Roxelana, wife of Suleiman the Magnificent (b. c. 1500)
Hurrem Sultan (Turkish pronunciation: [hyɾˈɾæm suɫˈtan], Ottoman Turkish: خُرّم سلطان, romanized: Ḫurrem Sulṭān, Modern Turkish: Hürrem Sultan; c. 1502 – 15 April 1558), also known as Roxelana (Ukrainian: Роксолана; lit. 'the Ruthenian one'), was the chief consort and wife of the Ottoman sultan Suleiman the Magnificent. She became one of the most powerful and influential women in Ottoman history as well as a prominent and controversial figure during the era known as the Sultanate of Women.

Born in Ruthenia (then an eastern region of the Kingdom of Poland, now Ukraine) to a Ruthenian Orthodox priest, Hurrem was captured by Crimean Tatars during a slave raid and eventually taken to Istanbul, the Ottoman capital. She entered the Imperial Harem, rose through the ranks and became the favourite of Sultan Suleiman. Breaking Ottoman tradition, he married Hurrem, making her his legal wife; sultans had previously married only foreign free noble ladies. She was the first imperial consort to receive the title Haseki Sultan. Hurrem remained in the sultan's court for the rest of her life, having six children with him, including the future sultan, Selim II. She was the grandmother of Murad III.

Hurrem eventually achieved power, influencing the politics of the Ottoman Empire. Through her husband, she played an active role in affairs of the state. She probably acted as the sultan's advisor, wrote diplomatic letters to King Sigismund II Augustus of Poland (r. 1548–1572) and patronized major public works (including the Haseki Sultan Complex and the Hurrem Sultan Bathhouse). She died in 1558, in Istanbul and was buried in a mausoleum within the Süleymaniye Mosque complex.
