Ships sailing from the Gold Coast for home ports made a practice of picking up such slaves as they could easily secure. By 1450 the number reaching Portugal each year was placed at 600 or 700.[12] From this small and quite incidental beginning there developed a trade which eventually supplied Europe, the West Indies, North America and South America with black slaves.

Along the "Slave Coast," which extended from Cape Verde on the North to Cape St. Martha on the South, and in the hinterland there lived Negroes of varying temperaments and of varying standards of culture. Some of them were fierce and warlike. Others were docile and amenable to discipline. The former made indifferent slaves; the latter were eagerly sought after. "The Wyndahs, Nagoes and Pawpaws of the Slave Coast were generally the most highly esteemed of all. They were lusty and industrious, cheerful and submissive."[13]

The natives of the Slave Coast had made some notable cultural advances. They smelted metals; made pottery; wove; manufactured swords and spears of merit; built houses of stone and of mud, and made ornaments of some artistic value. They had developed trade with the interior, taking salt from the coast and bartering it for gold, ivory and other commodities at regular "market places."

The native civilization along the West coast of Africa was far from ideal, but it was a civilization which had established itself and which had made progress during historic times. It was a civilization that had evolved language; arts and crafts; tribal unity; village life, and communal organization. This native African civilization, in the seventeenth, eighteenth and early nineteenth centuries was confronted by an insatiable demand for black slaves. The conflicts that resulted from the efforts to supply that demand revolutionized and virtually destroyed all that was worthy of preservation in the native culture.

When the whites first went to the Slave Coast there was comparatively little slavery among the natives. Some captives, taken in war; some debtors, unable to meet their obligations, and some violators of religious rites, were held by the chief or the headman of the tribe. On occasion he would sell these slaves, but the slave trade was never established as a business until the white man organized it.

The whites came, and with guile and by force they persuaded and compelled the natives to permit the erection of forts and of trading posts. From the time of the first Portuguese settlement, in 1482, the whites began their work with rum and finished it with gun-powder. Rum destroyed the stamina of the native; gun-powder rendered his intertribal wars more destructive. These two agencies of European civilization combined, the one to degenerate, the other to destroy the native tribal life.

The traders, adventurers, buccaneers and pirates that gathered along the Slave Coast were not able to teach the natives anything in the way of cruelty, but they could and did give them lessons in cunning, trickery and double dealing. Early in the history of the Gold Coast the whites began using the natives to make war on commercial rivals. In one famous instance, "the Dutch had instigated the King of Fetu to refuse the Assins permission to pass through his territory. These people used to bring a great deal of gold to Cape Coast Castle (English), and the Dutch hoped in this way to divert the trade to their own settlements. The King having complied and plundered some of the traders on the way down, the Assins declared war against him and were assisted by the English with arms and ammunition. The King of Sabol was also paid to help them, and the allied army (20,000 strong) inflicted a crushing defeat on the Fetus."[14]

On another occasion, the Dutch were worsted in a war with some of the native tribes. Realizing that if they were to maintain themselves on the Coast they must raise an army as quickly as possible, they approached the Fetus and bargained with them to take the field and fight the Komendas until they had utterly exterminated them, on payment of $4,500. But no sooner had this arrangement been made than the English paid the Fetus an additional $4,500 to remain neutral![15]

Before 1750, when the competition for the slaves was less keen, and the supply came nearer to meeting the demand, the slavers were probably as honest in this as they were in any other trade with the natives. The whites encouraged and incited the native tribes to make war upon one another for the benefit of the whites. The whites fostered kidnaping, slavery and the slave trade. The natives were urged to betray one another, and the whites took advantage of their treachery. During the four hundred years that the African slave trade was continued, it was the whites who encouraged it; fostered it; and backed it financially. The slave trade was a white man's trade, carried on under conditions as far removed from the conditions of ordinary African life as the manufacturing and trading of Europe were removed from the manufacturing and trading of the Africans.
