White people never "enslaved" the jigs. At best, there were a few, at the start of the trips in Africa, incidents of capturing "locals", but this was mostly for scientific inquiry. It was Arabs and other tribes who did the "enslaving". One tribe would go to war with another tribe, the winners would sell the losers into slavery. Also, if you look into "Modern Slavery" cases, there's a lot of Africans still up to that.
Nigeria has Boko Haram, who kidnap school girls. For balance Uganda has the LRA, it's own crazy religious terrorist group.
Bongland has been importing them since the late 40s. Some of the Afro Cab islands had a problem with young unemployed men, and wanted to dump them in the UK. Plus, there is still the "Commonwealth". But that does include "white countries" like Maplelandia (they have a part that speaks Frog), and The Down Unders (Ex Prison colony, say no more).
Also, some American muso's have moved to Europe, to escape the "buggerotry" of the States. This usually means junkies moving to France (J Baker, J Baldwin and N Simone), but "Champion" Jack Dupree decided to move to the Norf, in the 60s.
I think Fred "The Hammer" Williamson was the exception, he ended up in Rome. Making movies. Vatican has some very nice tax relief plans, I hear.
