The death of this prince infused redoubled energy into the Florentine dissensions, and caused them to produce more prompt effects than they would otherwise have done. Upon the demise of Cosmo, his son Piero, being heir to the wealth and government of his father, called to his assistance Diotisalvi Neroni, a man of great influence and the highest reputation, in whom Cosmo reposed so much confidence that just before his death he recommended Piero to be wholly guided by him, both with regard to the government of the city and the management of his fortune. Piero acquired Diotisalvi with the opinion Cosmo entertained of him, and said that as he wished to obey his father, though now no more, as he always had while alive, he should consult him concerning both his patrimony and the city. Beginning with his private affairs, he caused an account of all his property, liabilities, and assets, to be placed in Diotisalvi's hands, that, with an entire acquaintance with the state of his affairs, he might be able to afford suitable advice, and the latter promised to use the utmost care. Upon examination of these accounts the affairs were found to be in great disorder, and Diotisalvi, instigated rather by his own ambition than by attachment to Piero or gratitude to Cosmo, thought he might without difficulty deprive him of both the reputation and the splendor which his father had left him as his inheritance. In order to realize his views, he waited upon Piero, and advised him to adopt a measure which, while it appeared quite correct in itself, and suitable to existing circumstances, involved a consequence destructive to his authority. He explained the disorder of his affairs, and the large amount of money it would be necessary to provide, if he wished to preserve his influence in the state and his reputation of wealth; and said there was no other means of remedying these disorders so just and available as to call in the sums which his father had lent to an infinite number of persons, both foreigners and citizens; for Cosmo, to acquire partisans in Florence and friends abroad, was extremely liberal of his money, and the amount of loans due to him was enormous. Piero thought the advice good, because he was only desirous to repossess his own property to meet the demands to which he was liable; but as soon as he had ordered those amounts to be recalled, the citizens, as if he had asked for something to which he had no kind of claim, took great offense, loaded him with opprobrious expressions, and accused him of being avaricious and ungrateful.
Diotisalvi, noticing the popular excitement against Piero, occasioned by his own advice, obtained an interview with Luca Pitti, Agnolo Acciajuoli, and Niccolo Soderini, and they resolved to unite their efforts to deprive him both of the government and his influence. Each was actuated by a different motive; Luca Pitti wished to take the position Cosmo had occupied, for he was now become so great, that he disdained to submit to Piero; Diotisalvi Neroni, who knew Luca unfit to be at the head of a government, thought that of necessity on Piero's removal, the whole authority of the state would devolve upon himself; Niccolo Soderini desired the city to enjoy greater liberty, and for the laws to be equally binding upon all. Agnolo Acciajuoli was greatly incensed against the Medici, for the following reasons: his son, Raffaello, had some time before married Alessandra de' Bardi, and received with her a large dowry. She, either by her own fault or the misconduct of others, suffered much ill-treatment both from her father-in-law and her husband, and in consequence Lorenzo d' Ilarione, her kinsman, out of pity for the girl, being accompanied by several armed men, took her away from Agnolo's house. The Acciajuoli complained of the injury done them by the Bardi, and the matter was referred to Cosmo, who decided that the Acciajuoli should restore to Alessandra her fortune, and then leave it to her choice either to return to her husband or not. Agnolo thought Cosmo had not, in this instance, treated him as a friend; and having been unable to avenge himself on the father, he now resolved to do his utmost to ruin the son. These conspirators, though each was influenced by a different motive from the rest, affected to have only one object in view, which was that the city should be governed by the magistrates, and not be subjected to the counsels of a few individuals. The odium against Piero, and opportunities of injuring him, were increased by the number of merchants who failed about this time; for it was reported that he, in having, quite unexpectedly to all, resolved to call in his debts, had, to the disgrace and ruin of the city, caused them to become insolvent. To this was added his endeavor to obtain Clarice degli Orsini as wife of Lorenzo, his eldest son; and hence his enemies took occasion to say, it was quite clear, that as he despised a Florentine alliance, he no longer considered himself one of the people, and was preparing to make himself prince; for he who refuses his fellow-citizens as relatives, desires to make them slaves, and therefore cannot expect to have them as friends. The leaders of the sedition thought they had the victory in their power; for the greater part of the citizens followed them, deceived by the name of liberty which they, to give their purpose a graceful covering, adopted upon their ensigns.
