II.

Thus, throughout all these wars, in which the influence of Pope and emperor was felt on this or the other side, we are enabled to trace the gradual formation of parties in Tuscany, and to witness the process by which the political and commercial supremacy of Florence was built up. Her present rivals, Sienna and Pisa, both adhere to the Empire; whereas Florence clings more and more closely to the Church. Pisa shuts her out from the sea: hence the origin of their mutual rivalry and continual strife. How, indeed, could war be avoided, when the commercial power of Florence felt the increasingly imperative need of free access to the coast? Sienna, on the other hand, competed with Florence by trying to get all the affairs of the Roman curia into the hands of its own bankers, those affairs being so numerous and lucrative as to enrich all concerned with them. These continual jealousies invariably urged Pisa and Sienna to favour the Empire. Lucca, as the rival of Pisa, inclined towards Florence, and became Guelph. Pistoia, planted between two Guelph cities, and continually menaced by them, naturally adopted the Ghibelline cause. Thus, the division of parties in Tuscany afterwards reacted on the formation of Florentine sects, and as the latter began to assume a more general character, through the growing influence of Frederic II. in Italy, they adopted the German names of Guelphs and Ghibellines. The Florentine Republic, having triumphed over Pisa, Sienna, and Pistoia, was virtually the chief power in Tuscany; but had one danger to face, in the possible augmentation of Frederic's power. Frederic II. was the enemy of the Pope, who had excommunicated him, and of all Guelphs! He had gone away for a time to lead the Crusade in the East; was now in Germany engaged in a struggle with his rebellious son, and all this had greatly advanced the fortunes of Florence. But he was about to return to Italy, and his presence might again embolden the foes of the Republic.

Meanwhile, under the rule of successive Podestà, Florence had prospered in war, and devoted times of peace to internal organisation and embellishment. At the instance of the Podestà Torello da Strada (1233) all the male inhabitants of the contado were summoned to inscribe their names and specify their condition, whether freemen, serfs, or dependents, with a view to ascertaining the real state of the population and providing for its better government. In 1237–38 the Podestà Rubaconte da Mandello built a new bridge over the Arno, which was first designated by his own name of Rubaconte, and afterwards as the Ponte alle Grazie, in honour of an adjoining church. It was also by order of the same Podestà that all the streets of Florence were first paved, and other works completed for the improvement of the public health, or the decoration of the city. Thus a magistrate originally appointed—according to the chroniclers—to do the work of an ordinary judge is seen gradually fulfilling the functions of the head of the Republic. And the patricians over whom he presided daily rose to greater power and daring, and particularly when the arrival of Frederic II. began to encourage the Ghibelline party throughout Italy. In fact, when Brescia was besieged by the Ghibellines in 1237, we find many Florentine nobles in their camp. Every day brought fresh proofs that the emperor might count on many friends and much assistance from Florence. Consequently numerous riots took place, for the Guelph nobles offered violent opposition and joined with the people, which was entirely Guelph.[238] In 1240 we find that three citizens were nominated to collect funds in aid of the Imperial army: surely a strange proceeding in a republic[239] where the mass of the population was thoroughly Guelph! But it is not surprising that such events should have inevitably caused a reaction.

Already in 1246 Frederic II. had appointed his natural son, Frederic of Antioch, vicar-general of Tuscany, and also sent other vicars to Florence to fill the office of Podestà. This aroused discontent on the part of the Guelph nobles, who wished their own faction to regain the upper hand in the city. About this time, 1247, Frederic was in Lombardy,[240] and at almost open war with the Pope, who continued to launch excommunications at him, deprived him of the Imperial title, and stirred enemies from all sides against him. Accordingly, Frederic sent messengers to the Uberti in Florence, advising them that the moment had come for them to assume the government of Florence. Provided they had the courage to fly to arms, his succour would not be long delayed. The Uberti were not deaf to his words. The heads of the chief Ghibelline houses met in council and decided on immediate resort to violence. There was instant division in the city; the Ghibelline aristocracy on one side, the Guelph nobles, with all the people on the other; and the alarm bell was pealed. Fighting went on from street to street, by day and by night, behind barricades, from tower-roofs, and with catapults, rams, and other engines of war. As the popular excitement increased the strife became general. The Ghibellines had the advantage of superior military training; they were confident of receiving reinforcements; and, massed under one leader, took all their orders from the Uberti palaces. The people, on the contrary, fought at random, and were soon surrounded and repulsed. Nevertheless, at one moment their very defeat seemed about to win them the victory. Hard-pressed on all sides, they were gradually driven back towards the chain barricades (serraglio) of the Bagnesi and Guidalotti mansions; and being massed about this defence, fought so vigorously as almost to regain their former position. But just then the Imperial contingent appeared on the scene, and all was lost. The vicar-general Frederic, son of the emperor, entered Florence at the head of sixteen hundred German knights, and made furious charges on the people. The latter opposed a sturdy resistance, prolonging the fight for three days, but it was a vain struggle. The Ghibellines were victorious on all sides, and the emperor could have sent fresh reinforcements if required. One of the most valiant of the Guelphs, Rustico Marignolli, who had borne the standard of the people throughout the mêlée, fell wounded to the death by a shot in the face from a crossbow. Thereupon the leaders of the party finally decided to surrender and fly into exile on Candlemas night (February 2, 1249). All those resolved on flight gathered together fully armed, and taking possession of Marignolli's corpse, bore it away in a solemn procession with a crowd of popolani, and a great show of weapons and torches, to celebrate the funeral at San Lorenzo by night. The bier was carried on the shoulders of the worthiest cavaliers, and the defeated but not dishonoured banner hung trailing from it to the ground. The whole function resembled a pact of vengeance sworn on the body of the dead warrior rather than a mere burial ceremony.

After this the leading Guelphs fled the city and took refuge in neighbouring castles; the same in fact from which, at the cost of much blood, they had once ousted the feudal lords. These latter, having been compelled to settle in the town, had now won their revenge for past injuries. Thirty-six Guelph houses were pulled down: among them the Tosinghi palace in the New Market, a building measuring one hundred and thirty-five feet in height, and faced with many tiers of marble columns. Party hatred reached such a pitch as to justify the belief expressed by many that the Ghibellines had positively decreed the destruction of San Giovanni, because the Guelphs had used that church as a place of assembly. It was affirmed that the victors had undermined the foundations of the adjoining Guardamorto tower, hoping that this might fall down on the temple and crush it. The failure of the attempt was attributed to the fact that the tower had miraculously fallen in another direction. A more credible account is given by Vasari. He says that the Guardamorto was only demolished in order to widen the Piazza, and that Niccolò Pisano, being charged with the work, cut the tower in two and arranged its fall in a way to avoid any damage to the church or neighbouring houses.

At all events, this proved the beginning of the long list of savage reprisals darkening the history of Florence, when the winning faction not only destroyed the dwellings of the defeated, but banished their foes en masse. The Ghibellines were now masters of all, and for their greater security retained the services of Count Giordano Lancia and his eight hundred Germans. It seemed as though the party, being of Teutonic origin, could not yet grasp the reins of government without the support of German soldiery, and could only command the Republic in the emperor's name. This was the final result of admitting the Imperial feudal nobility within the walls of Florence, and allowing them to institute a political and military chief instead of an ordinary judge in the person of the Podestà.
