All the girls of the harem, who were lucky enough to receive the attention of the sovereign, wanted to give birth to as many boys as possible. The more sons - the higher your position in the harem and the more power.
Despite the fact that the concubines knew about the harsh laws of the Ottoman dynasty, their main goal is to give birth to a son and more than one. Although I am sometimes surprised by such a desire - to give birth to sons, knowing that only one will remain alive, and not the fact that it is yours.
Indeed, according to the law of the Ottomans, the Shahzadeh who ascended the throne must kill all his brothers.
Sultan Suleiman had two concubines who were able to give him sons, and each of them built intrigues, trying to "put" their own offspring on the throne.
Of course, when it comes to your own child, there is nothing to disdain, but watching the series, I feel very sorry for both Shahzadeh - Mustafa and Mehmet.
Both were kind, fair and worthy heirs, but their mothers went "over their heads" clearing the way for their son. As a result of such enmity, both ladies lost their firstborn.
Makhidevran, having left with Shahzade Mustafa for Manisa, did not intrigue Mehmet and Khyurrem for a long time. Mahidevran was sure that it was her shahzade who would ascend the throne after the sovereign.
But when the sultan sent Mustafa to Alaska and gave Mehmet Manisa's sanjak, Mahidevran was quite worried. She understood that now Mehmet is the main heir to the throne and decided to remove him from the path.
Mahidevran sent her loyal servant Ilyas - aga to Mehmet so that he could gain confidence in him.
And then she ordered to remove Mehmet, but so that not a shadow of doubt fell on her.
Ilyas - yeah, he tried more than once to carry out the order of his mistress, but every time something went wrong. At that time, a terrible disease fell on Manisa - smallpox and the servant took advantage of it. He "accidentally" wounded Shahzadeh, and then put a handkerchief to his wound after a patient with smallpox.
Mehmet could not cope with this misfortune and departed to another world.
Of course, the shed blood of Mehmet is on the hands of Mahidevran, but it was not possible to prove her involvement in this sad event.
