In the consequent attempts at imperialism in the western Sudan there arose the largest of the African empires. Two circumstances, however, militated against this empire building: first, the fierce resistance of the heathen south made war continuous and slaves one of the articles of systematic commerce. Secondly, the highways of legitimate African commerce had for millenniums lain to the north. These were suddenly closed by the Moors in the sixteenth century, and the Negro empires were thrown into the turmoil of internal war. It was then that the European slave traders came from the southwest. They found partially disrupted Negro states on the west coast and falling empires in the Sudan, together with the old unrest of over-population and migration in the valley of the Congo. They not only offered a demand for the usual slave trade, but they increased it to an enormous degree, until their demand, added to the demand of the Mohammedan in Africa and Asia, made human beings the highest priced article of commerce in Africa. Under such circumstances there could be but one end: the virtual uprooting of ancient African culture, leaving only misty reminders of the ruin in the customs and work of the people. To complete this disaster came the partition of the continent among European nations and the modern attempt to exploit the country and the natives for the economic benefit of the white world, together with the transplanting of black nations to the new western world and their rise and self-assertion there. FOOTNOTES: [3] Ham is probably the Egyptian word "Khem" (black), the native name of Egypt. In the original myth Canaan and not Ham was Noah's third son. The biblical story of the "curse of Canaan" (Genesis IX, 24-25) has been the basis of an astonishing literature which has to-day only a psychological interest. It is sufficient to remember that for several centuries leaders of the Christian Church gravely defended Negro slavery and oppression as the rightful curse of God upon the descendants of a son who had been disrespectful to his drunken father!

III ETHIOPIA AND EGYPT Having viewed now the land and movements of African people in main outline, let us scan more narrowly the history of five main centers of activity and culture, namely: the valleys of the Nile and of the Congo, the borders of the great Gulf of Guinea, the Sudan, and South Africa. These divisions do not cover all of Negro Africa, but they take in the main areas and the main lines in development.
