Caucasian is a large and rather indefinite division of mankind which in the eighteenth century was comprised of the chief races of Europe, North Africa and Southwest Asia. All mankind was divided into five species by Johann F. Blumenbach (1752-1840) in 1781. The other four were Mongolian, Ethiopian, American and Malay.
