Cem's Offer

When Bayezid II became sultan of the Ottoman Empire in 1481, he had a rival: his half-brother Cem (22 December 1459 - 25 February 1495). Cem was the third son of Sultan Mehmed II, who conquered Constantinople and then died without choosing a successor. Cem and Bayezid each ruled provinces, and each believed himself ready and able to become the next sultan.

The Grand Vizier tried to arrange things so that Cem could arrive at his father's funeral before Bayezid and claim the throne at Constantinople. Bayezid, however, already had several important pashas and the Janissaries in his corner. The Janissaries entered the palace, lynched the Grand Vizier, and Bayezid was urged to reach Constantinople as soon as possible.

Cem fled west with an army loyal to him, declaring himself Sultan of Anatolia and proposing that the empire be split; Bayezid could have the western half. Bayezid disagreed, and sent his army after Cem. A battle ensued in which Cem's side lost, and Cem fled to Cairo.

While in Cairo, he received a letter from Bayezid, offering him 1,000,000 akçes (a silver coin that was the standard unit of Ottoman currency) to give up his claim. Instead, Cem tried to conquer the city of Konya in Turkey, but failed. He then fled to Rhodes and asked for the protection of the Knights of St. John, also known as the Hospitallers.

Cem's offer to them was to create a perpetual peace between the Ottoman Empire and Christianity if they would help him overthrow Bayezid. The grand master of the Knights, Pierre d'Aubusson, knew a war with Bayezid could be disastrous, so when he had a message from Bayezid making a counter-offer, he accepted it. 

The counter-offer was simple: Bayezid would make an annual payment in gold to the Knights if they would take and keep Cem captive. He was sent to France under the saintly King Louis IX (who did not like having a Muslim in his lands), and kept for a year in the Duchy of Savoy, and then five years at Pierre d'Aubusson's birthplace, Limousin. (The illustration shows the tower built specially to hold him in comfort.) After Charles VIII came to the throne, Bayezid asks that Cem be transferred back to Rhodes. His value as a hostage meant several leaders wanted to "host" him, but ultimately Pope Innocent VIII won out.

In March 1489, Cem was transported to Rome and the custody of Pope Innocent VIII. Whenever word came that Bayezid was about to launch an offensive against Christians, Innocent would send a message to Bayezid, threatening to release Cem from captivity and giving the Ottomans an alternative sultan around whom they could form an insurrection.

Bayezid ultimately sent Innocent 120,000 crowns, a relic of the Holy Lance (stored in Constantinople), and an annual fee of 45,000 ducats for Cem's "room and board." Bayezid sent spies to ensure that Cem was kept under lock and key, and even tried to assassinate him.

...and then Innocent wanted a Crusade against the Ottomans. I'll continue that story—and Cem's end—tomorrow.

Guillaume Caoursin

Yesterday's post on Mesih Pasha mentions the Siege of Rhodes in 1480, when a small garrison of Knights Hospitallers at Rhodes withstood an attack by the Ottomans. The garrison was led by Grand Master Pierre d'Aubusson. The vice-chancellor of the order was Guillaume Caoursin, who wrote (among other things) an account of the event.

Caoursin was born in 1430 in Douai in northern France, and joined the Order of Saint John (also know as the Hospitallers) as a young man. By 1462 he was vice-chancellor of the Order in Rhodes, and in 1462 he accompanied the Grand Master Piero Raimondo Zacosta to Rome for the holding of a general chapter under the guidance of Pope Paul II.

While in Rome, Zacosta died (he was in his 60s), and Giovanni Battista Orsini succeeded him. Caoursin went back to Rhodes with the new Grand Master, but was sent back to Rome in 1470 to request help from the pope for dealing with the Turks. Orsini died in 1476, and Caoursin now worked under Grand Master Pierre d'Aubusson.

In 1480, Mesih Pasha led an Ottoman force of 160 ships and 70,000 men against Rhodes. While the Turks bombarded the walls, the citizens dug a new moat and new fortification within the city walls near the Jewish quarter in case the bombardment breached the walls.

On 27 July the Janissaries managed to enter the city. d'Aubusson led the fighting, though wounded in five places. A three-hour battle forced the Turks back, and the Knights pursued all the way back to the Ottoman tents, taking booty and the holy standard of Islam. Caoursin reported that between three and four thousand Turks were slain that day. The Ottomans gave up on 17 August.

Caoursin married shortly after 1480. He was rewarded by d'Aubusson with 1000 gold florins for his services to the Order. His "next act" came in 1484, when he became ambassador to Pope Innocent VIII. Innocent was so impressed by Caoursin that he made him his apostolic secretary. Caoursin remained there, writing about his Order and about Rhodes.

Innocent VIII might also have kept Caoursin close because of his knowledge of the Ottomans and the Siege of Rhodes, of which I will have more to say tomorrow.
