http://en.wikipedia.org/wiki/Caucasian_raceThe concept of a Caucasian race or Varietas Caucasia was developed around 1800 by Johann Friedrich Blumenbach, a German scientist and classical anthropologist.[4] Blumenbach named it after the Caucasian peoples (from the Northern Caucasus region), whom he considered to be the archetype for the grouping.[5] He based his classification of the Caucasian race primarily on craniology.[6] Blumenbach wrote:
"Caucasian variety - I have taken the name of this variety from Mount Caucasus, both because its neighborhood, and especially its southern slope, produces the most beautiful race of men, I mean the Georgian; and because all physiological reasons converge to this, that in that region, if anywhere, it seems we ought with the greatest probability to place the autochthones (birth place) of mankind."[7]

So, you see, it is most common in Germanic nations. In Serbia this term is never used for defining major groups("races") of people.
When we say on this Forum that Albanians are Caucasians we are referring to their geographical origin - Caucasus Mountains area, near Black Sea.
