The Lucchese being threatened with the anger of the count, for affording refuge to the Guelphs after the battle of the Arbia, could allow them to remain no longer; so leaving Lucca, they went to Bologna, from whence they were called by the Guelphs of Parma against the Ghibellines of that city, where, having overcome the enemy, the possessions of the latter were assigned to them; so that having increased in honors and riches, and learning that Pope Clement had invited Charles of Anjou to take the kingdom from Manfred, they sent ambassadors to the pope to offer him their services. His holiness not only received them as friends, but gave them a standard upon which his insignia were wrought. It was ever after borne by the Guelphs in battle, and is still used at Florence. Charles having taken the kingdom from Manfred, and slain him, to which success the Guelphs of Florence had contributed, their party became more powerful, and that of the Ghibellines proportionately weaker. In consequence of this, those who with Count Novello governed the city, thought it would be advisable to attach to themselves, with some concession, the people whom they had previously aggravated with every species of injury; but these remedies which, if applied before the necessity came would have been beneficial, being offered when they were no longer considered favors, not only failed of producing any beneficial results to the donors, but hastened their ruin. Thinking, however, to win them to their interests, they restored some of the honors of which they had deprived them. They elected thirty-six citizens from the higher rank of the people, to whom, with two cavaliers, knights or gentlemen, brought from Bologna, the reformation of the government of the city was confided. As soon as they met, they classed the whole of the people according to their arts or trades, and over each art appointed a magistrate, whose duty was to distribute justice to those placed under him. They gave to each company or trade a banner, under which every man was expected to appear armed, whenever the city required it. These arts were at first twelve, seven major and five minor. The minor arts were afterward increased to fourteen, so that the whole made, as at present, twenty-one. The thirty-six reformers also effected other changes for the common good.
