During the early modern age the appointment of Maltese bishops involved conflicts in the management of ecclesiastical patronage, jurisdictional issues and international diplomacy. The procedure for appointment, established by Charles v in 1530 when he granted Malta to the Order of St John, was the result of a compromise: safeguarding rights of royal patronage without undermining the independence of an international military order. It is important, however, to underline the reforming activity conducted by bishops appointed in such political ways, especially through the application of some institutions provided by the Council of Trent, such as diocesan synods.
