlmutter and his 1978–1983 co-director of interreligious affairs
Yechiel Eckstein, the ADL shifted its approach to the evangelical Christian movement. Through the 60s and early 70s, the ADL had conflicted with the American Jewish Congress over their collaborations with evangelicals. Perlmutter and Eckstein changed this orientation, increasing collaborations and developing long-lasting lines of communication between the ADL and evangelical groups. This collaboration continued under the Foxman administration.
The New Anti-Semitism After the
1967 Arab–Israeli War, the ADL— with the support of
AIPAC founder
Isaiah L. Kenen, according to historian
Ilan Pappé In 1974, ADL leaders
Arnold Forster and
Benjamin Epstein published the book
The New Anti-Semitism, in which they present the term '
new antisemitism' and the idea that a new form of discrimination against Jews has emerged, especially with regard to
Zionism and the
State of Israel. The book has been criticized for conflating
anti-Zionism—opposition to Zionism—with
antisemitism—discrimination against
Jews. In the 1970s, the ADL partnered with
Federal Bureau of Investigation (FBI) field offices, sharing information learned from the monitoring of extremist groups. In 1977, the ADL opened a headquarters in
Jerusalem. It opposed an
anti-Mormon film called
The God Makers in 1982, viewing it a challenge to religious freedom. San Francisco police searched two offices of the ADL in April 1993, suspecting it of having monitored thousands of activists; in the search, they confiscated police records including fingerprints and copies of confidential reports, according to court documents. During the investigation, a private investigator hired by the ADL, Roy H. Bullock, told police he had tracked
skinheads,
white supremacists,
Arab Americans, and critics of Israel. He confessed to trying to find "any sexual impropriety" on the late anti-
apartheid activist
Desmond Tutu. News of the investigation led Arab Americans listed in the ADL's files to sue the ADL, contending invasion of privacy and the forwarding of confidential information to Israel and South Africa. It settled with three remaining plaintiffs in 2002 for $178,000. In 1994, ADL became involved in a dispute between neighbors in Denver, Colorado. The Aronson family reported this dispute to the ADL, which involved the Quigley family making antisemitic comments. The ADL advised the Aronsons to record the Quigleys' private telephone conversations via a police scanner. These recordings were legal at the time, but federal wiretap law was amended shortly after to make it illegal to record conversations from a cordless telephone, to transcribe the material, and to use the transcriptions for any purpose. ADL Regional Director Saul Rosenthal described the recorded remarks as part of a "vicious antisemitic campaign". This led to the family being ridiculed and excluded in their community and to career damage. These recordings were used as basis for a federal civil lawsuit against the Aronson family and the ADL for
defamation. The Quigleys and Aronsons settled out-of-court, This was the first-ever verdict against the ADL. Only once before had the League been subject to a defamation trial, a case it won in 1984. Other cases were dismissed before reaching trial.
2000s In 2003, the ADL opposed an advertising campaign by
People for the Ethical Treatment of Animals (PETA) called "Holocaust on Your Plate" that compared animals killed in the meat industry to victims of the
Holocaust. In 2005, PETA apologized for causing distress to the Jewish community through the campaign, though in 2008, the
Chief Rabbinate announced that it was planning to gradually phase out the use of the "shackle and hoist" method of
kosher slaughter in Israel and South America, in part in response to pressure from PETA. As of 2007, the ADL said it was archiving
MySpace pages associated with white supremacists as part of its effort to track extremism. The ADL opposed
2008 California Proposition 8, a ballot successful initiative that banned same-sex marriage. It did so alongside Jewish organizations, including the National Council of Jewish Women and the Progressive Jewish Alliance. The ADL filed
amicus briefs urging the
Supreme Court of California,
Ninth Circuit, and the
Supreme Court to invalidate Prop 8. In 2015, the ADL opposed the
State Religious Freedom Restoration Acts, state laws that used the United States Supreme Court decision in
Burwell v. Hobby Lobby Stores, Inc. recognizing a for-profit corporation's claim of religious belief. The ADL opposed these laws out of concern they largely targeted LGBT people or denied access to contraceptives to employees of religiously owned businesses. The ADL became independent from B'nai B'rith in 2009, dropping the reference to the other organization in its name. In November 2014, the organization announced that
Jonathan Greenblatt, a former Silicon Valley tech executive and former
Obama administration official who had not operated within the Jewish communal organization world prior to his hiring, would succeed
Abraham Foxman as national director in July 2015. Foxman had served as national director since 1987. The ADL board of directors renewed Greenblatt's contract as CEO and national director in fall 2020 for a second five-year term. In 2018, Esta Gordon Epstein was elected to a three-year term as national chair of the ADL's governing board of directors; she was the second woman to hold the organization's top volunteer leadership post. The ADL repeatedly accused
