Cæsar Borgia, his younger son, had been educated for the church; and, despite his illegitimate birth, was raised to the rank of cardinal. But Caesar disliked the sacerdotal profession, and was jealous of his elder brother, the duke of Candia, whom his father was desirous of raising to the highest temporal rank, both because of his success in arms, and also on account of the preference shown him by their sister Lucretia. Incited by these criminal passions, he one night caused the duke to be waylaid, murdered, and thrown into the Tiber. The pope was at first overwhelmed with grief on his son's death, and made great show of repentance and reformation; but soon after he cast aside all thoughts of this kind, and returned with renewed eagerness to his former pursuits and projects. Cæsar gained the point at which he aimed. He was permitted to abdicate the cardinal's hat; and, in reward for the dispensation which the pope granted Louis XII. to divorce his first wife, and to marry Anne of Britany, he obtained the duchy of Valence in France, and henceforth was commonly called by the name of the duca Valentino, or Valentian duke. It was the chief ambition of this new temporal noble to form a principality in Italy. The territories of the marquisate of Savoy, of the duchy of Milan, and of the Venetian republic, embraced the greater portion of the peninsula north of the Apennines. To the south, the kingdom of Naples, Rome, and the republic of Florence, were the principal states; but other territories remained, a sovereignty over which was claimed by the popes, but which obeyed a variety of petty lords, whose families had for centuries enjoyed the rule. The various cities of Romagna to the east, Bologna to the north, Piombino to the west, and Perugia to the south, formed the chief: of these Cæsar Borgia resolved to possess himself, extending a prophetic eye to the future conquest of Tuscany. Already he had acquired dominion over Romagna: he dispossessed the duke of Urbino and the prince of Piombino of their states, and now he turned his eyes towards Bologna. Giovanni Bentivoglio had long been lord of this wealthy city; good fortune, rather than talents or a spirit of enterprise, had raised him, and he spared no blood in confirming his power. Cæsar Borgia was supported in his encroachments by an alliance with Louis XII. In vain was it represented to this monarch[114], "that it ill became the splendour of the French crown, and the title of most Christian king, to show favour to an infamous tyrant, the destroyer of many states; a man who thirsted for human blood, and was an example to the whole world of perfidy and inhumanity; who, like a public robber, had broken faith with and murdered so many princes and nobles; one stained with the blood of his nearest kindred, and whose crimes of poisoning and stabbing were unequalled in a Christian country." Louis favoured him, not so much from his own inclination, as at the instigation of the cardinal d'Amboise,
