Adolf Hitler was identified by the Nazis as a member of the "Aryan" race, which they believed was at the top of the racial hierarchy. The Nazis referred to German Aryans as the "master race" and believed that they had to protect Germans from inferior races. To Hitler and the Nazis, Jewish people were the biggest threat to the Aryan race. However, a 2010 DNA test cited by Belgian news magazine Knack claimed that Hitler could be a descendant of both Jews and Africans.
