Cem Sultan
Cem Sultan (c. 1459–1495) was an Ottoman prince and short-lived pretender to the throne, the third son of Sultan Mehmed II and younger brother of Bayezid II, whose unsuccessful bid for power after his father's death led to defeat and 13 years of captivity across Europe under Christian rulers.[1][2]
Following Mehmed II's death on 3 May 1481, Cem, then governor of Karaman, advanced on Bursa, seized the treasury, minted coins in his name, and was proclaimed sultan, holding effective control for approximately 20 days before Bayezid's forces defeated him at Yenişehir on 20 June 1481.[1][2] Fleeing through the Taurus Mountains to Mamluk Egypt, he sought refuge but later sailed to Rhodes on 26 July 1482, placing himself under the protection of the Knights Hospitaller, who treated him as a valuable hostage rather than a guest.[3][2] Transferred successively to French custody in 1482 and then to Pope Innocent VIII in Rome by 1489, Cem became a political instrument for European powers plotting against the Ottomans, with Bayezid II paying annual ransoms of 45,000 ducats to secure his containment and even offering 200,000 gold coins for his elimination.[3][1] Despite proposals to use him in crusading ventures or to partition the empire, no such plans materialized, and he remained confined until his death on 25 February 1495 in Capua, Kingdom of Naples, at age 35, with suspicions of poisoning by Bayezid's agents persisting in historical accounts.[3][1] His body was repatriated to Bursa in 1499 for burial in the Muradiye Complex.[3] Cem also composed poetry under the pen name "Cem" and left a legacy as a tragic figure in Ottoman chronicles, symbolizing fraternal rivalry and the perils of dynastic succession.[4]
