Upon the sudden death of Meḥemmed II in May, 1481, his two surviving sons, each hastily summoned from his provincial governorate by his own partisans among the Ottoman statesmen, set out with all speed to Istanbul. The race was won by the elder, Bāyezīd; but the younger son Jem had so strong and numerous a following that it was not until July, 1482, that he was finally obliged to admit defeat and take refuge at Rhodes with the Knights of St. John. The Grand Master, Pierre d'Aubusson, with a lively appreciation of the value of his guest as a hostage to insure Christendom against aggression by the new sultan—it was only two years since the Knights had beaten off a determined Ottoman siege—lost no time in removing him to France, where he would be less exposed to the danger of assassination by one of Bayezld's agents. For six years, well-treated but strictly guarded, Jem was confined in various houses of the Order in Savoy and France, his last prison, from whence he was handed into the custody of the Pope at the end of 1488, being the castle of Bourganeuf, in the present department of La Creuse, some 40 km. west of the Grand Master's native Aubusson. Jem's subsequent detention in Rome was brought to an end when he fell as a prize of war to Charles VIII of France in 1495, only to die at Naples a few weeks later.
