USA HISTORY

Detailed explanation-1: -The English colonies expanded rapidly and the development of a plantation system and the growth of the Atlantic economy brought further demands for African labour. This increased the scale of the trade in enslaved people.

Detailed explanation-2: -The Dutch became the foremost traders of enslaved people during parts of the 1600s, and in the following century English and French merchants controlled about half of the transatlantic slave trade, taking a large percentage of their human cargo from the region of West Africa between the Sénégal and Niger rivers.

Detailed explanation-3: -Where did enslaved Africans come from? In the first 150 years of the trade, West Central Africa supplied nine out of ten African people destined for a life of slavery in the Americas. Except for a fifty-year period between 1676 and 1725, West Central Africa sent more slaves to the Americas than any other region.

Detailed explanation-4: -The transatlantic slave trade began during the 15th century when Portugal, and subsequently other European kingdoms, were finally able to expand overseas and reach Africa. The Portuguese first began to kidnap people from the west coast of Africa and to take those they enslaved back to Europe.
