The Nordic race is one of the putative sub-races into which some late-19th to mid-20th century anthropologists divided the Caucasian race, attributing them to Northwestern and Northern Europe, particularly to populations such as Anglo-Saxons, Germanic peoples, Balts, Baltic Finns, Northern French, and certain Celts and Slavs. The physical traits of the Nordics were described as light eyes, light skin, tall stature, and dolichocephalic skull; the psychological traits as truthful, equitable, competitive, naive, reserved, and individualistic. Other supposed "Caucasian sub-races" were the Alpine race, Dinaric race, Iranid race, East Baltic race, and the Mediterranean race. In the early 20th century, beliefs that the Nordic race constituted the superior branch of the Caucasian race gave rise to the ideology of Nordicism.
