Cem Sultan

Cem Sultan was the third son of Sultan Mehmed II and younger half-brother of Sultan Bayezid II, and thus a half-uncle of Sultan Selim I of Ottoman Empire. After being defeated by Bayezid, Cem went in exile in Egypt and Europe, under the protection of the Mamluks, the Knights Hospitaller of St. John on the island of Rhodes, and ultimately the Pope. He was a claimant to the Ottoman throne in the 15th century, but he never succeeded in overthrowing his brother. He was also a patron of arts and culture, and a poet himself. He died in Capua, in the Kingdom of Naples, allegedly by poison. He was buried in Bursa, in the Muradiye Complex, where his father and other Ottoman sultans were also buried.
