Allegiances are volatile no doubt, but the Kurds want independence from the Turks. Also be aware that Christians also fought for the Turks against other Christians and were known as Janissaries. What do we do about their descendants?
Turkish administrators would scour their regions (but especially the Balkans) every five years for the strongest sons of the sultan's Christian subjects. These boys (usually between the ages of 6 and 14) were then taken from their parents and given to Turkish families in the provinces to learn Turkish language and customs, and the rules of Islam. The recruits were indoctrinated into Islam, forced into circumcision and supervised 24 hours a day by eunuchs.
