Devshirme Recruitment System

Timeline

1. c. 1383–1400Early Ottoman Balkan territories · Balkan PeninsulaUnder Sultan Murad I, the Ottoman Empire began forcibly conscripting boys from conquered Christian subject families, training them in Islam and incorporating them into the palace and Janissary corps, forming the initial framework of the devshirme system.
2. 1400–1451Ottoman Balkan provinces · Balkan PeninsulaIn the early 15th century the scale of recruitment gradually expanded, mainly targeting rural Christian boys in the Balkans, usually aged 8 to 20. Selected boys were sent to the palace school in Istanbul (Enderun Mektebi) for Islamic education, Ottoman Turkish, and military or administrative training; the best rose to high imperial office, the rest joined the Janissary corps.
3. 1451–1481Constantinople · Ottoman EmpireMehmed II himself was trained through the palace school system and understood the value of the recruitment system. During his reign recruitment reached its peak, and most of the Janissary elite used in the 1453 conquest of Constantinople were devshirme in origin. The sultan appointed many devshirme-origin men to the highest administrative posts such as grand vizier, balancing the traditional Turkish nobility and strengthening centralization.
4. 1600–1648Ottoman Empire · Ottoman EmpireFrom the 17th century, Janissary corruption worsened, Muslim sons began to be mixed into the recruitment pool, and the system's operation gradually became lax and formalized. With increasing imperial fiscal and military pressures, regular devshirme recruitment had in fact ceased, and the system was declared ended around the reign of Mehmed IV.
