On page 21 of the book, "From Babylon to Timbuktu", Windsor writes; "Dividing the world along a color line was an idea that originated with the white supremacist in Europe after the Renaissance. The Europeans did not have any great civilization immediately after the fall of Greece and Rome."
Widsor goes on to write; "During the Middle Ages, the black nations of Africa and Asia had the greatest political, economical, educational, and military influence in the world. At this time, Europe existed in a state of darkness for a thousand years. In the seventeenth century and later, Europe began to emerge out of the slough of ignorance, and certain Germans and others conceived of themselves as belonging to a superior race."
