Final answer:
The African slave trade involved the forcible movement of millions of African slaves overseas and altered the nature of society in Africa.
Step-by-step explanation:

Europe's age of exploration in the fifteenth century led to an increased demand for labor in the New World, resulting in the enslavement of Africans. This trade altered the nature of society in Africa and had a significant impact on the lives of those involved.
