passage: Ibrahim of the Ottoman Empire
Ibrahim was born on 5 November 1615, the son of Sultan Ahmed I and his favorite concubine who later became his legal wife, Kösem Sultan. When Ibrahim was 2, his father suddenly died, and Ibrahim's uncle Mustafa I became the new sultan. By that time, Kosem Sultan and her children, including young Ibrahim had been sent to the Old Palace. After the succession of his brother Murad IV, Ibrahim was confined in the Kafes, which affected his health. Ibrahim's other brothers Şehzade Bayezid, Şehzade Suleiman and Şehzade Kasım had been executed by the order of Sultan Murad IV, and because of that Ibrahim feared that he was next in the line. However, after his brother's death, Ibrahim became the Sultan of the Ottoman Empire.
