Wrong again my uneducated arrogant buddy!!!! Mamelukes had NOTHING to do with Europe! Again you show that you have pretty much no knlowledge of history whatsoever. You have been exposed to some form of racist pan-African crusade and whatever has not been explained to you, you conveniently fill in the gaps by yourself.
That might work out fine in your own world but for others, that is a different story.

Mamelukes were also refered to as Circassians, in other words people from the northern part of the Caucasus, lying on the military border of Islam (and hence subject to being raided, murdered and enslaved according to Islam. People from the northern part of the Caucasus are also white (hence the term Caucasians).

The muslims from Europe have no relation whatsoever to your fantasy people. The Ottomans had a special human tax which called to all Christian villages and towns to give up one fifth of their sons in slavery, up to the age of five. These were then delivered to the Sultan before being eudcated in Islamic fashion and later trained in the famed janissary corps.

The remnant of the white muslim population is simply descended frmo the native people of the Balkans, including Slavs who converted to Islam over the centuries, in order to be releaved from the Jyzzya tax. Do I have to do all the research for you???
