Wherefore in the selfsame year there began in Florence dissension and great war among the citizens, the worst that had ever been in Florence; and this was by reason of too great prosperity and repose, together with pride and ingratitude; forasmuch as the house of the Uberti, which were the most powerful and the greatest citizens of Florence, with their allies, both magnates and popolari, began war against the Consuls (which were the lords and rulers of the commonwealth for a certain time and under certain ordinances), from envy of the Government, which was not to their mind; and the war was so fierce and unnatural that well-nigh every day, or every other day, the citizens fought against one another in divers parts of the city, from district to district, according as the factions were, and as they had fortified their towers, whereof there was great number in the city, in height 100 or 120 cubits. And in those times, by reason of the said war, many towers were newly fortified by the communities of the districts, from the common funds of the neighbourhood, which were called Towers of the Fellowships, and upon them were set engines to shoot forth one at another, and the city was barricaded in many places; and this plague endured more than two years, and many died by reason thereof, and much peril and hurt was brought upon the city; but this war among the citizens became so much of use and wont that one day they would be fighting, and the next day they would be eating and drinking together, and telling tales of one another's valour and prowess in these battles; and at last they ceased fighting, in that it irked them for very weariness, and they made peace, and the Consuls remained in their government; albeit, in the end they begot and then brought forth the accursed factions, which were afterwards in Florence, as hereafter in due time we will make mention.