Donald Trump, when he was a presidential candidate in 2016, of making use of antisemitic tropes or otherwise exploiting divisive and bigoted rhetoric during the
2016 presidential election campaign. The ADL accused President Trump of politicizing charges of antisemitism for partisan purposes, and for continued use of antisemitic tropes. The ADL said it was facing a discredit campaign for its criticism of Trump. In mid-2018, the ADL raised concerns over President Donald Trump's nomination of then-DC Circuit Court of Appeals judge
Brett Kavanaugh as an Associate Justice of the
United States Supreme Court. Subsequently, in another move that enraged many on the right, the ADL called for the resignation or firing of
Trump administration official
Stephen Miller, the architect of the administration's immigration policy, on the basis of his association with white supremacists. The ADL says it has participated in
YouTube's Trusted Flagger program and has encouraged YouTube to remove videos that they flag as
hate speech, citing the need to "fight against terrorist use of online resources and cyberhate." The ADL's Center on Technology and Society launched a survey in 2019 exploring online harassment in video games. It found that the majority of surveyed players experienced severe harassment of some kind, and the ADL recommended increased content moderation from game companies and governments. On the other hand, the survey found that over half of players experienced some form of positive community in video games. A separate, earlier survey of the general population found that around a third of people have experienced some form of online harassment. In July 2017, the ADL announced that they would be developing profiles on 36
alt-right and
alt-lite leaders. In 2019 and 2020, ADL executives and staff testified multiple times in front of congressional committees concerning the dangers of right-wing domestic extremists. In a report from 2018, the ADL noted that the majority of domestic extremist-related murders in the United States over the past decade had been committed by white supremacists. In a 2023 report, white supremacists were also deemed responsible for 45% of right-wing extremism in the US from 2017 to 2022.
2020s In 2020, the ADL joined with the
NAACP,
Color of Change,
LULAC,
Free Press, the
National Hispanic Media Coalition and other organizations in the
Stop Hate For Profit campaign. The campaign targeted online hate on Facebook, with over 1000 businesses pausing their ad buys on Facebook for a month. Subsequently, in September 2020, the campaign organized celebrity supporters including
Sacha Baron Cohen,
Kim Kardashian, and
Mark Ruffalo. In 2020, the ADL trained staff to edit Wikipedia pages, but after the project caused Wikipedia editors to criticize this as a
conflict of interest, the ADL said it suspended the project in April 2021. At the time, the ADL was considered a
reliable source on Wikipedia, and the ADL said its staff complied with Wikipedia policies by disclosing their affiliations, but some Wikipedia editors objected that the project cited ADL sources disproportionately and did not reflect the volunteer spirit of the website, especially in heavily editing its own Wikipedia article. An internal email obtained by
The Guardian in 2024 showed that in May 2020, the ADL had surveilled and produced a "threat assessment" report on a Black
Indianapolis activist who worked with the
Deadly Exchange campaign in opposition to exchange programs between American and Israeli police. The email contained a photo and personal information about the activist. The ADL employee who shared the email with
The Guardian said that "threat assessments" are conducted regularly by the ADL and that many staff members opposed the spying. In early January 2021, the ADL called for the removal of Donald Trump as president in response to the
United States Capitol attack and described the relationship of the storming of the Capitol to the far-right and antisemitic groups. In April 2021, Jonathan Greenblatt released a letter calling on the right-wing American network
Fox News to drop commentator
Tucker Carlson from its lineup, saying that Carlson had espoused the
white genocide conspiracy theory on his show. This call appeared shortly after research indicating that many who participated in the 2021 storming of the United States Capitol had been influenced by this conspiracy theory. Carlson responded, saying "Fuck them" regarding the ADL, describing the ADL's call as politically motivated and defending his statements. In 2023, Fox dropped Carlson, a move welcomed by ADL leadership. In 2022, the ADL revised its 2020 definition of
racism from "the marginalization and/or oppression of people of color based on a socially constructed racial hierarchy that privileges White people" to occurrence "when individuals or institutions show more favorable evaluation or treatment of an individual or group based on race or ethnicity." Also in 2022, the ADL published an analysis of a leaked list of members of
