His successor in the see of Toledo has a special interest for us in view of his labors to purify the faith which culminated in establishing the Inquisition. Pero González de Mendoza was one of the notable men of the day, whose influence with Ferdinand and Isabella won for him the name of "the third king." While yet a child he held the curacy of Hita; at twelve he had the archdeaconry of Guadalajara, one of the richest benefices in Spain, which he retained during the successive bishoprics of Calahorra and Sigüenza and the archbishopric of Seville; the see of Sigüenza he kept during the whole tenure successively of the archiepiscopates of Seville and Toledo, in addition to which he was a cardinal and titular Patriarch of Alexandria. With his kindred of the powerful house of Mendoza he adhered to Henry IV, until they effected the sale of the hapless Beltraneja, who was in their hands, to her father, Henry, for certain estates and the title of Duke del Infantado for Diego Hurtado, the head of the family, after which Pero González and his kinsmen promptly transferred their allegiance to Isabella. His admiring biographer assures us that he was more ready with his hands than with his tongue, that he was a gallant knight and that there was never a war in Spain during his time in which he did not personally take part or at least have his troops engaged. Though he had no leisure to attend to his spiritual duties, he found time to yield to the temptations of the flesh. When, in 1484, he led the army of invasion into Granada he took with him his bastard, Rodrigo de Mendoza, a youth of twenty, who was already Señor del Castillo del Cid, and who, in 1492, was created Marquis of Cenete on the occasion of his marriage, amid great rejoicings, in the presence of Ferdinand and Isabella, to Leonor de la Cerda, daughter and heiress of the Duke of Medina Celi and niece of Ferdinand himself. This was not the only evidence of his frailty of which he took no shame, for he had another son named Juan, by a lady of Valladolid, who was married to Doña Ana de Aragon, another niece of Ferdinand.[26] [Sidenote: _CONDITION OF THE CHURCH_]
