I want to know the answer to the following question:
What was the name of the boarding school for Christians during the Ottoman Caliphate?
All the background I'm provided with is that "The second track was a free boarding school for the Christians, the Enderûn, which recruited 3,000 students annually from Christian boys between eight and twenty years old from one in forty families among the communities settled in Rumelia or the Balkans, a process known as Devshirme (Devşirme).". Is that enough to answer the question?
