These two islands, located off West Africa and in the Gulf of Guinea, became leading centers of world sugar production and plantation slavery from the mid-1400s to the mid-1500s. Portuguese merchants dominated this early trade.
Much of the earliest European trade with West Africa, however, was in gold, not people. Europeans did not have the power to overcome African states before the late 19th century, and gold production, centered in Akan gold fields in the backcountry of present-day Ghana, remained in African hands. Europeans called this region the Gold Coast. Agreements between African and European elites and rivalries for the African gold trade resulted in the construction of dozens of trading forts, or stone castles, along a 161 km (100 mi) coastal stretch of Ghana. Several of these forts survive, have been repaired by the government of Ghana, and are tourist attractions today. It was not until the late 17th century that the value of European goods traded for African people surpassed the value of goods exchanged for gold. Over time, these gold forts became slave forts, where hundreds of Africans were confined in prisons awaiting sale and shipment.
THE SLAVE TRADE AND DEVELOPMENT OF PLANTATIONS IN THE AMERICAS .
Christopher Columbus's "discovery" of the New World in 1492 marked the beginning of a transatlantic trading system. Via the slave trade, Africans played a leading role in the creation and evolution of this large and long-lasting "Atlantic system." Spanish adventurers arrived in the Americas hoping to trade for riches but soon enslaved the Native American peoples in their search for gold and silver. Disease, malnutrition, and Spanish atrocities led to the deaths of millions of the Indians of the Americas. By the 1520s the depopulation of the region prompted the Spanish government to look for alternative sources of labor. Officials contracted with Portuguese merchants to deliver Africans to Spanish territories in the New World.
