That does not include the Barbary–Moroccan trade in western Europeans nor the several million Serbs and Albanians enslaved by the Ottomans: some of these enslaved children became viziers and valide sultans, but that does not diminish their tragedy. Many Islamic slaves were females who served in households – but domestic service almost always included sexual abuse. It is estimated that the Crimean khans alone enslaved four million. Since there is no paperwork whatsoever for any of these trades, it is likely they are grossly underestimated.
