 After Pope Martin V had instituted a large number of offices in the "Cancellaria", Pope Sixtus V placed many of them in the class of ""vacabili"", i. e. venal offices (a practice also of secular courts, e. g. those of France, even under the absolutist King Louis XIV).The reclassification of many of the offices of the "Cancellaria" as "vacabili" was motivated by the need of the Pope for money.The Pope was often compelled to defend the Church by waging war, equipping martial expeditions, or at least financially assisting the princes who waged such wars at his exhortation, but the Papal treasury was often insufficient to defray even the expenses of the Papal States.
