Some people say the Holocaust did not happen at all, or was not as bad as historians say it was. This is called Holocaust denial. However, almost all historians agree that the Holocaust did happen and has been described correctly. Many Holocaust deniers profess that the Nazis did not kill as many people as historians say. Instead, they claim many of these people died from disease or lack of food, usually in order to shift blame from the Nazis. These ideas have been disproven by historical accounts, eyewitness evidence, and documentary evidence from the Nazis themselves. Also, many Jews were killed because Hitler ordered it. In some countries in Europe, including Germany, it is against the law to say that the Holocaust never happened.
