Racism has existed throughout history, it stems from the traditional ideas of racial supremacy held by most cultures, although in the modern world it exists without malice (think of patronism). These can manifest in such things as religion (The Chosen people) or social structure (Such as Slavery)
Athropologically, racism is a descendant from the evolutionary instinct that many animal species have which causes individuals to sort all creatures of their species into Us and Other. This is a very successful survival technique for social groups, allowing the easy distinction between the local (and thus likely friendly) population which the individual associated with, and remote (and thus likely hostile) groups which would likely be in contest for resources.
Racism is thus an extreme viewpoint which has progressed from clannism, through tribalism. The rise of what we could call Modern Racism coincides with the advent of the modern Nation-State, as the nation-state was originally defined heavily in terms of similar racial and social characteristics.
