How was slavery that existed in Africa different for the the transatlantic slave trade?

Slavery in Africa prior to the transatlantic slave trade often involved various forms of servitude, including debt bondage and war captives, where enslaved individuals could sometimes integrate into their captors' societies, marrying and retaining some rights. In contrast, the transatlantic slave trade commodified human beings on a massive scale, forcibly removing millions from their homelands, subjecting them to brutal conditions, and treating them as property without rights. The latter was characterized by a racialized system that dehumanized enslaved individuals, leading to generational enslavement and a legacy of systemic racism. Thus, while both systems involved exploitation, the transatlantic slave trade was marked by its extreme brutality and the scale of human suffering involved.
