Seeking a counterweight to Janissary influence, Osman II closed their coffee shops (the gathering points for conspiracies against the throne) and started planning to create a new and more loyal army consisting of Anatolian sekbans. The result was a palace uprising by the Janissaries, who promptly imprisoned the young sultan in Yedikule Fortress in Istanbul, where Osman II was strangled to death. After Osman's death, his ear was cut off and represented to Halime Sultan and Sultan Mustafa I to confirm his death and Mustafa would no longer need to fear his nephew. It was the first time in the Ottoman history that a Sultan was executed by the Janissaries.
