What factor resulted in the development of African population beginning in the 17th century?

The transatlantic slave trade, which involved the forced migration of millions of Africans to the Americas to work as enslaved laborers on plantations, resulted in the significant growth of the African population in the 17th century. This mass movement of Africans to the New World led to the establishment of large African diaspora communities in countries such as Brazil, the Caribbean, and the United States.
