White Gold by Giles Milton
'White Gold, is the story of Thomas Pellow, a Cornish cabin boy who was captured at sea by a group of fanatical Islamic slave traders—the Barbary corsairs, taken in chains to the great slave markets of Algiers, Tunis and Salè in Morocco and sold to the highest bidder. Pellow’s purchaser happened to be the tyrannical sultan of Morroco, Moulay Ismail, a man committed to building a vast imperial pleasure palace of unsurpassable splendour built entirely by Christian slave labour. After enduring long periods of torture Pellow converted to Islam and became the personal slave of the sultan for over two decades—including a stint as a soldier in the sultan’s army—before finally making a dramatic escape and return to Cornwall.'

Granted. Because Caucasians have the fairest skin, eye and hair pigmentation they are the gold standard.
edit: sometimes though that's a distinct disadvantage.
