The Arrival of Europeans and the Later Trans-Saharan Trade
Europeans had long known that there were three ancient trade routes through the Saharan Desert. In the western Sahara, the route ran from Taghaza to Timbuktu. Farther east, a second route connected the oasis town of Ghadames with trade centers in Hausaland. Finally, there was a route connecting the major Mediterranean port city of Tripoli with Bornu in the Central African interior. Centuries of caravan trade along these routes had not, however, made them any less hazardous. Thus, those who knew the routes and the location of key cities and oases, and who appreciated the inherent risks of Saharan weather patterns, were in the best position to control and profit from trans-Saharan trade. It was therefore in the best interest of the Muslim and Arab travelers and caravanners who possessed this knowledge to monopolize it. To share it would undercut their profits. Consequently, European maps of the African interior remained sketchy; distances were mere estimates, and the locations of important cities such as Timbuktu and Kano were a matter of guesswork. Add to this the threat of raids and the possibility of a hostile merchant population, and to Europeans the undertaking of a trans-Saharan journey by themselves seemed likely to be disastrous.
In the fifteenth and sixteenth centuries, however, pressures mounted on European powers to boost their sources of national wealth—an urgency inflamed by the discovery of the Americas and the expense of traveling and setting up competing colonies there. Increasingly, European states desired to circumvent the intermediaries who controlled the trade in exotic luxury goods and vital raw materials, such as Chinese silk, Indonesian spices, and African gold. It was no easy matter to wrest control from these merchants, whose monopolies were often supported by kingdoms and states that benefited from it. The challenge was quite severe for poorer European states, such as Portugal.
When the Portuguese began their voyages along the West African coast, their immediate goal was not to discover a new trading route to India; rather, it was to secure West African gold. Europeans had been aware of the region’s goldfields since the fourteenth century, when Sudanic gold had been imported as a raw material to mint European coins. By the mid-fifteenth century, the Portuguese had made inroads along the Senegambian coast, raiding Amazigh settlements on the island of Arguin (an extension of the trans-Saharan trade routes), taking captives to be enslaved on Iberian plantations, and exploring along the Senegal and Gambia Rivers in search of sources of gold. These ventures mark some of the earliest attempts at direct European involvement in trans-Saharan trade.
The Portuguese monarchy also hired explorers such as Alvise Cadamosto, a Venetian slaver sent to scout the region of Senegambia. These efforts gave the Portuguese an opportunity to develop a clearer sense of the scope
