The Scientific Revolution (SR) developed a powerful influence among educated people in the sixteenth and seventeenth centuries. Despite the fact that superstitions remained common and the witch craze emerged in the same era, educated elites increasingly became interested in natural philosophy (science). WHAT WERE THE KEY ATTRIBUTES OF THE SCIENTIFIC REVOLUTION? WHAT ROLE DID THE SCIENTIFIC METHOD PLAY? West Africans had traded with Europeans through merchants in North Africa for centuries. The first traders to sail down the West African coast were the Portuguese in the fifteenth century. Later the Dutch, British, French and Scandinavians followed. They were mainly interested in precious items such as gold, ivory and spices, particularly pepper. From their first contacts, European traders kidnapped and bought Africans for sale in Europe. However, it was not until the 17th century, when plantation owners wanted more and more slaves to satisfy the increasing demand for sugar in Europe, that transatlantic slaving became the dominant trade. The Trans-Atlantic Slave Trade did not invent slavery. Slavery has existed for millennia and slavery already existed in sub-Saharan Africa before it. IN WHAT WAYS WAS THIS NEW SLAVE TRADE NEW, WITH WHAT INFLUENCES ON THE AFRICANS BOTH IN AFRICA AND IN OTHER PLACES?
