In fact the gold mines of Africa occidental person, with the time had been if becoming preference of the European merchants, since India were much more distant and inaccessible for sea, added to the short-term headquarters of profits, as already it was said. Thornton was happy in clarifying in them that the Europe already had knowledge of Africa occidental person and its mines, therefore some Mediterranean countries since the bizantino empire were supplied with the gold of this African region, thus demystifying the idea erroneamente imposed by the new history of that the Europe did not have knowledge of the African world occidental person. In what it says respect to the European settling of Africa, is of extreme importance to detach that it was not only possible for its warlike supremacy. As it was said, Africa already commercialized intern and external and of ownership of this knowledge, after some battles badly succeeded on the part in such a way of Africa how much of the Europe, the Europeans had started a long process of commercialization and ' ' parceria' ' with the African coast, first ' ' merchandises – ouro' ' later ' ' weapons – escravos' ' or ' ' horses? escravos' '. In relation to the merchandises, the author displays that they were varied, went of semimanufactured products (its majority) as leather, has covered, gold, rubber and ivory, the manufactured products as iron and fabric, however with emphasis in the iron, the author explains that although Africa also to be a producer of this mineral, by the way, of better quality, the African iron was more expensive due the scarcity of the substance cousin for the casting of the mineral and therefore more viable and lucrative the importation of the European iron for devices that did not need one better quality of the steel. Portugal, however, did not supply to as much iron how much Holland and England, for obedience to the papal order to prevent the commercialization of products used in the manufacture of weapons.
