Janissary Corps (Guard Infantry)

Timeline

1. c. 1363–1400Edirne (Adrianople), Ottoman capital · ThraceThe Janissary Corps was established during Murad I's reign, initially staffed with war captives, later developing into the devşirme system: each year boys were recruited from Balkan Christian families, sent to Turkish households for Islamic education, then entered barracks training. Soldiers served for life, were forbidden to marry (in the early rules), and were directly loyal to the sultan, forming the Ottoman Empire's most reliable core fighting force.
2. 1453Walls of Constantinople · ConstantinopleIn the 1453 siege of Constantinople, the Janissaries were the elite Ottoman infantry. Before the general assault on May 29, irregular troops had repeatedly charged to wear down the defenders; the Janissaries then entered the breach in relatively orderly formation. Later legend holds that Ulubatlı Hasan was the first to scale the wall and plant the flag—a narrative tradition rather than independently verifiable contemporary fact. Mehmed II entered the city, and the Eastern Roman Empire fell.
3. 1453–1566Ottoman battlefields · North AfricaFrom Mehmed II to Suleiman I, the Janissary establishment gradually expanded from a few thousand (recorded at about 7,841 in 1484 and about 13,599 in 1574). Firearms (tüfenk) were already fairly widely issued during Murad II's reign (1421–1451, with interruptions), making the corps one of the earliest standing infantries in Eurasia to use firearms on a large scale.
4. 1826Istanbul · IstanbulIn the 17th–18th centuries the Janissaries gradually became corrupt and repeatedly intervened in depositions and enthronements. On June 15, 1826, Sultan Mahmud II announced the formation of a new army; the Janissaries mutinied. The court bombarded the barracks and suppressed the revolt, known in history as the "Auspicious Incident" (Vaka-i Hayriye). Death, execution, and exile tolls vary by source; common figures include about four thousand dead in the barracks fire and over six thousand executed. The corps was disbanded and replaced by a modern army.
