For centuries, the Church in Malta was subordinate to the Diocese of Palermo, except when it was under Charles of Anjou, who appointed bishops for Malta, as did – on rare occasions – the Spanish and later, the Knights. Since 1808 all bishops of Malta have been Maltese. As a result of the Norman and Spanish periods, and the rule of the Knights, Malta became the devout Catholic nation that it is today. It is worth noting that the Office of the Inquisitor of Malta had a very long tenure on the island following its establishment in 1530: the last Inquisitor departed from the Islands in 1798 after the Knights capitulated to the forces of Napoleon Bonaparte. During the period of the Republic of Venice, several Maltese families emigrated to Corfu. Their descendants account for about two-thirds of the community of some 4,000 Catholics that now live on that island.
