He stood not merely at the head of the Florentine nobility, but at the head of the great Guelph organization which extended from city to city throughout Tuscany--a league with its own leaders, its own policy, its own treasure. In the attempt to seize this treasure for the general service of the State the most popular of Florentine leaders, Giano della Bella, had been foiled and driven into exile. An honest attempt to secure the peace of the city by the banishment of Corso and his friends brought about the exile of Dante. It is plain that powerless as they were before the united forces of the whole people the nobles were strong enough by simply biding their time and availing themselves of popular divisions to crush one opponent after another. And yet the struggle against them was one of life and death for the city. No atom of the new civilization, the new spirit of freedom or humanity, seems to have penetrated among them. Behind the gloomy walls of their city fortresses they remained the mere murderous tyrants of a brutal feudalism. "I counsel, lords, that we free ourselves from this slavery," cried Berto Frescobaldi to his brother nobles in the church of San Jacopo; "let us arm ourselves and run on to the Piazza, and there kill friend and foe alike as many as we find, so that neither we nor our children be ever subject to them more." Those who, like Sismondi, censure the sternness of the laws which pressed upon the nobles forget what wild beasts they were intended to hold down. Their outbreaks were the blind outbreaks of mere ruffians. The victory of Corso over Dante and the wiser citizens was followed by a carnival of bloodshed, firing of houses, pillage and lawlessness which wrings from Dino curses as bitter as those of the 'Inferno.'
