Overview
Hatice Mahfiruz Hatun or Mahfiruze Hatun (Ottoman Turkish: ماه فروز خاتون, "Glorious moon" or "Daytime moon" or "Turquoise Moon"; 1590 - before 1618) was a consort of Ottoman Sultan Ahmed I (r. 1603–17) and the mother of Osman II (r. 1618–22).
Biography
Due to the preeminence of Kösem Sultan during Ahmed's reign, there aren't many records about her life. She was a concubine, who may have been of Circassian origin. She was Ahmed's first concubine, and on 3 November 1604 she gave birth to Ahmed's firstborn, the future Osman II, making Ahmed I the youngest Ottoman sultan to have fathered a child.
Despite this, she was not given the title of Haseki Sultan, which instead was given to Kösem, the most beloved consort of Ahmed and mother of at least four other sons and three daughters, which deprived Mahfiruz of all power. However, she received the title of Başkadin (mother of the Sultan's firstborn-male).
She disappears from the harem records shortly after Osman was born. While it was initially believed that she was disgraced and exiled, it is now believed that she died between 1608 and 1613, maybe in childbirth, and therefore was never her son's Valide Sultan, who ascended the throne in 1618.
