To replace these funds and raise new ones, the Avignon popes resorted to a host of moneymaking schemes, some old, some new. There were fees for this privilege and taxes for that. For example, the popes introduced the rule that whenever a bishop was appointed, the first year’s income—called an annat—should go to the pope. To fill a vacancy, popes often transferred a bishop from another city and thus created more annates. Or perhaps the pope delayed the appointment and received all the income in the interim. This was called a reservation.
