In the Ottoman Empire, some important positions occupied by slaves

The Ottoman Empire was very popular devşirme - the custom to take boys from non-Muslim families to raise their exemplary Muslims and slaves of the Sultan. The main objective was the selection and training of the most talented children to senior positions such as commanders, courtiers and lords - so they can effectively serve the Empire.

The ideal candidate's age to work (more on the kidnapping) was considered the period from 10 to 20 years, although often taken boys and younger. In some cases, parents have attempted resistance - for example, mutilated their sons, so that no one wanted to take.

Despite the fact that the young man received recognition and wealth in their new life, they are still considered to be the slaves of the "true" Muslims. They themselves, as well as their wives, children and property were considered the property of gentlemen thieves.
