Works & Achievements
Architectural complex commissioned by Kösem Sultan comprising a mosque adorned with Iznik tiles, a madrasa, and a hammam. This project reflects her role as a religious patron and benefactress to the people of Istanbul.
Effective governance of the Ottoman Empire during Murad IV's minority, including the management of appointments to high offices and the maintenance of stability against rival Janissary factions.
Following the death of Murad IV, Kösem Sultan guided the accession to the throne of her son Ibrahim I and continued to exert a decisive influence on state affairs despite the growing difficulties of his reign.
Following the deposition of Ibrahim I, Kösem Sultan served for the third time as regent of the Empire for her seven-year-old grandson Mehmed IV, maintaining alliances with the Janissaries until her assassination.
Kösem Sultan established numerous charitable foundations that funded mosques, schools, public fountains, and food distributions throughout the Empire, securing lasting popularity and reinforcing her political legitimacy.
Anecdotes
Born around 1589 into a Greek family, probably on the island of Tinos in the Aegean Sea, the young Anastasia was captured and sold into slavery before entering the Ottoman imperial harem. Her beauty and intelligence immediately struck Sultan Ahmed I, who made her his favorite and gave her the nickname Kösem, meaning "leader of the flock" in Turkish. She bore him several children, including Murad and Ibrahim, who would one day reign over the Empire.
After the death of Ahmed I in 1617, Kösem skillfully navigated the Ottoman successions and supported the accession to the throne of her sons: Murad IV in 1623, then Ibrahim I in 1640. During each of these reigns, she served as regent and managed the affairs of the Empire, becoming one of the most powerful women in Ottoman history — at a time when women were expected to play no public role whatsoever.
Kösem Sultan was renowned for her generosity toward the poor. She funded the construction of mosques, fountains, and *imarets* (public kitchens) throughout the Empire. According to several Ottoman chronicles, she personally paid for the release of prisoners unable to repay their debts and distributed considerable alms to the poor of Istanbul every year.
Her downfall was as dramatic as her rise to power. After the deposition of her son Ibrahim I in 1648, she became regent for her seven-year-old grandson Mehmed IV. Her rival, the young sultan's mother Turhan Hatice Sultan, gradually gained the upper hand. On the night of September 2, 1651, agents of Turhan Hatice stormed her apartments in Topkapi Palace and strangled her, bringing thirty years of political dominance to an end.
Kösem Sultan maintained a secret correspondence with Venetian ambassadors in Istanbul and negotiated prisoner exchanges with foreign powers. Reports from the Venetian *bailos* describe her as a woman of remarkable intelligence who had mastered the inner workings of Ottoman power and did not hesitate to deal as an equal with European diplomats — a practice highly unusual for a harem woman.
Primary Sources
The Sultan's Mother governs the kingdom's affairs with a skill and authority that few princes have managed to exercise; she commands the Janissaries, guides appointments, and conducts negotiations without the sultan taking any real part.
Kösem Sultan had mosques, imarets, and fountains built in many districts of Istanbul; each year, she distributed considerable sums to the poor and ransomed indebted prisoners who could not free themselves by their own means.
In that year, the Valide Sultan exercised the regency in the name of the young sultan Mehmed IV; she summoned the Divan, received ambassadors, and signed imperial firmans, supported by the Janissary commanders whom she had won over through her generosity.
We order that the Janissaries receive their pay without delay and that provincial revenues be remitted to the imperial treasury without embezzlement or delay; any violation of this order will be punished in accordance with the law.

Daily Life
Morning
Kösem Sultan rose early in her apartments in the Topkapi harem, surrounded by her ladies-in-waiting. After the morning prayer (fajr), she received reports from her agents on the political situation, conveyed through the Black eunuchs who served as liaisons between the harem and the rest of the palace. These early hours were devoted to gathering intelligence and making decisions.
Afternoon
Afternoons were given over to political affairs. Although women could not attend the Divan directly, Kösem Sultan delivered her instructions to the Grand Vizier through trusted eunuchs. She also granted audiences to the wives of dignitaries and oversaw the administration of her many charitable foundations across the Empire.
Evening
Evenings in the harem unfolded to a backdrop of music, storytelling, and conversation. Kösem Sultan supervised the education of the imperial family's princes and princesses and continued to receive news from outside through her network of informants. The evening prayer (isha) and the recitation of the Quran brought the day to a close.
Food
The Valide Sultan's table was magnificent: roasted lamb and poultry seasoned with spices, rice pilaf, stuffed vegetables (dolmas), pastries made with honey and pistachios (baklava, lokum), fresh and dried fruits, and drinks flavored with rose or tamarind. Meals were served on Chinese porcelain or precious metalware, a reflection of her imperial rank.
Clothing
Kösem Sultan wore richly embroidered caftans of silk and velvet threaded with gold and silver. Her head was covered with a turban adorned with diamond and ruby brooches. Her hair was braided and decorated with jewels, and she wore golden leather babouches. Every detail of her dress asserted her rank as the foremost woman in the Empire.
Housing
The Valide Sultan's apartments at Topkapi ranked among the most magnificent in the palace: vast halls lined with Iznik tiles in blue-and-white floral patterns, carved and painted wooden ceilings, softly murmuring indoor fountains, and divans piled with embroidered cushions. Private baths (hammam) and interior gardens completed a space that was as much a seat of power as a place of daily life.
