Nazi racial theoriesThe Nazi Party adopted and developed several pseudoscientific racial classifications as part of its ideology (Nazism) in order to justify the genocide of groups of people which it deemed racially inferior. The Nazis considered the putative "Aryan race" a superior "master race", and they considered black people, mixed-race people, Slavs, Roma, Jews and other ethnicities racially inferior "sub-humans", whose members were only suitable for slave labor and extermination.
Historical race conceptsThe concept of race as a categorization of anatomically modern humans (Homo sapiens) has an extensive history in Europe and the Americas. The contemporary word race itself is modern; historically it was used in the sense of "nation, ethnic group" during the 16th to 19th centuries. Race acquired its modern meaning in the field of physical anthropology through scientific racism starting in the 19th century. With the rise of modern genetics, the concept of distinct human races in a biological sense has become obsolete.
Master raceThe master race (Herrenrasse) is a pseudoscientific concept in Nazi ideology in which the putative "Aryan race" is deemed the pinnacle of human racial hierarchy. Members were referred to as "Herrenmenschen" ("master humans"). The Nazi theorist Alfred Rosenberg believed that the "Nordic race" was descended from Proto-Indo-Europeans, who he believed had pre-historically dwelt on the North German Plain and may have ultimately originated on the lost island of Atlantis.
Aryan raceThe Aryan race is an obsolete historical race concept that emerged in the late-19th century to describe people of Proto-Indo-European heritage as a racial grouping. The terminology derives from the historical usage of Aryan, used by modern Indo-Iranians as an epithet of "noble". Anthropological, historical, and archaeological evidence does not support the validity of this concept.
NordicismNordicism is an ideology which views the historical race concept of the "Nordic race" as an endangered and superior racial group. Some notable and seminal Nordicist works include Madison Grant's book The Passing of the Great Race (1916); Arthur de Gobineau's An Essay on the Inequality of the Human Races (1853); the various writings of Lothrop Stoddard; Houston Stewart Chamberlain's The Foundations of the Nineteenth Century (1899); and, to a lesser extent, William Z. Ripley’s The Races of Europe (1899).
Scientific racismScientific racism, sometimes termed biological racism, is the pseudoscientific belief that the human species can be subdivided into biologically distinct taxa called "races", and that empirical evidence exists to support or justify racism (racial discrimination), racial inferiority, or racial superiority. Before the mid-20th century, scientific racism received credence throughout the scientific community, but it is no longer considered scientific.
