In this unhappy state, the people not knowing what to do, Giano della Bella, of a very noble family, and a lover of liberty, encouraged the heads of the Arts to reform the constitution of the city; and by his advice it was ordered that the Gonfalonier should reside with the Priors, and have four thousand men at his command. They deprived the nobility of the right to sit in the Signory. They condemned the associates of a criminal to the same penalty as himself, and ordered that public report should be taken as evidence. By these laws, which were called the ordinations of justice, the people acquired great influence, and Giano della Bella not a small share of trouble; for he was thoroughly hated by the great, as the destroyer of their power, while the opulent among the people envied him, for they thought he possessed too great authority. This became very evident upon the first occasion that presented itself.
It happened that a man from the class of the people was killed in a riot, in which several of the nobility had taken a part, and among the rest Corso Donati, to whom, as the most forward of the party, the death was attributed. He was, therefore, taken by the captain of the people, and whether he was really innocent of the crime or the Capitano was afraid of condemning him, he was acquitted. This acquittal displeased the people so much, that, seizing their arms, they ran to the house of Giano della Bella, to beg that he would compel the execution of those laws which he had himself made. Giano, who wished Corso to be punished, did not insist upon their laying down their arms, as many were of opinion he ought to have done, but advised them to go to the Signory, complain of the fact, and beg that they would take it into consideration. The people, full of wrath, thinking themselves insulted by the Capitano and abandoned by Giano della Bella, instead of going to the Signory went to the palace of the Capitano, of which they made themselves masters, and plundered it.
This outrage displeased the whole city, and those who wished the ruin of Giano laid the entire blame upon him; and as in the succeeding Signory there was an enemy of his, he was accused to the Capitano as the originator of the riot. While the case was being tried, the people took arms, and, proceeding to his house, offered to defend him against the Signory and his enemies. Giano, however, did not wish to put this burst of popular favor to the proof, or trust his life to the magistrates, for he feared the malignity of the latter and the instability of the former; so, in order to remove an occasion for his enemies to injure him, or his friends to offend the laws, he determined to withdraw, deliver his countrymen from the fear they had of him, and, leaving the city which at his own charge and peril he had delivered from the servitude of the great, become a voluntary exile.
After the departure of Giano della Bella the nobility began to entertain hopes of recovering their authority; and judging their misfortune to have arisen from their divisions, they sent two of their body to the Signory, which they thought was favorable to them, to beg they would be pleased to moderate the severity of the laws made against them. As soon as their demand became known, the minds of the people were much excited; for they were afraid the Signors would submit to them; and so, between the desire of the nobility and the jealousy of the people, arms were resorted to. The nobility were drawn together in three places: near the church of St. John, in the New Market, and in the Piazza of the Mozzi, under three leaders, Forese Adimari, Vanni de Mozzi, and Geri Spini. The people assembled in immense numbers, under their ensigns, before the palace of the Signory, which at that time was situated near St. Procolo; and, as they suspected the integrity of the Signory, they added six citizens to their number to take part in the management of affairs.
While both parties were preparing for the fight, some individuals, as well of the people as of the nobility, accompanied by a few priests of respectable character, mingled among them for the purpose of effecting a pacification, reminding the nobility that their loss of power, and the laws which were made against them, had been occasioned by their haughty conduct, and the mischievous tendency of their proceedings; that resorting to arms to recover by force what they had lost by illiberal measures and disunion, would tend to the destruction of their country and increase the difficulties of their own position; that they should bear in mind that the people, both in riches, numbers, and hatred, were far stronger than they; and that their nobility, on account of which they assumed to be above others, did not contribute to win battles, and would be found, when they came to arms, to be but an empty name, and insufficient to defend them against so many. On the other hand, they reminded the people that it is not prudent to wish always to have the last blow; that it is an injudicious step to drive men to desperation, for he who is without hope is also without fear; that they ought not to forget that in the wars the nobility had always done honor to the country, and therefore it was neither wise nor just to pursue them with so much bitterness; and that although the nobility could bear with patience the loss of the supreme magistracy, they could not endure that, by the existing laws, it should be in the power of everyone to drive them from their country; and, therefore, it would be well to qualify these laws, and, in furtherance of so good a result, be better to lay down their arms than, trusting to numbers, try the fortune of a battle; for it is often seen that the many are overcome by the few. Variety of opinion was found among the people; many wished to decide the question by arms at once, for they were assured it would have to be done some time, and that it would be better to do so then than delay till the enemy had acquired greater strength; and that if they thought a mitigation of the laws would satisfy them, that then they would be glad to comply, but that the pride of the nobility was so great they would not submit unless they were compelled. To many others, who were more peaceable and better disposed, it appeared a less evil to qualify the laws a little than to come to battle; and their opinion prevailing, it was provided that no accusation against the nobility could be received unless supported with sufficient testimony.
Although arms were laid aside, both parties remained full of suspicion, and each fortified itself with men and places of strength. The people reorganized the government, and lessened the number of its officers, to which measure they were induced by finding that the Signors appointed from the families, of which the following were the heads, had been favorable to the nobility, viz.: the Mancini, Magalotti, Altoviti, Peruzzi, and Cerretani. Having settled the government, for the greater magnificence and security of the Signory, they laid the foundation of their palace; and to make space for the piazza, removed the houses that had belonged to the Uberti; they also at the same period commenced the public prisons. These buildings were completed in a few years; nor did our city ever enjoy a greater state of prosperity than in those times: filled with men of great wealth and reputation; possessing within her walls 30,000 men capable of bearing arms, and in the country 70,000, while the whole of Tuscany, either as subjects or friends, owed obedience to Florence. And although there might be some indignation and jealousy between the nobility and the people, they did not produce any evil effect, but all lived together in unity and peace. And if this peace had not been disturbed by internal enmities there would have been no cause of apprehension whatever, for the city had nothing to fear either from the empire or from those citizens whom political reasons kept from their homes, and was in condition to meet all the states of Italy with her own forces. The evil, however, which external powers could not effect, was brought about by those within.
