Why Holocaust denial is false

The Holocaust is one of the best-documented events in history. Denial and distortion are not honest disagreements about the past; they are dishonest, and often antisemitic, attempts to rewrite it.

Denial and distortion

As the Holocaust Educational Trust explains, Holocaust denial tries to erase the Holocaust from history, for example by claiming it never happened. Distortion accepts that it happened but excuses, misrepresents or minimises it. Denial is easier to spot, while distortion can be harder to recognise.

The International Holocaust Remembrance Alliance's 2013 working definition lists forms of distortion, including:

The evidence

The Holocaust is established by many independent kinds of evidence that fit together:

The Irving case in 2000

In the UK, the clearest legal test of denial was the 2000 libel case David Irving v Penguin Books and Deborah Lipstadt. The historian Deborah Lipstadt had written that Irving was a Holocaust denier who distorted evidence. Irving sued for libel in London. The Holocaust Educational Trust's account notes that Irving claimed Hitler had not ordered the extermination of Europe's Jews. The court ruled against Irving and found that Lipstadt's claim that he had deliberately distorted evidence was "substantially true".

Common false claims, and why they fail

Why people deny it

Denial is usually motivated by antisemitism or by a wish to make Nazism look acceptable. It is not a good-faith historical debate. Historians argue about interpretation, causes and details, but not about whether the genocide happened.

What to do if you meet it

Whether a particular statement is unlawful depends on the facts and the law, and this site gives no legal advice.
