Which Ottoman sultan was killed by his own Janissaries in 1622?

Osman II was the Ottoman sultan killed by his own Janissaries in 1622.

Born in 1604, Osman became sultan in 1618 while still a teenager. He sought to strengthen central authority and reduce the political influence of the Janissary corps, whose military power had increasingly shaped palace politics. His plans, along with dissatisfaction over military failures and his attempt to recruit a new army, provoked fierce opposition.

In May 1622, rebellious Janissaries and allied forces deposed Osman and imprisoned him. He was killed in Constantinople shortly afterward, becoming the first Ottoman sultan assassinated by his own subjects. His death demonstrated how influential the Janissaries had become in determining succession.

A common mix-up is Mustafa I, who was placed on the throne after Osman’s deposition and restored briefly afterward. Murad IV later reasserted control over the corps, while Ibrahim I ruled decades later. Neither was killed in the 1622 Janissary revolt.
