The Sultanate of Women was the nearly 130-year period during the 16th and 17th centuries when the women of the Imperial Harem of the Ottoman Empire exerted extraordinary political influence over state matters and over the (male) Ottoman sultan, starting from the reign of Suleiman the Magnificent. Many of the Sultans during this time were minors and it was their mothers, the Valide Sultans, or their wives, the Haseki Sultans, who effectively ruled the Empire. Most of these women were of slave origin, which was often the case in general for consorts of Ottoman sultans.
