Kösem Sultan, born in 1589, was a formidable figure in the Ottoman Empire, known for her roles as a regent, slave, and writer. As the legal wife of Sultan Ahmed I, she was the mother of Murad IV and Ibrahim, and the grandmother of Mehmed IV. Her political acumen allowed her to effectively govern during the minority of her sons and grandson, making her one of the most influential women in Ottoman history.
Her regency spanned several tumultuous periods: from 1623 to 1632 during Murad IV's minority, from 1640 to 1648 amid Ibrahim's unstable rule, and again from 1648 until her assassination in 1651 during Mehmed IV's minority. Kösem's influence was bolstered by her extensive family ties, as her daughters' marriages to prominent statesmen provided her with crucial allies within the government.
Kösem was not only a powerful political figure but also a beloved personality among the common citizens and the ruling elite. Her early regency was marked by unrest, yet she managed to maintain the integrity of state institutions. In 1645, she urged Sultan Ibrahim to undertake a naval assault on Crete, which ultimately proved unsuccessful, leading to further challenges such as the Venetian blockade of the Dardanelles and the naval Battle of Focchies in 1649.
While some historians attribute the decline of the Ottoman Empire to Kösem's policies, others view her actions as desperate attempts to prevent a succession crisis and safeguard the dynasty. Posthumously, she was honored with titles such as Vālide-i Muazzama, Vālide-i Maḳtūle, Umm al Mu'minīn, and Vālide-i Şehīde, reflecting her complex legacy as a powerful matriarch in a male-dominated society.
