Suppose the sub-Saharan Africans traveled north, conquered somewhere in Europe, ruling as a minority elite (like, e.g., the Vikings in various places). Then, some time later--50 years? 100? 150?--there is a mostly successful rebellion against them. (Maybe similar to the Reconquista, but sooner and happening faster.) Not enough time has passed for them to be mestizoed.
Instead of packing up and returning to Africa, they form a garrison state in the mountains, or maybe an island or part of a coastal region, concentrated in a fairly small area, outnumbering the non-African locals.
Another possible factor: What if, before they lose control of the larger territory, something happens to make them doubt the loyalty of the non-African part of their armed forces? (Like a rebellion, or coup attempt or something--even if it's only some of them doing it.) Then the Africans could encourage more people from their tribe/original nation to migrate to Europe--maybe offer good pay, land/mansions, honors, perks like that. So when they lose the rebellion, there's more Africans to form the garrison state.
