I'm asking this because I don't know if the cultural, religious and political situation of the Ottoman Empire would allow them to have a stratocracy, since the leader of the state is the sultan and he got the legitimacy to rule given from Islam, while the stratocracy is a Greek (and so western) concept that doesn't seems to fit well on the narrative. Anyway:
Could a coup happen in the Ottoman Empire during a period of economical crisis, instability, civil war or during a losing war against a greater foe, with the Janissaries taking total control and reorganizing the ottoman state, replacing regional governors and beys with military leaders and gearing the ottoman state to serve the army?
