The so-called “Apostolic Legation” (Apostolica Legazia) was a privilege claimed by the Kings of Sicily that consisted of the right to nominate bishops on the island. The theory behind it was that the ruler of Sicily was concurrently a papal legate. Pope Urban II supposedly granted the right to Roger of Hauteville in the 1098 bull Quia propter prudentium tuam. It was later the subject of protracted negotiations between the Kings of Sicily and the Roman Curia, and much scholarship has been devoted to the question of whether it was ever really granted. It is nevertheless undeniable that the rulers of Sicily exercised the power of nomination over bishops on the island from the Norman conquest onward.
