The Cerchi and the Donati were, for riches, nobility, and the number and influence of their followers, perhaps the two most distinguished families in Florence. Being neighbors, both in the city and the country, there had arisen between them some slight displeasure, which, however, had not occasioned an open quarrel, and perhaps never would have produced any serious effect if the malignant humors had not been increased by new causes. Among the first families of Pistoia was the Cancellieri. It happened that Lore, son of Gulielmo, and Geri, son of Bertacca, both of this family, playing together, and coming to words, Geri was slightly wounded by Lore. This displeased Gulielmo; and, designing by a suitable apology to remove all cause of further animosity, he ordered his son to go to the house of the father of the youth whom he had wounded and ask pardon. Lore obeyed his father; but this act of virtue failed to soften the cruel mind of Bertacca, and having caused Lore to be seized, in order to add the greatest indignity to his brutal act, he ordered his servants to chop off the youth’s hand upon a block used for cutting meat upon, and then said to him, “Go to thy father, and tell him that sword wounds are cured with iron and not with words.”

The unfeeling barbarity of this act so greatly exasperated Gulielmo that he ordered his people to take arms for his revenge. Bertacca prepared for his defense, and not only that family, but the whole city of Pistoia, became divided. And as the Cancellieri were descended from a Cancelliere who had had two wives, of whom one was called Bianca (white), one party was named by those who were descended from her BIANCA; and the other, by way of greater distinction, was called NERA (black). Much and long-continued strife took place between the two, attended with the death of many men and the destruction of much property; and not being able to effect a union among themselves, but weary of the evil, and anxious either to bring it to an end, or, by engaging others in their quarrel, increase it, they came to Florence, where the Neri, on account of their familiarity with the Donati, were favored by Corso, the head of that family; and on this account the Bianchi, that they might have a powerful head to defend them against the Donati, had recourse to Veri de Cerchi, a man in no respect inferior to Corso.

This quarrel, and the parties in it, brought from Pistoia, increased the old animosity between the Cerchi and the Donati, and it was already so manifest, that the Priors and all well-disposed men were in hourly apprehension of its breaking out, and causing a division of the whole city. They therefore applied to the pontiff, praying that he would interpose his authority between these turbulent parties, and provide the remedy which they found themselves unable to furnish. The pope sent for Veri, and charged him to make peace with the Donati, at which Veri exhibited great astonishment, saying that he had no enmity against them, and that as pacification presupposes war, he did not know, there being no war between them, how peacemaking could be necessary. Veri having returned from Rome without anything being effected, the rage of the parties increased to such a degree, that any trivial accident seemed sufficient to make it burst forth, as indeed presently happened.

It was in the month of May, during which, and upon holidays, it is the custom of Florence to hold festivals and public rejoicings throughout the city. Some youths of the Donati family, with their friends, upon horseback, were standing near the church of the Holy Trinity to look at a party of ladies who were dancing; thither also came some of the Cerchi, like the Donati, accompanied with many of the nobility, and, not knowing that the Donati were before them, pushed their horses and jostled them; thereupon the Donati, thinking themselves insulted, drew their swords, nor were the Cerchi at all backward to do the same, and not till after the interchange of many wounds, they separated. This disturbance was the beginning of great evils; for the whole city became divided, the people as well as the nobility, and the parties took the names of the Bianchi and the Neri. The Cerchi were at the head of the Bianchi faction, to which adhered the Adimari, the Abati, a part of the Tosinghi, of the Bardi, of the Rossi, of the Frescobaldi, of the Nerli, and of the Manelli; all the Mozzi, the Scali, Gherardini, Cavalcanti, Malespini, Bostichi, Giandonati, Vecchietti, and Arrigucci. To these were joined many families of the people, and all the Ghibellines then in Florence, so that their great numbers gave them almost the entire government of the city.

The Donati, at the head of whom was Corso, joined the Nera party, to which also adhered those members of the above-named families who did not take part with the Bianchi; and besides these, the whole of the Pazzi, the Bisdomini, Manieri, Bagnesi, Tornaquinci, Spini, Buondelmonti, Gianfigliazzi, and the Brunelleschi. Nor did the evil confine itself to the city alone, for the whole country was divided upon it, so that the Captains of the Six Parts, and whoever were attached to the Guelphic party or the well-being of the republic, were very much afraid that this new division would occasion the destruction of the city, and give new life to the Ghibelline faction. They, therefore, sent again to Pope Boniface, desiring that, unless he wished that city which had always been the shield of the church should either be ruined or become Ghibelline, he would consider some means for her relief. The pontiff thereupon sent to Florence, as his legate, Cardinal Matteo d’Acquasparta, a Portuguese, who, finding the Bianchi, as the most powerful, the least in fear, not quite submissive to him, he interdicted the city, and left it in anger, so that greater confusion now prevailed than had done previously to his coming.

The minds of men being in great excitement, it happened that at a funeral which many of the Donati and the Cerchi attended, they first came to words and then to arms, from which, however, nothing but merely tumult resulted at the moment. However, having each retired to their houses, the Cerchi determined to attack the Donati, but, by the valor of Corso, they were repulsed and great numbers of them wounded. The city was in arms. The laws and the Signory were set at nought by the rage of the nobility, and the best and wisest citizens were full of apprehension. The Donati and their followers, being the least powerful, were in the greatest fear, and to provide for their safety they called together Corso, the Captains of the Parts, and the other leaders of the Neri, and resolved to apply to the pope to appoint some personage of royal blood, that he might reform Florence; thinking by this means to overcome the Bianchi. Their meeting and determination became known to the Priors, and the adverse party represented it as a conspiracy against the liberties of the republic. Both parties being in arms, the Signory, one of whom at that time was the poet Dante, took courage, and from his advice and prudence, caused the people to rise for the preservation of order, and being joined by many from the country, they compelled the leaders of both parties to lay aside their arms, and banished Corso, with many of the Neri. And as an evidence of the impartiality of their motives, they also banished many of the Bianchi, who, however, soon afterward, under pretense of some justifiable cause, returned.

Corso and his friends, thinking the pope favorable to their party, went to Rome and laid their grievances before him, having previously forwarded a statement of them in writing. Charles of Valois, brother of the king of France, was then at the papal court, having been called into Italy by the king of Naples, to go over into Sicily. The pope, therefore, at the earnest prayers of the banished Florentines, consented to send Charles to Florence, till the season suitable for his going to Sicily should arrive. He therefore came, and alth............
