Handan Sultan
Handan Sultan (c. 1570 – 9 November 1605) was a Bosnian-origin concubine who rose to become the consort of Ottoman Sultan Mehmed III and the Valide Sultan (queen mother) to their son, Sultan Ahmed I, from his accession in December 1603 until her death.[1] Gifted as a slave girl to Prince Mehmed by Cerrah Mehmed Pasha around 1582, she entered his harem in Manisa and bore Ahmed I in 1590, positioning her as a key figure in the imperial lineage amid the Ottoman succession practices.[1] As Valide Sultan, Handan exercised significant influence during Ahmed I's minority, serving as de facto co-regent with the tutor Mustafa Efendi and orchestrating the expulsion of the powerful Safiye Sultan—Ahmed's grandmother—from the court on 9 January 1604 to consolidate her authority.[1] She cultivated a network of loyal officials, favoring those of Bosnian and Balkan extraction, and influenced critical appointments such as grand viziers and palace aides, thereby shaping early policies and stabilizing the throne during a period of internal factionalism.[1] Her regency, though brief, marked her as a precursor to more formalized queen-mother governance in Ottoman politics, demonstrating the valide's capacity for direct political intervention grounded in maternal authority and patronage networks.[1] Handan died at Topkapı Palace on 9 November 1605 and was buried in the Hagia Sophia mausoleum adjacent to Mehmed III's tomb.[1]
