Some women of Ottoman harem, especially wives, mothers and sisters of sultans, played very important political roles in Ottoman history, and in times it was said that the empire was ruled from harem. This period of Ottoman history is known as the Sultanate of Women. Hürrem Sultan (wife of Suleiman the Magnificent, mother of Selim II), was one of the most powerful women in Ottoman history, and wielded vast political power. The title of Haseki Sultan, was created for her and was used by her successors.
