She was de facto co-ruler as Valide Sultan from 22 November 1617 to 26 February 1618 and from 19 May 1622 to 10 September 1623, because her son was mentally instable.

The seer responded, but the message was intercepted by Abdürrezzak Agha, the chief black eunuch of the imperial harem, and who later gave it to Mehmed and Safiye, instead of her.

No one had expected that Mustafa, who suffered from severe emotional problems, would become sultan, and so she had not enjoyed a position of much status within the imperial harem.

One of the few political alliances the valide was able to forge with her son's sword-bearer, Mustafa Agha, a high ranking inner palace officer, who was brought out of the palace and awarded the prestigious and strategically vital post of governor of Egypt on condition that he would marry the Sultan's wet nurse.

From her location in the Old Palace, she was a key figure in the deposition and assassination of Osman II and showed that she was no stranger to the art of damat politic.

[15] The basic and exceptional weakness from which Osman II suffered was the conspicuous absence of a female power basis in the harem.

Seeking a counterweight to Janissary influence, Osman II closed their coffee shops and started planning to create a new and more loyal army consisting of Anatolian sekbans.

Later on 18 May 1622 Osman was again dethroned and the rebels, meanwhile, broke into the imperial palace and freed Mustafa from his confinement and acclaimed him as their master.

Some of the janissaries consulted with her about the appointments to be made and it was in fact her son-in-law, Kara Davud Pasha, who became the grand vizier.

Their uneasiness was well grounded, since some of the rebels wished to spare Osman, hoping no doubt to make no use of him for their own ends at some future date.

Kara Davud Pasha had recourse, therefore to the last extreme measure on 20 May 1622, Osman II was strangled in the prison of Yedikule in Istanbul.
