Majority African-descended country/enclave in Eurasia (pre-1900 of course)

Well, various areas in the Americas became African-descended majority, due to the Atlantic slave trade. Granted, the destination for agriculture in relatively low density areas in the Americas can be different from Europe, and Europe didn't ever seem to have a large population of African slaves within Europe. But maybe something could have happened, like with Italian merchant republics trying to establish plantations in the Aegean or Crimea?

Axum/Ethiopia in Arabia also sounds possible.

As for Portugal and Cabo Verde, maybe in a bit of a different direction, something with Lusotropicanism? Perhaps a scenario where the United Kingdom of Portugal, Brazil, and the Algarves survives can be one where migration from Brazil and the African colonies (which perhaps themselves end up integrated into the political system) leads to gradual migration patterns that leave mainland European Portugal at least minority-majority with African and mixed populations together outnumbering the white population, perhaps with some opposition at least for a time from the European Portuguese, but with European Portugal increasingly dominated by a Brazil that doesn't really care.

This would probably be more unrealistic, and is outside the bounds of the OP, but maybe if the 1975 Carnation Revolution went differently, a radical leftist Portugal might seek to integrate the colonies and integrate FRELIMO, MPLA, and PAIGC into the revolutionary government. Then, a mixture of migration from Africa to Portugal and vice versa, as well as intermarriage and such, and perhaps some refugees from various African and Middle Eastern Wars in the 1990s and 2000s, could lead to an African majority some time in the 21st century, if the revolutionary regime isn't overthrown.
 
Maybe some kind of Trinidad/Dubai situation, where workers get brought over to some affluent polity to do work for cheaper than Europeans would, and over time make up the majority?
 
Have Russia establish a foothold in Africa via becoming more involved in the construction of the Suez Canal during the 1830s, paving the way for Russia to establish a colony encompassing Eritrea and Djibouti while slowly transforming Ethiopia into a protectorate. Over time, Ethiopian immigration to Russia begins to pick up and sees an Ethiopian majority form somewhere in European Russia by the time the First World War comes around - depending on what happens from then, you might see said enclave grow or decline.
I doubt Russia would be keen on setting up colonies.
 
How about Sicily? With the right kind of circumstances Sicily would be a good place to have a nation. It is not far from Tunisia.

Background - parts of Sicily was controlled by Carthaginian states. But let us jump ahead to the Muslim expansion in the 2nd and 3rd century = there was attempts to land and colonize the island and attempts at conversion, most of these attempts would finally fail with the coming of the Normans.

If Sicily was ruled by North Africans and more culturally similar to them (doesn't matter if they're Carthaginian, some neo-Roman state in Carthage, Berber, or Arab), I wouldn't be surprised if it ended up being considered part of North Africa. Like Crete or the Baleares, it's very possible but ultimately it's shifting the definitions a bit.

On the other hand, there might be something more true to OP where you could have a slave revolt (of black Africans) in North Africa (including Malta) where the slaves win in Malta but lose on the mainland, yet are still able to flee to Malta. If they kill enough of the people there, you now easily have a "Mediterranean Haiti".
 
Is it possible for Europeans to do plantation agriculture somewhere in Asia, and bring in enough African slaves that we end up with a Caribbean style country? Or are there just not any areas in Asia with the right climate and a low enough population to be outnumbered by the slaves?
 
I'm still for Cabo Verde just being made a province but here's some other takes:

But you could also just make all of Macaronesia (Azores, Madeira, Canaries and Cabo Verde) be under the realm of one colonial power

be populated almost entirely by Euro-Africans (genetically and/or culturally)

Have the island chain population migrating to a weakened mainland sometime in the mid to late 19th century swamping out a particular region or major city.
_____
Maybe the islands after the initial slave trade ends has a formalizedformaliz of legitimizing mixed race heirs who's sugar and tropical goods wealth leads them to develop institutions of higher learning and a skilled work force that dominates Amsterdam or another coastal European trade city
_____
Maybe if it's early enough a war torntorn weak Metropole gets into another battle but this one being an independence war with the islands and is forced to recognize the islands as a nation.

Through wealth, skilled workers, cultural history and maybe some marriages of daughters of prominent men to European minor nobility or major merchant families is recognized by Europeans as a independent European nation by the late 19th century.
 
Anywhere in Arab Peninsula, Mesopotamia or Turkey it could be possible. One Iraq City has/had a population partly descandet from West African populations. They even maintained local traditions. u
 
Make Oman more Swahili, if it wasn't for the Swahili educated in the U.K. and Europe the nation wouldn't have been able to modernize. Its the whole reason why Qaboos (himself being partially of african descent through his great grandfather who was at least 3/4th Suri) asked them to return to build up the nation.

To this day they basically are the glue of high government and industry.

Make the migration call earlier and add the western educated elites in the mid 20th century and you'll have a majority African nation with them not being at the bottom of the hierarchy.
