About the same time, Uguccione lost the sovereignty of Lucca and of Pisa, and Castruccio Castracani, a citizen of Lucca, became lord of them, who, being a young man, bold and fierce, and fortunate in his enterprises, in a short time became the head of the Ghibellines in Tuscany. On this account the discords among the Florentines were laid aside for some years, at first to abate the increasing power of Castruccio, and afterward to unite their means for mutual defense against him. And in order to give increased strength and efficacy to their counsels, the Signory appointed twelve citizens whom they called Buonomini, or good men, without whose advice and consent nothing of any importance could be carried into effect. The conclusion of the sovereignty of King Robert being come, the citizens took the government into their own hands, reappointed the usual rectors and magistracies, and were kept united by the dread of Castruccio, who, after many efforts against the lords of Lunigiano, attacked Prato, to the relief of which the Florentines having resolved to go, shut up their shops and houses, and proceeded thither in a body, amounting to twenty thousand foot and one thousand five hundred horse. And in order to reduce the number of Castruccio’s friends and augment their own, the Signory declared that every rebel of the Guelphic party who should come to the relief of Prato would be restored to his country; they thus increased their army with an addition of four thousand men. This great force being quickly brought to Prato, alarmed Castruccio so much, that without trying the fortune of battle, he retired toward Lucca. Upon this, disturbances arose in the Florentine camp between the nobility and the people, the latter of whom wished to pursue the foe and destroy him; the former were for returning home, saying they had done enough for Prato in hazarding the safety of Florence on its account, which they did not regret under the circumstances, but now, that necessity no longer existing, the propriety of further risk ceased also, as there was little to be gained and much to lose. Not being able to agree, the question was referred to the Signory, among whom the difference of opinion was equally great; and as the matter spread throughout the city, the people drew together, and used such threatening language against the nobility that they, being apprehensive for their safety, yielded; but the resolution being adopted too late, and by many unwillingly, gave the enemy time to withdraw in safety to Lucca.

This unfortunate circumstance made the people so indignant against the great that the Signory refused to perform the promise made to the exiles, and the latter, anticipating the fact, determined to be beforehand, and were at the gates of Florence to gain admittance into the city before the rest of the forces; but their design did not take effect, for their purpose being foreseen, they were repulsed by those who had remained at home. They then endeavored to acquire by entreaty what they had failed to obtain by force; and sent eight men as ambassadors to the Signory, to remind them of the promise given, and of the dangers they had undergone, in hope of the reward which had been held out to them. And although the nobility, who felt the obligation on account of their having particularly undertaken to fulfill the promise for which the Signory had bound themselves, used their utmost exertion in favor of the exiles, so great was the anger of the multitude on account of their only partial success against Castruccio, that they could not obtain their admission. This occasioned cost and dishonor to the city; for many of the nobility, taking offense at this proceeding, endeavored to obtain by arms that which had been refused to their prayers, and agreed with the exiles that they should come armed to the city, and that those within would arm themselves in their defense. But the affair was discovered before the appointed day arrived, so that those without found the city in arms, and prepared to resist them. So completely subdued were those within, that none dared to take arms; and thus the undertaking was abandoned, without any advantage having been obtained by the party. After the departure of the exiles it was determined to punish those who had been instrumental in bringing them to the city; but, although everyone knew who were the delinquents, none ventured to name and still less to accuse them. It was, therefore, resolved that in order to come at the truth, everyone should write the names of those he believed to be guilty, and present the writing secretly to the Capitano. By this means, Amerigo Donati, Teghiajo, Frescobaldi, and Lotteringo Gherardini were accused; but, the judges being more favorably disposed to them than, perhaps, their misdeeds deserved, each escaped by paying a fine.

The tumults which arose in Florence from the coming of the rebels to the gates, showed that one leader was insufficient for the companies of the people; they, therefore, determined that in future each should have three or four; and to every Gonfalonier two or three Pennonieri (pennon bearers) were added, so that if the whole body were not drawn out, a part might operate under one of them. And as happens in republics, after any disturbance, some old laws are annulled and others renewed, so on this occasion, as it had been previously customary to appoint the Signory for a time only, the then existing Signors and the Colleagues, feeling themselves possessed of sufficient power, assumed the authority to fix upon the Signors that would have to sit during the next forty months, by putting their names into a bag or purse, and drawing them every two months. But, before the expiration of the forty months, many citizens were jealous that their names had not been deposited among the rest, and a new emborsation was made. From this be............
