Who are notable figures promoting Holocaust denial?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
Holocaust denial is promoted today by a mix of long‑standing agitators (David Irving, Ernst Zündel), extremist networks and modern online subcultures including white supremacists and some Islamist political figures; organized campaigns and social‑media amplification make denial and distortion resurgent concerns (Auschwitz Museum on David Irving; Zündel publishing) [1] [2]. Watchdogs and governments report rising online denial and uneven platform enforcement, with NGOs and bodies like UNESCO, IHRA and the U.S. State Department documenting the spread and calling for counter‑measures (UNESCO; IHRA; U.S. State Department) [3] [4] [5].
1. The familiar faces: yesterday’s professional deniers
A small number of individuals built the postwar movement that openly rejected the Holocaust as recorded history; the UK’s David Irving is singled out by the Auschwitz Museum as “the best known Holocaust denier in the UK,” and Ernst Zündel ran Samisdat Publishers to print denial tracts such as Did Six Million Really Die? [1] [2]. These figures created texts and networks that later actors and groups still draw on [2].
2. Transnational alliances: from Beirut and Tehran to North America
Holocaust denial has not been limited to one geography: Western deniers forged ties with actors in the Middle East and elsewhere. The Institute for Historical Review (IHR) and its conferences sought broader legitimacy by soliciting non‑neo‑Nazi supporters, and Iran hosted a global denial conference in 2006 that attracted Western deniers such as Bradley Smith and David Duke, illustrating cross‑border alliances [2] [6].
3. Extremist movements and modern agitators
Contemporary promoters include white supremacists and antisemitic groups in the U.S. and Europe; the Anti‑Defamation League lists figures and organizations — including the Goyim Defense League and online white‑supremacist networks like “Daily Stormer” affiliates — as drivers of denialist propaganda and on‑the‑ground campaigns [6]. The U.S. Holocaust Memorial Museum and ADL reporting emphasize that denial now often appears alongside broader extremist recruitment online [7] [6].
4. Political leaders and state‑adjacent rhetoric
Some political leaders have publicly questioned or minimised the Holocaust. The Wikipedia entry compiled in reporting notes former Iranian President Mahmoud Ahmadinejad’s frequent public questioning of the historical record, sometimes framed as challenging “legend” narratives [2]. Available sources do not mention other specific contemporary heads of state beyond those cited in these sources.
5. The internet as the movement’s new amplifier
Multiple sources report that the internet is now the principal channel for spreading denial. UNESCO’s study, the USHMM analysis and investigative pieces show social platforms host denial and distortion at scale, with Telegram and TikTok flagged for particularly high shares of problematic content and algorithmic promotion complicating moderation [3] [7] [8]. Fortune documented millions of views for Hitler and denial clips on Instagram in 2025, even while platforms say they remove vast amounts of such content [8].
6. Denial morphs into distortion and contemporary narratives
Watchdogs show a spectrum from outright denial (claiming the Holocaust never happened) to distortion (minimization, comparison, or glorification). ENMA and IHRA warn that distortion has surged in Europe after geopolitical shocks, and CyberWell reported new forms of denial tied to recent conflicts that borrow classic denial tactics [4] [9].
7. Legal and civic responses: patchwork of laws and advocacy
States respond differently: many European nations criminalize public Holocaust denial, while the U.S. protects such speech under the First Amendment; the legal landscape shapes where promoters operate openly and where they rely on online channels [10] [7]. NGOs and international bodies press platforms and educators to “protect the facts” through education, moderation and research [11] [3].
8. How to read claims about “who” is promoting denial
Sources reveal three distinct promoter types: established denial authors and publishers (Irving, Zündel) [1] [2]; extremist groups and influencers repackaging denial for recruitment (GDL, Daily Stormer affiliates, Fuentes example in ADL reporting) [6]; and political actors or media systems in some countries that amplify denial as political rhetoric (Ahmadinejad and Tehran conference) [2] [6]. Different sources emphasize different drivers; UNESCO foregrounds platform mechanics while ADL names organized extremist groups [3] [6].
Limitations and notes on sources
Reporting here relies on the provided archives and watchdog reports; lists of “notable figures” vary by source and context. Wikipedia and museum pages document historical actors [2] [1], ADL and UNESCO document contemporary networks and online dynamics [6] [3]. Available sources do not provide an exhaustive, up‑to‑the‑minute roster of every individual promoter active worldwide; for names beyond those cited here, current reporting would need to be consulted (not found in current reporting).
