Milan, upon recovering from the ruin into which she had been thrown by Frederick Barbarossa, in revenge for her injuries, joined the league formed by the Lombard cities for their common defense; this restrained him, and for awhile preserved alive the interests of the church in Lombardy. In the course of the wars which followed, the family of La Torre became very potent in that city, and their reputation increased so long as the emperor possessed little authority in the province. But Frederick II. coming into Italy, and the Ghibelline party, by the influence of Ezelin having grown powerful, seeds of the same faction sprang up in all the cities. In Milan were the Visconti, who expelled the La Torres; these, however, did not remain out, for by agreement between the emperor and the pope they were restored to their country. For when the pope and his court removed to France, and the emperor, Henry of Luxemburg, came into Italy, with the pretext of going to Rome for his crown, he was received in Milan by Maffeo Visconti and Guido della Torre, who were then the heads of these families. But Maffeo, designing to make use of the emperor for the purpose of expelling Guido, and thinking the enterprise not difficult, on account of the La Torre being of the contrary faction to the imperial, took occasion, from the remarks which the people made of the uncivil behavior of the Germans, to go craftily about and excite the populace to arm themselves and throw off the yoke of these barbarians. When a suitable moment arrived, he caused a person in whom he confided to create a tumult, upon which the people took arms against the Germans. But no sooner was the mischief well on foot, than Maffeo, with his sons and their partisans, ran to Henry, telling him that all the disturbance had been occasioned by the La Torre family, who, not content to remain peaceably in Milan, had taken the opportunity to plunder him, that they might ingratiate themselves with the Guelphs of Italy and become princes in the city; they then bade him be of good cheer, for they, with their party, whenever he wished it, were ready to defend him with their lives. Henry, believing all that Maffeo told him, joined his forces to those of the Visconti, and attacking the La Torre, who were in various parts of the city endeavoring to quell the tumult, slew all upon whom they could lay hands, and having plundered the others of their property, sent them into exile. By this artifice, Maffeo Visconti became a prince of Milan. Of him remained Galeazzo and Azzo; and, after these, Luchino and Giovanni. Giovanni became archbishop of Milan; and of Luchino, who died before him, were left Bernabo and Galeazzo; Galeazzo, dying soon after, left a son called the Count of Virtu, who after the death of the archbishop, contrived the murder of his uncle, Bernabo, became prince of Milan, and was the first who had the title of duke. The duke left Filippo and Giovanmaria Angelo, the latter of whom being slain by the people of Milan, the state fell to Filippo; but he having no male heir, Milan passed from the family of Visconti to that of Sforza, in the manner to be related hereafter.
But to return to the point from which we deviated. The Emperor Louis, to add to the importance of his party and to receive the crown, came into Italy; and being at Milan, as an excuse for taking money of the Milanese, he pretended to make them free and to put the Visconti in prison; but shortly afterwards he released them, and, having gone to Rome, in order to disturb Italy with less difficulty, he made Piero della Corvara anti-pope, by whose influence, and the power of the Visconti, he designed to weaken the opposite faction in Tuscany and Lombardy. But Castruccio died, and his death caused the failure of the emperor's purpose; for Pisa and Lucca rebelled. The Pisans sent Piero della Corvara a prisoner to the pope in France, and the emperor, despairing of the affairs of Italy, returned to Germany. He had scarcely left, before John king of Bohemia came into the country, at the request of the Ghibellines of Brescia, and made himself lord of that city and of Bergamo. And as his entry was with the consent of the pope, although he feigned the contrary, the legate of Bologna favored him, thinking by this means to prevent the return of the emperor. This caused a change in the parties of Italy; for the Florentines and King Robert, finding the legate was favorable to the enterprises of the Ghibellines, became foes of all those to whom the legate and the king of Bohemia were friendly. Without having regard for either faction, whether Guelph or Ghibelline, many princes joined them, of whom, among others, were the Visconti, the Della Scala, Filippo Gonzao of Mantua, the Carrara, and those of Este. Upon this the pope excommunicated them all. The king, in fear of the league, went to collect forces in his own country, and having returned with a large army, still found his undertaking a difficult one; so, seeing his error, he withdrew to Bohemia, to the great displeasure of the legate, leaving only Reggio and Modena guarded, and Parma in the care of Marsilio and Piero de' Rossi, who were the most powerful men in the city. The king of Bohemia being gone, Bologna joined the league; and the leaguers divided among themselves the four cities which remained of the church faction. They agreed that Parma should pertain to the Della Scalla; Reggio to the Gonzaga; Modena to the family of Este, and Lucca to the Florentines. But in taking possession of these cities, many disputes arose which were afterward in a great measure settled by the Venetians. Some, perhaps, will think it a species of impropriety that we have so long deferred speaking of the Venetians, theirs being a republic, which, both on account of its power and internal regulations, deserves to be celebrated above any principality of Italy. But that this surprise may cease when the cause is known, I shall speak of their city from a more remote period; that everyone may understand what were their beginnings, and the causes which so long withheld them from interfering in the affairs of Italy.
When Attila, king of the Huns, besieged Aquileia, the inhabitants, after defending themselves a long time, began to despair of effecting their safety, and fled for refuge to several uninhabited rocks, situated at the point of the Adriatic Sea, now called the Gulf of Venice, carrying with them whatever movable property they possessed. The people of Padua, finding themselves in equal danger, and knowing that, having became master of Aquileia, Attila would next attack themselves, also removed with their most valuable property to a place on the same sea, called Rivo Alto, to which they brought their women, children, and aged persons, leaving the youth in Padua to assist in her defense. Besides these, the people of Monselice, with the inhabitants of the surrounding hills, driven by similar fears, fled to the same rocks. But after Attila had taken Aquileia, and destroyed Padua, Monselice, Vicenza, and Verona, the people of Padua and others who were powerful, continued to inhabit the marshes about Rivo Alto; and, in like manner, all the people of the province anciently called Venetia, driven by the same events, became collected in these marshes. Thus, under the pressure of necessity, they left an agreeable and fertile country to occupy one sterile and unwholesome. However, in consequence of a great number of people being drawn together into a comparatively small space, in a short time they made those places not only habitable, but delightful; and having established among themselves laws and useful regulations, enjoyed themselves in security amid the devastations of Italy, and soon increased both in reputation and strength. For, besides the inhabitants already mentioned, many fled to these places from the cities of Lombardy, principally to escape from the cruelties of Clefis king of the Lombards, which greatly tended to increase the numbers of the new city; and in the conventions which were made between Pepin, king of France, and the emperor of Greece, when the former, at the entreaty of the pope, came to drive the Lombards out of Italy, the duke of Benevento and the Venetians did not render obedience to either the one or the other, but alone enjoyed their liberty. As necessity had led them to dwell on sterile rocks, they were compelled to seek the means of subsistence elsewhere; and voyaging with their ships to every port of the ocean, their city became a depository for the various products of the world, and was itself filled with men of every nation.
For many years the Venetians sought no other dominion than that which tended to facilitate their commercial enterprises, and thus acquired many ports in Greece and Syria; and as the French had made frequent use of their ships in voyages to Asia, the island of Candia was assigned to them in recompense for these services. While they lived in this manner, their name spread terror over the seas, and was held in veneration throughout Italy. This was so completely the case, that they were generally chosen to arbitrate in controversies between the states, as occurred in the difference between the Colleagues, on account of the cities they had divided among themselves; which being referred to the Venetians, they awarded Brescia and Bergamo to the
