Africans were never brought to the Western Hemisphere for slavery.

What if for whatever reason/cause blacks were never brought to North or South America for slavery or anything? They were totally left in Africa. What effect would that have had? What would racial relations be like in THE WORLD?
 
Long story short: depends very much on why they weren't brought over. Did they unify and become to strong to easily pluck out? Did the Westerners get mechanized harvesters? Did a sweeping wave of abolitionism rise in Europe? All the scenarios have very different outcomes.
 
The first possibility seems most interesting....but those larger Empires that did arise were themselves slaver states. That poses a problem.
 
Unfortunately, abolitionism can never gain any traction until slavery becomes economically unviable :(. That would require dramatically sped-up technological and economic development in Europe, which may not be possible without American resources. Even if the European kingdoms had all banned slavery (and as IIRC it had almost disappeared there that might be conceivable), I doubt such laws would be enforced outside Europe. You'd have to either posit stronger, stable states in West Africa or that the extractive plantation colonial system never be established.

Of course, if West Africa has strong, stable states, the slave traders would probably just get their slaves from somewhere else, probably from East Africa through the Arabs. Native American mass slavery is not an option due to disease.
