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 although the Bianchi, who then governed, were very apprehensive, still, as the head of the Guelphs, and appointed by the pope, they did not dare to oppose him, and in order to secure his friendship, they gave him authority to dispose of the city as he thought proper.
