The only dispute now is whether they descend from a knight who in days of yore received on his shield the blows of a giant’s iron flail, or from a physician who chose for his sign, in his small beginnings, three pills or cupping-glasses. Giambuono’s son Chiarissimo sat in the Council of the Commune in 1201, when an alliance was formed with the town of Siena for the purpose of attacking the castle Semifonte in the Elsethal, which lay between the territories of the two towns, and was soon after destroyed. This was the first step towards the extension of territory and the overthrow of the landed aristocracy. The thirteenth century, at the beginning of which the Medici first stand forward in history, was the period in which the community of Florence, after many vicissitudes, received its definitive form. Just at the time of the first attempts of the Florentines to acquire an independent self-government do we meet with the first of that race which three centuries later strove successfully to transform what had become a powerful republic into a monarchy. The province of Tuscany, divided into two duchies, in the time of the Longobards formed, first under dukes, then under margraves, a part of the Roman Teutonic kingdom, whose dependence on the later powerful emperors, and also on margraves ruling over wide stretches of land to the north of the Apennines, was more nominal than real, yet still existed according to right. In the summer of 1115, after the death of the great Countess Mathilda—daughter and heiress to the last Margrave Bonifacius, who lived mostly in Lucca—first began the freer movement of the Tuscan Commune. At this time the men who afterwards attained to the lordship over the greater part of the country occupied anything but a prominent position. The great changes in the strength and extent of the imperial power in Italy as it was under the last of the Franconians, under Lothair of Saxony, and the two first Hohenstaufen, necessarily affected the position of these Communes. Their form of government under consuls changed just as their dependence or independence of the imperial authority was affected by the prevailing political condition of the empire. The landed nobility, of Germanic origin for the most part, were supported by Frederic Barbarossa against the Commune of Florence, with which several great families, headed by the Uberti, had engaged in a bloody and protracted feud on account of their claims to an authority which was not compatible with consular government. Henry VI. exercised his imperial rights and privileges in Tuscany still more vigorously than his father had done. His brother Philip, invested with this province as a dukedom, maintained a command such as, perhaps, no other vice-emperor had possessed. In a part of the country claimed by the Popes as the patrimony of Mathilda, Philip’s power overcame the Guelfic element which was so much opposed to the ‘Imperium,’ and which in most
