The bourgeoisie that led the development of capitalism were drawn from particular ethnic and cultural groups; the European proletariats and the mercenaries of the leading states from others; its peasants from still other cultures; and its slaves from entirely different worlds. The tendency of European civilization through capitalism was thus not to homogenize but to differentiate—to exaggerate regional, subcultural, and dialectical differences into "racial" ones. As the Slavs became the natural slaves, the racially inferior stock for domination and exploitation during the early Middle Ages, as the Tartars came to occupy a similar position in the Italian cities of the late Middle Ages, so at the systemic interlocking of capitalism in the sixteenth century, the peoples of the Third World began to fill this expanding category of a civilization reproduced by capitalism.
