Haseki was the favourite concubine of an Ottoman Emperor in the times of Ottoman Empire. The haseki had an important place in the palace, being the second most powerful woman of the harem after the valide sultan, the mother of the emperor. Hasekis usually had chambers close to the Emperor's chamber. Also, since the hasekis were the women that the Emperor mostly went to bed to, they were generally the mother of the heir apparent. Nonetheless, a haseki was rarely a wife and didn't have a solid position in the palace. She could lose her state all at once, like Mahidevran Sultan did when Hürrem Sultan got her place.
