In Jonathan Edelsteins outstanding timeline Mâle Rising a group of revolting slaves are send to Africa because the brazilian authorities don't want to deal with them. In Africa they build a new state based on republican ideals and ban slavery. What if a group of revolting slaves gets send to West Africa in the 18th century. While I don't think that they would set up a republic they could outlaw slavery because their experience in America. How would a West African state in the 18th century develop if slavery is outlawed and how does this change West Africa if there's a reason to outlaw slavery?
