The document discusses how the trans-Atlantic slave trade negatively impacted Africa socially, politically, economically, and culturally. It robbed Africa of its human resources, destroying the labor force and straining the economy. It increased conflicts as African groups captured their own people for the Europeans. Over time it led to the loss of many cultural practices and the formation of new languages. Politically it contributed to instability as weapons were distributed and alliances formed around the slave trade. Some African kings grew powerful from it, but the capturing of slaves was usually violent.
