Nevertheless, a few general remarks on the Papacy can hardly be dispensed with. New and strange perils and trials came upon it in the course of the fifteenth century, as the political spirit of the nation began to lay hold upon it on various sides, and to draw it within the sphere of its action. The least of these dangers came from the populace or from abroad; the most serious had their ground in the characters of the Popes themselves.
Let us, for this moment, leave out of consideration the countries beyond the Alps. At the time when the Papacy was exposed to mortal danger in Italy, it neither received nor could receive the slightest assistance either from France, then under Louis XI., or from England, distracted by the wars of the Roses, or from the then disorganized Spanish monarchy, or from Germany, but lately betrayed at the Council of Basel. In Italy itself there were a certain number of instructed and even uninstructed people, whose national vanity was flattered by the Italian character of the Papacy; the personal interests of very many depended on its having and retaining this character; and vast masses of the people still believed in the virtue of the Papal blessing and consecration;222 among them notorious transgressors like that Vitellozzo Vitelli, who still prayed to be absolved by Alexander VI., when the Pope’s son had him slaughtered.223 But all these grounds of sympathy put together would not have sufficed to save the Papacy from its enemies, had the latter been really in earnest, and had they known how to take advantage of the envy and hatred with which the institution was regarded.
And at the very time when the prospect of help from without was so small, the most dangerous symptoms appeared within the Papacy itself. Living, as it now did, and acting in the spirit of the secular Italian principalities, it was compelled to go through the same dark experiences as they; but its own exceptional nature gave a peculiar colour to the shadows.
As far as the city of Rome itself is concerned, small account was taken of its internal agitations, so many were the Popes who had returned after being expelled by popular tumult, and so greatly did the presence of the Curia minister to the interests of the Roman people. But Rome not only displayed at times a specific anti-papal radicalism,224 but in the most serious plots which were then contrived, gave proof of the working of unseen hands from without. It was so in the case of the conspiracy of Stefano Porcaro against Nicholas V. (1453), the very Pope who had done most for the prosperity of the city, but who, by enriching the cardinals, and transforming Rome into a papal fortress, had aroused the discontent of the people.225 Porcaro aimed at the complete overthrow of the papal authority, and had distinguished accomplices, who, though their names are not handed down to us,226 are certainly to be looked for among the Italian governments of the time. Under the pontificate of the same man, Lorenzo Valla concluded his famous declamation against the gift of Constantine, with the wish for the speedy secularisation of the States of the Church.227
The Catilinarian gang, with which Pius II. had to contend228 (1460), avowed with equal frankness their resolution to overthrow the government of the priests, and its leader, Tiburzio, threw the blame on the soothsayers, who had fixed the accomplishment of his wishes for this very year. Several of the chief men of Rome, the Prince of Tarentum, and the Condottiere Jacopo Piccinino, were accomplices and supporters of Tiburzio. Indeed, when we think of the booty which was accumulated in the palaces of wealthy prelates—the conspirators had the Cardinal of Aquileia especially in view—we are surprised that, in an almost unguarded city, such attempts were not more frequent and more successful. It was not without reason that Pius II. preferred to reside anywhere rather than in Rome, and even Paul II.229 was exposed to no small anxiety through a plot formed by some discharged abbreviators, who, under the command of Platina, besieged the Vatican for twenty days. The Papacy must sooner or later have fallen a victim to such enterprises, if it had not stamped out the aristocratic factions under whose protection these bands of robbers grew to a head.
This task was undertaken by the terrible Sixtus IV. He was the first Pope who had Rome and the neighbourhood thoroughly under his control, especially after his successful attack on the House of Colonna, and consequently, both in his Italian policy and in the internal affairs of the Church, he could venture to act with a defiant audacity, and to set at nought the complaints and threats to summon a council which arose from all parts of Europe. He supplied himself with the necessary funds by simony, which suddenly grew to unheard-of proportions, and which extended from the appointment of cardinals down to the granting of the smallest favours.230 Sixtus himself had not obtained the papal dignity without recourse to the same means.
A corruption so universal might sooner or later bring disastrous consequences on the Holy See, but they lay in the uncertain future. It was otherwise with nepotism, which threatened at one time to destroy the Papacy altogether. Of all the ‘nipoti,’ Cardinal Pietro Riario enjoyed at first the chief and almost exclusive favour of Sixtus. He soon drew upon him the eyes of all Italy,231 partly by the fabulous luxury of his life, partly through the reports which were current of his irreligion and his political plans. He bargained with Duke Galeazzo Maria of Milan (1473), that the latter should become King of Lombardy, and then aid him with money and troops to return to Rome and ascend the papal throne; Sixtus, it appears, would have voluntarily yielded it to him.232 This plan, which, by making the Papacy hereditary, would have ended in the secularization of the papal state, failed through the sudden death of Pietro. The second ‘nipote,’ Girolamo Riario, remained a layman, and did not seek the Pontificate. From this time the ‘nipoti,’ by their endeavours to found principalities for themselves, became a new source of confusion to Italy. It had already happened that the Popes tried to make good their feudal claims on Naples in favour of their relatives;233 but since the failure of Calixtus III. such a scheme was no longer practicable, and Girolamo Riario, after the attempt to conquer Florence (and who knows how many other places) had failed, was forced to content himself with founding a state within the limits of the papal dominions themselves. This was, in so far, justifiable, as Romagna, with its princes and civic despots, threatened to shake off the papal supremacy altogether, and ran the risk of shortly falling a prey to Sforza or the Venetians, when Rome interfered to prevent it. But who, at times and in circumstances like these, could guarantee the continued obedience of ‘nipoti’ and their descendants, now turned into sovereign rulers, to Popes with whom they had no further concern? Even in his lifetime the Pope was not always sure of his own son or nephew, and the temptation was strong to expel the ‘nipote’ of a predecessor and replace him by one of his own. The reaction of the whole system on the Papacy itself was of the most serious character; all means of compulsion, whether temporal or spiritual, were used without scruple for the most questionable ends, and to these all the other objects of the Apostolic See were made subordinate. And when they were attained, at whatever cost of revolutions and proscriptions, a dynasty was founded which had no stronger interest than the destruction of the Papacy.
At the death of Sixtus, Girolamo was only able to maintain himself in his usurped principality of Forli and Imola by the utmost exertions of his own, and by the aid of the House of Sforza. He was murdered in 1488. In the conclave (1484) which followed the death of Sixtus—that in which Innocent VIII. was elected—an incident occurred which seemed to furnish the Papacy with a new external guarantee. Two cardinals, who, at the same time, were princes of ruling houses, Giovanni d’Aragona, son of King Ferrante, and Ascanio Sforza, brother of the Moor, sold their votes with the most shameless effrontery;234 so that, at any rate, the ruling houses of Naples and Milan became interested, by their participation in the booty, in the continuance of the papal system. Once again, in the following Conclave, when all the cardinals but five sold themselves, Ascanio received enormous sums in bribes, not without cherishing the hope that at the next election he would himself be the favoured candidate.
