What were the similarities and differences between the slave trade that was going on within the African continent and the Atlantic slave trade to the Americas?

Both the intra-African slave trade and the Atlantic slave trade involved the capture and forced movement of individuals, primarily for labor. A key similarity was the exploitation of vulnerable populations, often through warfare or social strife. However, the Atlantic slave trade was characterized by its scale and brutality, involving the transatlantic journey known as the Middle Passage, which subjected enslaved individuals to horrific conditions. In contrast, the intra-African trade often involved different systems of servitude, with some individuals retaining certain rights or opportunities for integration into society.
