While thus its domination over the people was secure and unvarying, its relations with the royal power varied with the temperament of the sovereign. At times it was the instrument of his will; at others it seemed as though it might almost supplant the monarchy; it was constantly seeking to extend its awful authority over the other departments of State, which struggled with varying success to resist its encroachments, while successive kings, autocratic in theory, sometimes posed as arbitrators, sometimes vainly endeavored to enforce their pacificatory commands, but more generally yielded to its domineering spirit.
When Ferdinand consented to the introduction of the Inquisition, it was no part of his policy to permit the foundation of an institution which should be independent of the royal authority. He who sought to forbid in Spain the residence of papal nuncios and legates was not likely to welcome the advent of a new swarm of papal delegates, whose power over life and property would carry unchecked to every corner of the land the influence of Rome. Accordingly, as we have seen, he conditioned the admission of the Inquisition on the concession of the power of appointment and dismissal and he flatly told Sixtus IV that he would permit none but appointees of his own to exercise the office of inquisitor. As the institution developed and became more complex he nominated to the pope the individual to whom the papal delegation as inquisitor-general should be given and he appointed the members of the Suprema, which became known as the _Consejo de su Magestad de la Santa General Inquisicion_. Although the papal commission granted to the inquisitor-general faculties of subdelegating his powers and appointing and dismissing his subordinates, thus rendering his action indispensable, Ferdinand was careful to assert his right to control all appointments and to assume that at least they were made with his assent and concurrence. In 1485 the sovereigns had no scruple in appointing at Guadalupe the inquisitors who made such havoc among the apostates.[728] August 8, 1500, he writes to the Bishop of Bonavalle that he had determined to commit to him the office of inquisitor in Sardinia, for which the commission and subdelegation will be despatched to him by the inquisitors-general; he can appoint an assessor and notary, but the other officials will be sent from Spain. A letter of the same date to the Lieutenant-general of Sardinia announces the appointment by the inquisitors-general "con nuestra voluntad y consentimiento," which was the ordinary formula employed, even in such petty cases as when he advised Pedro Badía, receiver of confiscations at Barcelona, March 13, 1501, that they had appointed Gregorio Zamarado as _portero_ or apparitor of that tribunal, in place of Guillen Donadou and that he is to receive the same wages.[729] Although the participation of the inquisitor-general was indispensable, Ferdinand customarily assumed his acquiescence as a matter of course; he would make the appointment and then ask affectionately for the subdelegation of power.[730] As regards subordinate positions, Torquemada recognized the royal participation when, in 1485, he instructed inquisitors that they could fill vacancies temporarily "until the king and I provide for them." As a rule, it may be said that Ferdinand rarely troubled himself about subordinates, but had no hesitation in assuming full power when he saw fit, as in writing to an inquisitor, March 21, 1499, "we order you to appoint, as by these presents we appoint, Juan de Montiende as fiscal in your tribunal."[731]
