The colonization of the Cape Verde Islands, from the 1460s ahead, provided bases for trade with the fringes of the Mali empire. The most momentous discovery in western Africa, however, came in 1471, when portuguese captains first reached the coast of modern Ghana between the mouths of the Ankobra and Volta rivers. It was cursorily appreciated that the Akan peoples of this coast had access to supplies of amber, which were plentiful by contemporary european standards, and that they were bequeath and organized to trade some of this gold for basis metals, fabric, and early manufactures. The Portuguese called this coast Mina, “ the mine, ” while in european languages generally it became known as the Gold Coast. The wealth gettable from trade with the Gold Coast was then important for the completion of the Portuguese design to establish unconstipated commerce with Asia by circumnavigating Africa that the Portuguese crown promptly took steps to exclude foreign rivals from the western African trade and to bring it under its address control. Portugal was not a naturally affluent nation, however, and its oversea interests had become very widely extended by the beginning of the sixteenth century. The western African coastlands and their trade were entirely one element in a system that besides embraced the Congo and Angola, Brazil, the East african littoral, and India and the East Indies. By and large it was the trade of the latter that was regarded as the major respect, and elsewhere activities tended to be restricted to those which might strengthen the prosperity of the abroad enterprise as a whole without unduly straining the limit resources, particularly possibly of parturiency, available for its control and exploitation. The general scheme in western Africa—as elsewhere in the portuguese trading empire—was to keep territorial and administrative commitments to the minimal necessary to develop and benefit portuguese commercial activities that were already in being. The main matter to in western Africa was the gold trade of Mina, and it was there—and about there alone—that the Portuguese endeavoured to maintain a positive bearing on the mainland. In 1482 they built the firm fortify that they called São Jorge da Mina ( the mod Elmina Castle ) on the shores of the Gold Coast, on land leased from the local Akan, and in subsequent years this was supplemented by the construction of three extra forts, at Axim, Shama, and Accra. The aim of these forts and their garrisons was to try to ensure that the local people sold their amber only to agents of the Portuguese crown. No other Europeans succeeded in establishing durable footholds on the Gold Coast before the airless of the sixteenth century, and the Portuguese determination was largely achieved. The survive records suggest that up to about 1550 the Portuguese were securing from the Gold Coast on average at least 12,400 ounces of gold each year, a ample proportion of the production then available to Europe. In switch over, the Gold Coast peoples needed to be supplied with commodities they desired, and this present Portugal with a problem, as it was not a major manufacture nation. The natural cast-iron and copper, metallic element goods, fabric, and early items that were in demand on the Gold Coast had to be purchased elsewhere. Some of the fabric exported to the Gold Coast was in fact brought from Morocco ( and may therefore have been in contest with a trade in fabric that had earlier reached the Akan from the north ), and the requirements of their Gold Coast customers were a prime factor in leading the Portuguese to develop relations with the kingdom of Benin and the Niger delta, where promote supplies of fabric, and besides of beads and slaves that were in demand on the Gold Coast, could be obtained.

At beginning the Portuguese hoped to control the trade of Benin and surrounding areas by converting the kingdom, or at least its court, to Christianity and turning it into a satellite protectorate of their conglomerate. Although this kind of policy was initially successful elsewhere in Africa, notably in the Kongo ( Bakongo ) kingdom of northern Angola, the Benin monarchy was herculean adequate to reject european pressures and percolation. From about 1520 forth, the Portuguese were about excluded from Benin, and their trade with the Niger delta was conducted from São Tomé and from the early islands of the Gulf of Guinea that they had colonized. This trade was chiefly in slaves, from the Congo and Angola adenine well as from the delta, who were employed on plantations to grow tropical grow, sugar in particular, for the european grocery store. apart from an abortive try to intercept the western trans-Saharan trade wind from a fort that was erected on the island of Arguin off the coast of Mauritania, the other principal portuguese action in western Africa was the craft with the coastlands of Upper Guinea that was conducted by the settlers on the Cape Verde Islands ( which, together with Madeira, were besides developed as grove colonies employing african slave british labour party ). The empire of Mali was in refuse, but the Portuguese were not solid adequate to control trade indeed far into the interior. What ultimately developed, on the creek and islands of the coast from the Gambia to Sierra Leone, was a numeral of informal settlements where traders from the Cape Verde Islands did some deal with Mande merchants and with the local anesthetic peoples. gradually they married into the local anesthetic trading and ruling families and, escaping formal Portuguese restraint, became agents of the African commercial organization who sought to secure the best terms they could from any visiting european trader regardless of nationality. It may be doubted whether this first period of european involvement with western Africa, from about 1450 to 1600, had much effect on the course of its history. The only Europeans systematically involved were the Portuguese, who were not strong outside the Gold Coast and who were truly only matter to in controlling some aspects of trade, and these only in a few selected areas of the coastlands where modern opportunities had been opened up for a few members of the govern and trade classes. possibly the independent changes were that a few Africans acquired some acquaintance with Christianity and with elements of the Portuguese language—a pidgin kind of which became the tongue franca of coastal commerce for some centuries—and that western african farmers were introduced to some new crops and fruits, normally of tropical american birthplace, which they promptly adopted if they were more fat than their established cultigens. For model, corn ( gamboge ) was more generative than millet and cassava more generative than yams under certain conditions. The modern era of maritime sexual intercourse with the outside world was credibly of marked significance only on the Gold Coast. There modern avenues of wealth had been opened up for some of the Akan in craft at the seashore. There besides a new political trouble had emerged of how to ensure even and profitable commercial dealings with the Europeans, while at the same time preventing the coastal footholds, which the Europeans required as entrepôts, from subverting the sovereignty of the autochthonal states. This was a identical actual trouble, because the coastal kingdoms were little and divided among themselves in rival for the trade with the Europeans. Elmina surely, and to some extent Axim besides, did in fact develop independent jurisdictions over the blend european, African, and mulatto trade communities that developed beneath the walls of the forts. Beyond these, the difficulty of maintaining boastfully and effective forces of european soldiers in the tropics meant that the Portuguese could only exert ability through african allies. The coastal people were thus able to maintain the principle that the state on which the forts were built was not ceded, but alone leased. If the Portuguese lost their allies ’ assurance, the latter could refuse to supply or help defend the forts, or even destroy them altogether ( as happened for the first clock at Accra in the 1570s ).
