The Devşirme System and the Making of the Janissaries

Taken for the Sultan: The Devşirme and the Rise 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.

What Was the Devşirme System?

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, then 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

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. The Janissaries became a closed caste—armed, privileged, tax-exempt, and increasingly uncontrollable.

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 of 1826 Explained

Mahmud II finally destroyed them in the “Auspicious Incident” (Vaka-i Hayriye) on June 15, 1826. 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 in 2026

The devşirme and Janissary system:

• Gave the Ottomans a loyal, professional infantry when most European armies still relied on feudal levies.
• Created a multi-ethnic elite that ruled over a multi-ethnic empire.
• Produced grand viziers, architects, admirals, and poets who shaped Ottoman culture.
• Became a symbol of both Ottoman genius and Ottoman decay.

Today, the word “Janissary” is sometimes used as shorthand for any privileged, conservative military caste that blocks reform. In Turkey, the Auspicious Incident is taught as the moment the empire began modernising. In the Balkans, the devşirme is remembered as child abduction—part of the trauma that still colours relations with Turkey.

The system was cruel, brilliant, and ultimately self-destructive. It gave the Ottomans two centuries of military supremacy, only to become the greatest obstacle to survival in a changing world.

What part of this story stays with you? The cold efficiency of taking boys from their mothers? The way a slave system produced the empire’s greatest statesmen? The moment the Janissaries turned from guardians into parasites? Or the day Mahmud II turned cannon on his own elite troops? Drop whatever is on your mind below. I read every word. Books that shaped how I understand the devşirme & Janissaries:

• The Ottoman Empire, 1300–1650: The Structure of Power by Colin Imber (clear on military organisation)
• Lords of the Horizons by Jason Goodwin (beautifully written chapter on the Janissaries)
• The Janissaries by Godfrey Goodwin (focused study of the corps)
• The Imperial Harem by Leslie P. Peirce (context on palace recruitment & devşirme)
• Osman’s Dream by Caroline Finkel (excellent on early Ottoman military evolution)
