Prince Cem (Jem Sultan)

الأمير جم سلطان

Prince Cem, son of Mehmed II: proclaimed sultan at Bursa on his father's death, he offered his brother Bayezid II first peace, then a partition — Europe to Bayezid, Asia to himself — which Bayezid refused as dissolving what their forefathers had united; defeated at Bursa, Cem fled to the Mamluk Qaytbay, who honoured him and equipped his hajj 1. Returning, he answered Bayezid's letter ('why chase worldly things, when kingship was my lot by God's command?') with 'Is it just that you lie on a bed of ease while I lay my head on thorns?' — raised his Anatolian followers, was defeated twice, and took refuge with the Knights of St John at Rhodes, who broke their compact under Bayezid's pressure and made him their prisoner, then sold the hostage to Pope Innocent VIII; on Innocent's death he passed to Alexander VI until he was killed — the chronicles, as al-Salabi relays, accusing Bayezid II 2.

Summary

Prince Cem, the younger surviving son of Mehmed II, rose against his brother Bayezid II after their father's death and ended his days a hostage in crusader hands 3.

The contested throne

At Bursa when news of his father's death reached him, the city's people acknowledged him sultan. He offered his brother peace, then a partition — Europe to Bayezid, Asia to himself. Bayezid refused to divide what their forefathers had laboured to unite and marched on Bursa; Cem fled to the Mamluk sultan Qaytbay in Egypt, who honoured him and equipped him for the hajj 1.

The letter and its answer

On returning from the hajj, Cem received Bayezid's letter: "Since you have performed your religious duty of the hajj, why chase worldly things, when kingship was my lot by God's command?" Cem answered: "Is it just that you lie on a bed of ease surrounded by servants, while I lay my head on thorns?" He roused his Anatolian followers and was defeated by Bayezid twice 3.

Hostage of the West

Cem took refuge at Rhodes with the Knights of St John; his compact with their Grand Master was broken under Bayezid's pressure, and he became their prisoner — a precious hostage that bought privileges now from Bayezid, now from Cem's backers in Cairo — until they sold him to Pope Innocent VIII for a great price. On Innocent's death Cem passed to Alexander VI until he was killed; the chronicles, as al-Salabi relays them, accused Bayezid II 2.
