Guarding Cem
D'Aubusson accepted an annuity of 45,000 ducats from Bayezid II, in return for which he undertook to guard Cem in such a way as to prevent him from appealing to the Christian powers to aid him against his brother.
D'Aubusson's reward was a cardinal's hat (1489) and the power to confer all benefices connected with the Order without the sanction of the papacy. In addition, the Order of St. John received the assets of the Order of the Holy Sepulchre, which was merged into the Order of St. John, and a number of Italian commandries of the Knights of St. Lazarus.
