Denying the Holocaust refers to the belief or assertion that the systematic genocide of six million Jews and millions of others by the Nazi regime during World War II did not occur or has been exaggerated. This denial often involves questioning the historical evidence, such as documents, testimonies, and photographs, that confirm the events of the Holocaust. Holocaust denial is widely discredited by historians and scholars, who emphasize the overwhelming evidence supporting the reality of the Holocaust. Such denial is often rooted in anti-Semitism and can contribute to the spread of hate and misinformation about Jewish history and identity.
