again the lapse of a few years was sufficient to show their weakness. This brought disorder and violence into the town, and led to the recovery of political power by the citizen class at the very moment when the efforts of the Imperialists to reconquer their old position in Italy more than ever demanded strength in the popular element of the governing power. CHAPTER II. THE FOURTEENTH CENTURY—RULE OF THE ALBIZZI—GIOVANNO D’AVERARDO DE’ MEDICI. THE sanguinary conflict of Campaldino was fought, in 1289, in the plain on the Arno which is overlooked by Poppi, the principal place in the Tuscan valley of the Casentino, where stood the stronghold of those Counts Guidi, who were the protectors of the Guelf cause when brought to its lowest ebb by the war of the Vespers. Two years after the battle, in 1291, Ardingo de’ Medici first sat among the Priors of Florence, and in 1296, when the office was still a new one, he was appointed Gonfalonier, as also was his brother Guccio three years later. Of the last-named there exists a memento, the oldest relating to the family, in the sarcophagus that once held his bones and was immured in the outer wall of the Baptistery. This antique, which is carved in relief with a representation of the chase in Calydon, was placed in the courtyard of the Medici palace, and bears on its modern cover the arms of the family, as well as those of the Guild of Woolstaplers, to which the Medici belonged. Thus, at the end of the thirteenth century we see members of the family in a position of respectable burghers in the enjoyment of civic honours. Nothing remarkable is heard of them until the middle of the fourteenth century. They formed part, in their numerous branches, of the large family of the people who were increasing more and more their trade and manufactures, and shared on an equal footing in the government of their city. In the second half of the century two of them became remarkable in different ways, Averardo, called Bicci, son of Salvestro, called Chiarissimo, and Salvestro, son of Alamanno, two cousins in the fourth degree. Of the first we shall speak presently. Salvestro played the chief part in a transaction that shed a lurid light on the history of Florence of that period, but which was the beginning of that influence which ended in the sole supremacy of the Medici.
