Glad you asked Indrajaya. Racism goes back, possibly as far as the Neanderthals. Modern Humans may have exterminated them. That is one explanation for their disappearance and the survival of Modern Humans that were in the World at the same time. Although people theorize they might have been able to inbreed with Modern Humans as there are some people today with traits that resemble Neanderthals. Actually, different species are unable to breed under normal circumstances. Thus there is only one Human Race and not different Races because our Males and Females all can make kids. But we begin to see people set each other apart from each other either from one culture to another or in castes which are internal aspects of a single system. Some even resort to skull deformation to make the point. In North America, we used to have people called Flatheads. You probably know some of this already.
