Introduction
The Devshirme system and the Janissary corps formed the backbone of the Ottoman military machine. Together, they shaped conquest, imperial control, and the maintenance of absolutist power.
The Devshirme System
The Devshirme (literally “collection”) was a levy imposed on Christian populations within the Ottoman Empire, particularly in the Balkans, from the late fourteenth century onwards.
Devshirme: A system by which the Ottoman state recruited Christian boys from subject territories, converting them to Islam and training them for military or administrative service.
Purpose and Recruitment
Designed to provide the Sultan with loyal servants entirely dependent on his favour.
Boys, usually between 8–18 years old, were taken from Christian families at regular intervals.
They were forbidden contact with their families and communities after recruitment.
Recruits were converted to Islam and educated rigorously in language, religion, and military skills.
The system deliberately severed familial ties, creating a cadre of state slaves (kul) who owed loyalty only to the Sultan.
Training and Allocation
The most talented recruits were channelled into the Palace School (Enderun), where they could rise to become high officials, viziers, or court advisors.
The majority became soldiers, forming the elite Janissary corps.
Others entered administrative and technical services, supporting the functioning of the Ottoman state.
The Devshirme provided a continuous pipeline of skilled personnel that fused military, political, and administrative roles.
The Janissary Corps
The Janissaries (Yeniçeri, “new soldiers”) emerged as the Ottoman Empire’s first standing infantry force, distinct from the feudal cavalry tradition.

Janissaries: An elite corps of infantry soldiers, drawn primarily from Devshirme recruits, trained to serve as the Sultan’s household troops and central army.
Characteristics and Organisation
Disciplined and professional: Unlike feudal levies, they were salaried soldiers, permanently maintained by the state.
Uniform and equipment: Known for their distinctive uniforms, strict codes of conduct, and use of firearms by the sixteenth century.
Hierarchy: Structured into regiments and companies under central command, answering directly to the Sultan.
Privileges: Received regular pay, rations, and pensions, reflecting their importance.
The Janissaries functioned as the Sultan’s praetorian guard and were housed within barracks near Constantinople, reinforcing their role as guardians of both ruler and state.
Role in Conquest
The Janissaries played a central role in the rapid expansion of the Ottoman Empire:
At the Fall of Constantinople (1453), they led assaults with discipline and advanced artillery coordination.
In Balkan campaigns, they ensured Ottoman supremacy through shock tactics and sustained pressure.
Against European opponents, their early adoption of gunpowder weapons gave the empire a decisive edge.
Their effectiveness underpinned Ottoman dominance from the fifteenth to early sixteenth centuries.
Firearms training, especially with the arquebus and later musket, reinforced the corps’ reputation for volley fire, siege work and urban assault.

The Army and Military Tradition
Integration of Systems
The Devshirme and Janissaries represented the fusion of religious duty, military professionalism, and state power.
Recruitment was justified under Islamic law as a form of tax on non-Muslim populations.
Their service embodied both jihad-inspired expansion and absolutist centralisation.
Discipline and Loyalty
Rigorous training and surveillance curtailed corruption and dissent in the early centuries.
Absolute obedience to the Sultan was emphasised, with punishments for disobedience being severe.
Their presence at court reinforced the Sultan’s absolutism and provided a counterbalance to the feudal aristocracy.
Broader Military Role
The Janissaries formed the core infantry, complemented by cavalry sipahis supported through the timar system.
They garrisoned key fortresses and acted as shock troops in major campaigns.
As a permanent, centralised military force, they ensured the empire’s cohesion over diverse and far-flung territories.
Limits and Challenges
Though initially effective, the system carried inherent weaknesses:
Over time, the Janissaries’ privileges grew, leading to resistance against reform.
By the late sixteenth century, the hereditary entry of sons of Janissaries undermined the original Devshirme ethos of loyalty and meritocracy.
Their political interference increased, often influencing succession disputes or rebelling when dissatisfied.
Despite these later flaws, in the period 1453–1606, the Devshirme and Janissary system was crucial for sustaining conquest, control, and absolutist power, exactly as the OCR specification emphasises.
FAQ
Reactions varied. Some families saw the levy as devastating, losing sons to the Sultan’s service. Others viewed it as an opportunity for advancement, since successful recruits could rise to high positions in the Ottoman hierarchy.
Local Christian leaders often protested against the practice, but resistance was limited due to the empire’s overwhelming power. Oral traditions and folk songs reflect a mixture of fear, resentment, and reluctant acceptance.
The ban on marriage was designed to ensure complete loyalty to the Sultan and prevent the formation of hereditary power bases.
By remaining unmarried, Janissaries were expected to dedicate their entire lives to service, maintaining discipline and focus on military duties.
This restriction gradually weakened in the late sixteenth century, contributing to the decline in their effectiveness and discipline.
After recruitment, boys were converted to Islam and given rigorous religious education. This created a shared cultural and ideological identity within the corps.
Key aspects included:
Memorisation of Quranic passages.
Instruction in Islamic law and values of obedience.
Integration into rituals and practices that reinforced loyalty to the Sultan as both political and religious leader.
This training underpinned the idea of service as both a political duty and a religious act.
Recruitment: Janissaries came through the Devshirme, while sipahis were granted land (timars) in exchange for service.
Payment: Janissaries were salaried; sipahis relied on tax revenues from their land grants.
Function: Janissaries acted as elite infantry, often stationed in garrisons and siege forces, while sipahis provided mobile cavalry support.
Together, these groups complemented one another, ensuring balance between centralised control and provincial military obligations.
Several factors contributed:
Growing resentment among Christian communities made recruitment harder.
Corruption allowed Muslim families and Janissary sons to enter illegally, undermining the system’s original purpose.
The empire shifted towards other recruitment and payment models, such as contracted mercenaries.
The decline of the Devshirme marked the erosion of the tightly controlled military-administrative structure that had supported Ottoman absolutism in its earlier period.
