Many years later, towards the end of Suleiman's long reign, the rivalry between his sons became evident. Mustafa was later accused of causing unrest. During the campaign against Safavid Persia in 1553, because of fear of rebellion, Suleiman ordered the execution of Mustafa. According to a source he was executed that very year on charges of planning to dethrone his father; his guilt for the treason of which he was accused remains neither proven nor disproven. After the death of Mustafa, Mahidevran lost her status in the palace as the mother of the heir apparent and moved to Bursa. She did not spend her last years in poverty, as her stepson, Selim II, the new sultan after 1566, put her on a lavish salary. Her rehabilitation had been possible after the death of Hurrem in 1558. Cihangir, Hurrem's youngest child, allegedly died of grief a few months after the news of his half-brother's murder.
