Mihrişah Sultan (Turkish, Ottoman (1500-1928);: مهرشاہ سلطان; "sun/light of the Şah"; 1745 – 16 October 1805), was a consort of Sultan Mustafa III, and the mother of Selim III of the Ottoman Empire, and his Valide sultan for 16 years from 1789 until 1805.
Of ethnic Georgian origin, Mihrişah was born in 1745 in Georgia, but there were also rumors that she was in part Genoese.[2] [3] Her original name was Agnes.[4] [5] She was considered beautiful,[6] and was called "the Georgian Beauty" (Turkish: Gürcü güzeli).[7] [8]
Mihrişah entered in Mustafa III's harem via the Black Sea slave trade circa 1757 and became one of his consorts and then the BaşKadin (first consort).[9] On 17 March 1759, she gave birth to her first child, a daughter, Hibetullah Sultan.[10] [11] [12] For the past thirty years no child had been born in the imperial family, hence, Hibetullah's birth was celebrated in the whole of Istanbul.
On 24 December 1761, she gave birth to her second child, a son, Şehzade Selim (future Selim III). His birth was accompanied by celebrations that lasted a week.[13] On 9 January 1770, she gave birth to her third child, a daughter, Fatma Sultan, who died at the age of two on 26 May 1772.[11] [14] Among her servants was Dilhayat Kalfa, hostess of Ahmed III's harem and tutoress of Selim III, known to be one of the greatest Turkish composeress of the early modern period.
She was widowed in 1774, after which she settled in the Old Palace. An archival document from the Topkapi Palace shows that Mustafa III borrowed money from her and that, due to his death, the debt was not repaid.
Mihrişah and her son Selim were both members of the Mevlevi Order, which practiced Sufi whirling.
During the reign of Sultan Abdul Hamid I, which lasted for fifteen years, Şehzade Selim remained closed in the Topkapı Palace, and the Mihrişah was sent to live in the Old Palace. Upon Abdul Hamid's death in 1789, Selim ascended the throne after which Mihrişah became the Valide Sultan. She occasionally approached her son to beg a favour or an act of mercy. When he launched his Nizam-I Cedid (New Order), both Mihrişah and her Kethüda, by then Yusuf Agha, were his strong supporters. To encourage the reforms so dear to her son's heart, Mihrişah built a mosque for the Humbaracıhane (barracks of the bombardiers) at Hasköy on the Asiatic shore, and founded a school of medicine at Üsküdar.
Yusuf Agha was her second kethüda, who had replaced her first kethüda Mahmud Agha, when he died during tenure of his office. He was capable, and an intimate of Selim. He was persuaded and finally killed by the machinations of Kabakçı Mustafa in the uprising against Selim in 1808, after which his tax farm was given to Sultan Mustafa IV's mother, Sineperver Sultan.
Mihrişah was very active in the 1790s as a patron of architecure, especially schools and mosques.
The Humbarahane Barracks, which Mihrişah founded in 1792 is considered the first modern example of large-scale military buildings.[15]
The Mihrişah Sultan Complex, which Mihrisah founded in 1792 and which was completed in 1796, is in the neighbourhood of Eyüp in Istanbul. It includes her mausoleum and an imaret (soup kitchen), today the last still-functioning Ottoman imaret.[16]
In 1793, Mihrişah founded Halıcıoğlu Mosque.
Mihrişah was responsible for the building of the Vâlide Dam on the eastern branch of Arabacı Mandrai in Istanbul, to provide additional water supply to the Büyük Bent.
Mihrişah also built a number of fountains:
Fountains built by Mihrişah met the water needs of people in the Beyoğlu, Galata and Boğaziçi neighbourhoods.
Mihrişah Sultan died on 16 October 1805 of unknown causes. She was buried in her charitable complex located at Eyüp, Istanbul.
Together with Mustafa III, Mihrişah had a son and two daughters:
