yeniçeri

Janissary comes from Turkish yeniçeri, a compound of yeni ('new') and çeri ('soldier, warrior'). The word named the Janissary corps (Ocak, literally 'hearth'), the elite infantry and household troops of the Ottoman sultans, established in the late fourteenth century under Murad I. The 'new soldiers' were so called to distinguish them from the older Turkic cavalry and irregular forces — they were a new kind of Ottoman military institution: professional, salaried, trained from youth, loyal directly to the sultan rather than to tribal or feudal lords. Their recruitment came from the devşirme system, the periodic levy of young boys from Christian families in the Balkans and Anatolia. These boys were brought to Istanbul, converted to Islam, educated at the palace, and trained for military or administrative service. They had no family in the ordinary sense — the Ottoman state was their only allegiance.

The Janissaries were, for centuries, among the most effective infantry forces in the world. They were among the first regular troops in Europe to adopt firearms as a primary weapon, and their discipline, training, and cohesion gave the Ottoman armies a tactical advantage that European and Asian opponents struggled to match. The conquest of Constantinople in 1453, the expansion into Egypt, the Safavid campaigns, the siege of Vienna in 1529 — in all of these, the Janissary corps was the sharpest instrument of Ottoman military power. Their distinctive white felt caps (börk), their musical corps (mehter) with its cymbals, drums, and shawms, their military discipline — all were recognizable and feared across the known world. Mehter music influenced European military band music so deeply that traces of it survive in every marching band today.

The Janissaries' political evolution mirrors the pattern of many elite institutions: from loyal servants of the state to power brokers within it. As the corps grew in size and political consciousness, and as the devşirme system weakened and Janissaries began admitting their own sons, the corps became a hereditary military caste with its own interests to defend. From the late sixteenth century onward, Janissaries intervened repeatedly in Ottoman politics — deposing sultans who threatened their privileges, installing more pliable rulers, and resisting military reforms that would have reduced their importance. Between 1566 and 1789, they deposed or murdered at least six sultans. The 'new soldiers' had become the kingmakers of the Ottoman system, their loyalty to the sultan conditional on the sultan's loyalty to their interests.

The Janissaries were eliminated in 1826 by Sultan Mahmud II in an event called the Auspicious Incident (Vaka-i Hayriye). When the Janissaries mutinied against a new Western-style army that Mahmud was establishing, he turned artillery on their barracks in Istanbul, killed thousands, disbanded the corps, and destroyed its institutions. The centuries-old hearths were extinguished. 'Janissary' passed into European languages already carrying its complex history: a word that meant elite soldier but also zealot, a word for a devoted follower who could become a usurper. In English it had acquired by the nineteenth century the sense of a fanatical partisan, a loyal supporter of dangerous powers — a meaning that the actual history of the corps, with its institutionalized loyalty and institutionalized rebellion, more than justifies.
