Don Juan fell back to Guadalajara, where terms were agreed upon, the principal articles being that Nithard should immediately resign all his offices and never return to Spain and that Diego de Valladares, Don Juan's special enemy, should have nothing to do in any matter affecting him. Nithard accordingly went to Rome, but he had no commission to show and no instructions. He reported this to the Council of State, which told him to urge the definition by the Holy See of the Immaculate Conception. The queen endeavored by a subterfuge to obtain for him a cardinal's hat, which had been promised to Spain, but failed. He still hoped for a return to his honors, stimulated by the correspondence of his confidential agent, the Jesuit Salinas, but a letter warning him not to resign the inquisitor-generalship, for things were tending towards his return, with a lodging in the queen's palace, chanced to fall into the hands of the nuncio, who placed it where it would do the most good. The result was a peremptory order for him to resign in favor of Valladares, who had been nominated as his successor. When this was handed to him by San Roman, the Spanish ambassador, he is said to have fainted and not to have recovered his senses for an hour. The coveted cardinal's hat was bestowed on Portocarrero, Dean of Toledo, and when the news of this reached the queen it threw her into a tertian fever. The Jesuit General Oliva, seeing Nithard thus stripped of his offices and offended at his arrogance, ordered him to leave Rome and he retired to a convent, but he was amply provided with funds and, for some years at least, he was carried on the books of the Suprema and received his salary regularly. Moreover, in 1672, the queen procured from Clement X what Clement IX had persistently refused and Nithard was created Archbishop of Edessa and cardinal.[780]
Valladares had received his appointment September 15, 1669. It was not until 1677 that he resigned his see of Plasencia and he held the inquisitor-generalship until his death, January 29, 1695. He was succeeded by Juan Thomás de Rocaberti, Archbishop of Valencia, for whom Innocent XII, at the request of Carlos II, granted a dispensation from residence, conditioned on his making proper provision for the spiritual and temporal care of his see.[781] He died June 13, 1699, and his successor, Alfonso Fernández de Aguilar, Cardinal of Córdova, followed him September 19th, the very day that his commission arrived, after a brief illness and not without grave suspicions of poison.[782] The choice then fell on Balthasar de Mendoza y Sandoval, Bishop of Segovia, who became involved, as we shall see, in a deadly quarrel with his colleagues of the Suprema over the case of Fray Froilan Díaz. In the confusion of the concluding months of the disastrous reign of Carlos II, who died November 1, 1700, Mendoza made the mistake of embracing the Austrian side; his arbitrary action, in the case of Froilan Díaz, served as a sufficient excuse for his removal and Philip V, apparently in 1703, ordered him to return to his see. He is generally said to have resigned in 1705 but, in the papal commission, March 24, 1705, for his successor Vidal Marin, Clement XI states that he has seen fit to relieve Mendoza of the office because his presence is necessary at Segovia.[783] Vidal Marin served till his death in 1709 and so did his successor Riva-Herrera, Archbishop of Saragossa, who, however, enjoyed his dignity for little more than a year.
