Can there be a black King of England?
I saw this questioned asked and the answer is there have beem several Black Kings and Queens of England.

Ethnic and genealogical factors where what made a king long ago not the color of the skin
The northern Europeans brought the color factor into the thinking of the world.

Keep in mind that there is history and there is factual/real history
Also the current ruling family where not from England
The Moors/Blacks from Africa had conquered most of Europe and ruled there for several hunderd years. They had rulers and married into ruling families.

One such was the STUARTS (had Moors/Black blood in them).

The word Stuart comes from the old nordish root Svart which means black. Stuart is the same word as Swarthy, which means black in old English.

There was once a Stuart line of Kings in England. The name of the founding ancestor was Stuart which means Black man.

Stuart Kings of England and Scotland, King Charles II, also lovingly known as the “black boy” of England by his subjects. He is commemorated in the celebrated name of the Black Boy Inn, found all over the British Isle.
