عثمان الثاني
Mustafa was never more than a tool of court cliques at the Topkapı Palace. In 1618, after a short rule, another palace faction deposed him in favour of his young nephew Osman II (1618–1622), and Mustafa was sent back to the Old Palace. The conflict between the Janissaries and Osman II presented him with a second chance. After a Janissary rebellion led to the deposition and assassination of Osman II in 1622, Mustafa was restored to the throne and held it for another year.
