The Devşirme System and the Making of the Janissaries

Hey timeline kin, walk into the courtyard of the Topkapı Palace at dawn in the mid-15th century. The air still carries the chill of night. A line of boys, some as young as eight, some already sprouting beards, stands barefoot on the cold marble.

They come from Christian villages in the Balkans: a shepherd’s son from Bosnia, a fisherman’s boy from Albania, a woodcutter’s child from Serbia. Their heads are shaved, their clothes are the rough wool they wore when Ottoman raiders or local Christian lords handed them over. They are frightened, silent, eyes wide. A tall officer in a white felt cap walks the line, lifting chins, checking teeth, and feeling shoulders for strength. He is not cruel; he is appraising. These children are not prisoners of war. They are not slaves in the ordinary sense. They are the devşirme, “the gathered ones,” and in a few years, most of them will become Janissaries: the elite infantry corps that will make Europe tremble and keep sultans on their thrones.

This is not a fairy tale of upward mobility dressed in romantic colours. It is a system that was both horrifyingly efficient and strangely intimate: the Ottoman state took Christian boys from their families, raised them as Muslims in the imperial household, trained them to absolute loyalty, and turned them into the most feared professional soldiers in the early modern world. For more than three centuries (roughly 1360s–1826), the Janissaries were the beating heart of Ottoman military power—and eventually one of the main reasons the empire struggled to modernise. Let’s walk through how the devşirme worked, how the Janissary corps was born and grew, why it was so effective for so long, and why it finally became a monster that had to be killed by its own sultan.

The Devshirme system was one of the most controversial institutions of the Ottoman Empire, creating the elite Janissaries who dominated warfare from the 15th to 17th centuries.

What Was the Devshirme System in the Ottoman Empire?

The devşirme (“collection” or “gathering”) was the Ottoman practice of periodically levying Christian boys from rural villages in the Balkans and Anatolia, converting them to Islam, and enrolling them in the kapıkulu (“slaves of the Porte”), the sultan’s personal military and administrative elite. It began informally under Murad I (r. 1362–1389) as a means of creating a loyal bodyguard unit free from tribal or aristocratic ties. By the reign of Murad II or Mehmed II, it became a formal, regulated levy. The rules were strict:

• Only Christian boys (never Muslims or Jews—the levy was religiously targeted).
• Ages roughly 8–18 (young enough to be reshaped, old enough to survive the journey).
• One boy in every forty households in a district (sometimes one in twenty during emergencies).
• No only sons, no boys whose families would starve without them.

The boys were marched to Istanbul or Edirne, inspected, circumcised, given Muslim names, and sent to Turkish peasant families in Anatolia to learn language and Islam. The brightest and strongest were selected for the Enderun (Inner Palace School) or for direct entry into Janissary training. The rest went to agricultural labour or other kapıkulu units.

How the Janissaries Became Europe’s First Standing Army

The Janissaries (Yeniçeri = “new troops”) began as a bodyguard unit for Murad I. Under Mehmed II (the Conqueror), they became a standing army of 10,000–15,000 men. During Süleyman the Magnificent’s reign (1520–1566), their number reached 40,000–50,000. Training was monastic in its intensity:

• Years of drilling in the use of the arquebuses, sword, bow, and sabre.
• Constant physical exercise, wrestling, archery on horseback.
• Strict discipline: no marriage allowed until retirement (later relaxed), no private trade, no beards (to distinguish them from civilians).
• A code of loyalty: the sultan was their “father,” the corps their “family.”

They lived in barracks, ate from communal kitchens (the famous “spoon brothers” tradition, each unit had a giant cauldron as its symbol), and were paid regular salaries plus booty. They wore distinctive white felt caps (börk) with a wooden spoon tucked in the front. They were armed with the latest gunpowder weapons, arquebuses, matchlocks, and muskets, and became the first standing infantry corps in Europe to rely primarily on firearms.

Their battlefield reputation was terrifying. They fought on the front lines at Mohács (1526), Vienna (1529), Malta (1565), Lepanto (1571), and in countless smaller engagements. European observers described them as fearless, disciplined, almost fanatical. They were not invincible. Lepanto was a major naval defeat, but on land, they were the backbone of Ottoman supremacy for two centuries.

Why the Janissaries Declined and Became a Threat to the Ottoman Empire

By the late 16th century, the corps began to change. Marriage was allowed (1566 onward). They began enrolling their own sons, turning the corps hereditary instead of merit-based. Devşirme levies became irregular and eventually stopped altogether by the mid-17th century. By the 17th century, the Janissaries had transformed from a merit-based elite into a hereditary caste, weakening the military strength of the Ottoman Empire.

They deposed sultans (Osman II in 1622, Mustafa IV in 1808), extorted money from the treasury, ran protection rackets in Istanbul, and blocked military reforms. Attempts to modernise the army (Nizam-ı Cedid under Selim III) were crushed by Janissary revolts. By the early 19th century, they were more a political mafia than an effective fighting force.

The Auspicious Incident (1826): How Sultan Mahmud II Destroyed the Janissaries

Mahmud II ended the power of the Janissaries during the Auspicious Incident, marking a turning point in Ottoman military reform. He lured the Janissaries into the Hippodrome, then bombarded them with artillery. Between 4,000 and 10,000 were killed in a single day. The corps was abolished, the barracks burned, and the sultan declared the end of the old order.

The massacre was brutal but calculated. Mahmud had spent years building a new artillery corps loyal only to him. He provoked the Janissaries into open revolt, then crushed them with modern weapons. The event marked the end of the devşirme-Janissary system and the beginning of serious Ottoman modernisation.

Legacy of the Devshirme System and Janissaries in 2026

The Devshirme system and the rise of the Janissaries were central to the long-term success of the Ottoman Empire. From the 14th to the 17th century, this system helped transform the Ottomans into one of the most powerful empires in the world.

At its peak, the system delivered several strategic advantages:

• It created a loyal, professional standing army at a time when most European states still depended on feudal levies and temporary mercenaries.
• It built a multi-ethnic ruling elite, integrating Balkan, Anatolian, and other regional populations into a single imperial structure.
• It produced not only soldiers, but also top administrators and cultural figures, including grand viziers, naval commanders, architects, and court scholars who shaped Ottoman governance and identity.
• It became a defining symbol of Ottoman statecraft—representing both institutional brilliance and long-term structural risk.

However, by the 17th and 18th centuries, the same system began to undermine the empire. The Janissaries evolved into a hereditary and politically powerful class that resisted reform, weakened military effectiveness, and interfered in imperial governance. This decline culminated in the decisive intervention of Mahmud II during the Auspicious Incident, when the Janissary corps was violently abolished to allow modernization of the Ottoman military.

In modern historical memory, interpretations of the system remain deeply divided. In Turkey, the destruction of the Janissaries in 1826 is often viewed as a necessary turning point toward modernization and centralization. In contrast, across the Balkans, the Devshirme system is widely remembered as a form of forced child recruitment, contributing to long-lasting cultural and historical trauma.

Today, the term “Janissary” is sometimes used more broadly to describe a privileged, conservative military or political elite that resists institutional reform. This reflects the enduring legacy of the system as both a model of early state efficiency and a cautionary example of how elite institutions can become obstacles to progress.

Ultimately, the devshirme–Janissary system was one of the most complex institutions of the early modern world—a mechanism that built imperial power through discipline and loyalty, but also sowed the seeds of its own decline.
