メフメト4世
At the head of the Ottoman Empire stood the child sultan, Mehmed IV. With Mehmed's ascendancy, the position of valide sultan ("mother of the reigning sultan") should have gone to his mother Turhan Sultan. However, Turhan was overlooked due to her youth and inexperience. Instead Kösem was reinstated to this high position. Kösem was a valide (mother) under two sons, thus having the more experience of the two women. The feud intensified between Turhan Sultan, the mother of Sultan Mehmed IV, whose influence began to increase. This feud continued for 3 years, until Kösem sought to overthrow her grandson Mehmed IV, particularly because of his powerful mother, Turhan Sultan, and replace him with Şehzade Suleiman.
