The Nordic race was a racial concept which originated in 19th century anthropology. It was considered a race or one of the putative sub-races into which some late-19th to mid-20th century anthropologists divided the Caucasian race, claiming that its ancestral homelands were Northwestern and Northern Europe, particularly to populations such as Anglo-Saxons, Germanic peoples, Balts, Baltic Finns, Northern French, and certain Celts and Slavs. The supposed physical traits of the Nordics included light eyes, light skin, tall stature, and dolichocephalic skull; their psychological traits were deemed to be truthfulness, equitability, a competitive spirit, naivete, reservedness, and individualism. In the early 20th century, the belief that the Nordic race constituted the superior branch of the Caucasian race gave rise to the ideology of Nordicism.
With the rise of modern genetics, the concept of distinct human races in a biological sense has become obsolete. In 2019, the American Association of Biological Anthropologists stated: "The belief in 'races' as natural aspects of human biology, and the structures of inequality (racism) that emerge from such beliefs, are among the most damaging elements in the human experience both today and in the past."
The Russian-born French anthropologist Joseph Deniker initially proposed "nordique" (meaning simply "northern") as an "ethnic group" (a term that he coined).
He defined nordique by a set of physical characteristics: the concurrence of somewhat wavy hair, light eyes, reddish skin, tall stature and a dolichocephalic skull. Of six 'Caucasian' groups Deniker accommodated four into secondary ethnic groups, all of which he considered intermediate to the Nordic: Northwestern, Sub-Nordic, Vistula and Sub-Adriatic, respectively.
The notion of a distinct northern European race was also rejected by several anthropologists on craniometric grounds. German anthropologist Rudolf Virchow attacked the claim following a study of craniometry, which gave surprising results according to contemporary scientific racist theories on the "Aryan race".