Oath Keepers, an American far-right, anti-government militia. Of 38,000 names on that list, the ADL identified "at least 373 Oath Keepers currently serving in law enforcement", plus 117 active duty military, and 1,100 former law enforcement officers. In November 2022, the ADL acquired JLens, a pro-Israel advocacy group started in 2012 which campaigns against incentives for economic disengagement with Israel in
environmental, social, and corporate governance (ESG) investing guidelines. JLens publishes company rankings based on participation in boycotts of Israel and publishes guidelines on investing used by around 30 Jewish companies with portfolios totaling around $200 million. JLens launched a campaign criticizing
Morningstar, Inc., a campaign the ADL collaborated on prior to the 2020 acquisition. The ADL said it would contribute funding to JLens. The ADL tracked rapid growth in hate speech and harassment on
Twitter after
Elon Musk bought the social network in 2022. Musk also accused the ADL of defamation and threatened to sue it, writing that advertising revenue was "still down 60%, primarily due to pressure on advertisers by @ADL (that's what advertisers tell us), so they almost succeeded in killing X/Twitter!" The ADL said as a matter of policy it did not comment on legal threats, but that it had recently met with X leadership including CEO
Linda Yaccarino, who had thanked the ADL's CEO on the platform. Greenblatt later praised Musk after he announced policy banning phrases such as "
decolonization" and "
from the river to the sea" on Twitter. Multiple ADL board members threatened to quit over the organization's praise for Musk, and
Yael Eisenstat, a top ADL executive, resigned; many working with the ADL have described Greenblatt's support for Musk as undermining the organization's ability to focus on right-wing antisemitism online. In February 2024, the institute appointed documentary producer and journalist Deborah Camiel as its leader.
Gaza war and genocide During the
Gaza war and
genocide, the Anti-Defamation League under Jonathan Greenblatt has been accused of
exploiting the accusation of antisemitism to silence
criticism of Israel. On October 25, Greenblatt of the ADL and Alyza D. Lewin and
Kenneth L. Marcus of the
Brandeis Center wrote university presidents a letter calling on them to investigate
Students for Justice in Palestine for "potential violations of the prohibition against materially supporting a foreign terrorist organization", adding that "universities must also update their code of conduct to ensure that harassment and support for terrorism have no place on campus." According to
The Nation columnist
Spencer Ackerman, "The ADL provided not a shred of evidence for that incendiary, potentially life-ruining accusation." In June 2025, the ADL laid off 22 employees as part of a shift away from broader civil rights work in favor of focusing on antisemitism. In September 2025, the ADL deleted its Glossary of Extremism, which contained thousands of entries on neo-Nazi groups, militias and antisemitic conspiracies, after facing criticism by Elon Musk. Musk called it a "hate group" and accused it of being anti-Christian in nature. The attacks came after the
assassination of Charlie Kirk brought new attention to the ADL's historical work on right wing antisemitism. Following the backlash from Musk and other prominent conservatives, the
FBI cut ties with the ADL and Director
Kash Patel made a statement condemning the ADL. Some former employees blamed the organization's shift of focus to combating pro-Palestinian activism for alienating progressive groups, few of which criticized the FBI's decision. In October 2025, the ADL announced the launch of a national legal service network to support victims of antisemitism and provide legal counsel on a pro-bono basis. One of the nation's largest law firms,
Gibson, Dunn & Crutcher, is participating in partnership with the ADL. A total of 40 law firms in the United States have agreed to join the network, providing a pool of 39,000 attorneys. That month, it removed a statement stating that it would protect civil rights from its website. Following
Zohran Mamdani's victory in the
2025 New York City mayoral election, the ADL announced a 'Mamdani Monitor' to "track and monitor Mamdani administration policies and appointments" with regard to matters it says "impact Jewish community safety and security". In December 2025, Catherine Almonte Da Costa resigned from her role as Mamdani's director of appointments after the ADL resurfaced antisemitic social media posts made by Da Costa when she was a teenager. Mamdani's transition team said it would revamp its vetting process. Several days later, the ADL announced that it had dug into the social media histories of over 400 individual members of Mamdani's transition committee and identified social media postings about Israel and Zionism. Mamdani said the ADL's report often ignores the distinction between antisemitism and criticism of the Israeli government, which distracts from what he called "the very real crisis of antisemitism we see not only just in our city but in the country at large".
J Street criticised the ADL's report and said it was "deeply concerned by the ADL's ongoing use of its so-called ‘Mamdani Monitor,' which goes well beyond combating antisemitism and too often conflates legitimate political speech with hate". == Political positions ==
