Florence was at this time in a very unhappy condition; for the great Guelphic families had become insolent, and set aside the authority of the magistrates; so that murders and other atrocities were daily committed, and the perpetrators escaped unpunished, under the protection of one or other of the nobility. The leaders of the people, in order to restrain this insolence, determined to recall those who had been expelled, and thus gave the legate an opportunity of uniting the city. The Ghibellines returned, and, instead of twelve governors, fourteen were appointed, seven for each party, who held their office one year, and were to be chosen by the pope. The Florentines lived under this government two years, till the pontificate of Martin, who restored to Charles all the authority which had been taken from him by Nicholas, so that parties were again active in Tuscany; for the Florentines took arms against the emperor's governor, and to deprive the Ghibellines of power, and restrain the nobility, established a new form of government. This was in the year 1282, and the companies of the Arts, since magistrates had been appointed and colors given to them, had acquired so great influence, that of their own authority they ordered that, instead of fourteen citizens, three should be appointed and called Priors, to hold the government of the republic two months, and chosen from either the people or the nobility. After the expiration of the first magistracy they were augmented to six, that one might be chosen from each sixth of the city, and this number was preserved till the year 1342, when the city was divided into quarters, and the Priors became eight, although upon some occasions during the interim they were twelve.
This government, as will be seen hereafter, occasioned the ruin of the nobility; for the people by various causes excluded them from all participation in it, and then trampled upon them without respect. The nobles at first, owing to their divisions among themselves, made no opposition; and each being anxious to rob the other of influence in the state, they lost it altogether. To this government a palace was given, in which they were to reside constantly, and all requisite officers were appointed; it having been previously the custom of councils and magistrates to assemble in churches. At first they were only called Priors, but to increase their distinction the word signori, or lords, was soon afterward adopted. The Florentines remained for some time in domestic quiet, during which they made war with the Aretins for having expelled the Guelphs, and obtained a complete victory over them at Campaldino. The city being increased in riches and population, it was found expedient to extend the walls, the circle of which was enlarged to the extent it at present remains, although its diameter was previously only the space between the old bridge and the church of St. Lorenzo.
