Answer:
Traders from Europe went to West Africa and offered cloth, rum, salt, and other goods in exchange for slaves. Many Africans became wealthy by trading slaves for goods like these. In addition to these goods, the European traders also offered to trade guns for slaves.
European trading had a transforming impact on Africa. Europeans poured into Africa enormous volumes of commerce, the whole range of European manufactured goods and hardware, notably firearms, luxury goods (especially alcohol) and transhipped items from Asia (particularly textiles).
They began to kidnap people from the west coast of Africa.The Spanish took the first African captives to the Americas from Europe as early as 1503, and by 1518 the first captives were shipped directly from Africa to America. The majority of African captives were exported from the coast of West Africa, some 3,000 miles between what is now Senegal and Angola, and mostly from the modern Benin, Nigeria and Cameroon.
