With these ordinations, civil and military, the Florentines established their liberty. Nor is it possible to imagine the power and authority Florence in a short time acquired. She became not only the head of Tuscany, but was enumerated among the first cities of Italy, and would have attained greatness of the most exalted kind, had she not been afflicted with the continual divisions of her citizens. They remained under the this government ten years, during which time they compelled the people of Pistoria, Arezzo, and Sienna, to enter into league with them; and returning with the army from Sienna, they took Volterra, destroyed some castles, and led the inhabitants to Florence. All these enterprises were effected by the advice of the Guelphs, who were much more powerful than the Ghibellines, for the latter were hated by the people as well on account of their haughty bearing while in power, during the time of Frederick, as because the church party was in more favor than that of the emperor; for with the aid of the church they hoped to preserve their liberty, but, with the emperor, they were apprehensive of losing it.
The Ghibellines, in the meantime, finding themselves divested of authority, could not rest, but watched for an occasion of repossessing the government; and they thought the favorable moment come, when they found that Manfred, son of Frederick, had made himself sovereign of Naples, and reduced the power of the church. They, therefore, secretly communicated with him, to resume the management of the state, but could not prevent their proceedings from coming to the knowledge of the Anziani, who immediately summoned the Uberti to appear before them; but instead of obeying, they took arms and fortified themselves in their houses. The people, enraged at this, armed themselves, and with the assistance of the Guelphs, compelled them to quit the city, and, with the whole Ghibelline party, withdraw to Sienna. They then asked assistance of Manfred king of Naples, and by the able conduct of Farinata degli Uberti, the Guelphs were routed by the king's forces upon the river Arbia, with so great slaughter, that those who escaped, thinking Florence lost, did not return thither, but sought refuge at Lucca.
Manfred sent the Count Giordano, a man of considerable reputation in arms, to command his forces. He after the victory, went with the Ghibellines to Florence, and reduced the city entirely to the king's authority, annulling the magistracies and every other institution that retained any appearance of freedom. This injury, committed with little prudence, excited the ardent animosity of the people, and their enmity against the Ghibellines, whose ruin it eventually caused, was increased to the highest pitch. The necessities of the kingdom compelling the Count Giordano to return to Naples, he left at Florence as regal vicar the Count Guido Novallo, lord of Casentino, who called a council of Ghibellines at Empoli. There it was concluded, with only one dissenting voice, that in order to preserve their power in Tuscany, it would be necessary to destroy Florence, as the only means of compelling the Guelphs to withdraw their support from the party of the church. To this so cruel a sentence, given against such a noble city, there was not a citizen who offered any opposition, except Farinata degli Uberti, who openly defended her, saying he had not encountered so many dangers and difficulties, but in the hope of returning to his country; that he still wished for what he had so earnestly sought, nor would he refuse the blessing which fortune now presented, even though by using it, he were to become as much an enemy of those who thought otherwise, as he had been of the Guelphs; and that no one need be afraid the city would occasion the ruin of their country, for he hoped that the valor which had expelled the Guelphs, would be sufficient to defend her. Farinata was a man of undaunted resolution, and excelled greatly in military affairs: being the head of the Ghibelline party, and in high estimation with Manfred, his authority put a stop to the discussion, and induced the rest to think of some other means of preserving their power.
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.
Count Guido proposed to lay a tax upon the citizens for the support of the soldiery; but during the discussion found so much difficulty, that he did not dare to use force to obtain it; and thinking he had now lost the government, called together the leaders of the Ghibellines, and they determined to wrest from the people those powers which they had with so little prudence conceded. When they thought they had sufficient force, the thirty-six being assembled, they caused a tumult to be raised, which so alarmed them that they retired to their houses, when suddenly the banners of the Arts were unfurled, and many armed men drawn to them. These, learning that Count Guido and his followers were at St. John's, moved toward the Holy Trinity, and chose Giovanni Soldanieri for their leader. The count, on the other hand, being informed where the people were assembled, proceeded in that direction; nor did the people shun the fight, for, meeting their enemies where now stands the residence of the Tornaquinci, they put the count to flight, with the loss of many of his followers. Terrified with this result, he was afraid his enemies would attack him in the
