Kadın (title) in the context of Haseki sultan

Haseki Sultan (Ottoman Turkish: خاصکى سلطان, romanized: Hāṣekī Sulṭān, Turkish pronunciation: [haseˈci suɫˈtaːn]) was a title used for the favorite of an Ottoman sultan. It was created for Hürrem Sultan, the legal wife of Suleiman the Magnificent. The title lost its exclusivity under Ibrahim, who bestowed it upon eight women simultaneously, but continued to be used until the 17th century, when kadın became the highest-ranking title for imperial concubines.
