Holocaust denial is the act of denying the genocide of Jews and other groups in the Holocaust during World War II. Holocaust denial often includes the following claims: that Nazi Germany's Final Solution was aimed only at deporting Jews from the Reich, but that it did not include the extermination of Jews; that Nazi authorities did not use extermination camps and gas chambers to mass murder Jews; and that the actual number of Jews killed was significantly (typically an order of magnitude) lower than the historically accepted figure of 5 to 6 million.
