Lust For Gold

When the Portuguese first sailed down the Atlantic coast of Africa in the 1430's, they were interested in one thing. Surprisingly, given modern perspectives, it was not enslaved people but gold. Ever since Mansa Musa, the king of Mali, made his pilgrimage to Mecca in 1325, with 500 enslaved people and 100 camels (each carrying gold) the region had become synonymous with such wealth. There was one major problem: trade from sub-Saharan Africa was controlled by the Islamic Empire which stretched along Africa's northern coast. Muslim trade routes across the Sahara, which had existed for centuries, involved salt, kola, textiles, fish, grain, and enslaved people.

As the Portuguese extended their influence around the coast, Mauritania, Senagambia (by 1445) and Guinea, they created trading posts. Rather than becoming direct competitors to the Muslim merchants, the expanding market opportunities in Europe and the Mediterranean resulted in increased trade across the Sahara. In addition, the Portuguese merchants gained access to the interior via the Senegal and Gambia rivers which bisected long-standing trans-Saharan routes.

Beginning to Trade

The Portuguese brought in copper ware, cloth, tools, wine and horses. (Trade goods soon included arms and ammunition.) In exchange, the Portuguese received gold (transported from mines of the Akan deposits), pepper (a trade which lasted until Vasco da Gama reached India in 1498) and ivory.

Shipping Enslaved People for the Islamic Market

There was a very small market for enslaved Africans as domestic workers in Europe, and as workers on the sugar plantations of the Mediterranean. However, the Portuguese found they could make considerable amounts of gold transporting enslaved people from one trading post to another, along the Atlantic coast of Africa. Muslim merchants had an insatiable appetite for enslaved people, which were used as porters on the trans-Saharan routes (with a high mortality rate), and for sale in the Islamic Empire.

Start of the Trans-Atlantic Trade of Enslaved People

By-Passing the Muslims

The Portuguese found Muslim merchants entrenched along the African coast as far as the Bight of Benin. This coast was reached by the Portuguese at the start of the 1470's. It was not until they reached the Kongo coast in the 1480's that they outdistanced Muslim trading territory.

The first of the major European trading 'forts', Elmina, was founded on the Gold Coast in 1482. Elmina (originally known as Sao Jorge de Mina) was modeled on the Castello de Sao Jorge, the first of the Portuguese Royal residence in Lisbon. Elmina, which of course, means the mine, became a major trading center for enslaved people purchased along the rivers of Benin.

By the beginning of the colonial era there were forty such forts operating along the coast. Rather than being icons of colonial domination, the forts acted as trading posts - they rarely saw military action - the fortifications were important, however, when arms and ammunition were being stored prior to trade.

Market Opportunities for Enslaved People on Plantations

The end of the fifteenth century was marked (for Europe) by Vasco da Gama's successful voyage to India and the establishment of sugar plantations on Madeira, Canary, and Cape Verde Islands. Rather than trading enslaved people back to Muslim merchants, there was an emerging market for agricultural workers on the plantations. By 1500 the Portuguese had transported approximately 81,000 enslaved Africans to these various markets.

The era of European trading of enslaved people was about to begin.
