Question: why sehzade mustafa was killed?
Answer: Murder of Şehzade Mustafa. Şehzade Mustafa, among the three princes, was the heir to both the throne because of his popularity by the people of Anatolia as well as with the Janissaries. Therefore, Hürrem Sultan was plotting the death of her stepson in order to provide the succession of her son Şehzade Selim.
