Final answer:
The transatlantic slave trade greatly impacted African society through depopulation, disrupted trade and societal structures, and the development of African-American cultures in the Americas.
Step-by-step explanation:
Slavery in the Americas had a significant impact on African society. The transatlantic slave trade led to the depopulation of large areas and disrupted trade and societal structures in Africa. Additionally, conflicts among different African tribes and kingdoms for captives to enslave in war created an unstable social and political climate. In terms of cultural impact, while African culture influenced the development of African-American cultures in the Americas, the enslavement process and displacement of millions of Africans caused profound human suffering and challenges that continue to this day.
