 In 1484, Pope Innocent VIII attempted to allow appeals to Rome against the Inquisition, which would weaken the function of the institution as protection against the pope, but Ferdinand in December 1484 and again in 1509 decreed death and confiscation for anyone trying to make use of such procedures without royal permission..
With this, the Inquisition became the only institution that held authority across all the realms of the Spanish monarchy and, in all of them, a useful mechanism at the service of the crown.However, the cities of Aragón continued resisting, and even saw revolt, as in Teruel from 1484 to 1485.However, the murder of "Inquisidor" Pedro Arbués in Zaragoza on 15 September 1485, caused public opinion to turn against the "conversos" and in favour of the Inquisition.
