Cem 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.
