Mihrişah Sultan (mother of Selim III)

[11][12][13] 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.

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.

[clarification needed] Upon Abdul Hamid's death in 1789, Selim ascended the throne after which Mihrişah became the Valide Sultan.

[17] 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.

[17] 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.
