This is a list of the biological mothers of Ottoman sultans.
There were thirty-six sultans of the Ottoman Empire in twenty-one generations (during early days the title Bey or Ghazi was used instead of Sultan).
Throughout the six-century history the sultans were the members of the same house, namely the House of Osman (Turkish: Osmanlı Hanedanı).
The mothers who died before their sons' accession to throne, never assumed the title of Valide Sultan like Hürrem, Muazzez, Mihrişah,[1][2] and Şermi.
[3] On the other hand, step mothers who were not the biological mothers but raised the princes whose mothers had died assumed the title of Valide Sultan like Perestu.
