These towns found the advantage of drawing closer their alliance with the city which directed their party; of placing themselves under a more powerful protection; and of supporting their tribunals with a firmer hand. Martin della Torre had been elected podesta of Milan in 1256; three years later he obtained the title of elder, and lord of the people. At the same time, Lodi also named him lord. In 1263, the city of Novara conferred the same honour on him. Philip, who succeeded him in 1264, was named lord by Milan, Como, Vercelli, and Bergamo. Thus began to be formed among the Lombard republics, without their suspecting that they divested themselves of their liberty, the powerful state which a century and a half later became the duchy of Milan. But the pope, jealous of the house of della Torre, appointed archbishop of Milan Otto Visconti, whose family, powerful on the borders of Lake Maggiore, then shared the exile of the nobles and Ghibellines. This prelate placed himself at the head of their faction; and henceforward the rivalry between the families of Della Torre and Visconti made that between the people and the nobles almost forgotten. PERENNIAL STRIFE OF GUELFS AND GHIBELLINES [Sidenote: [1257-1261 A.D.]] The bitter enmity between the two parties of the Guelfs and Ghibellines was fatal to the cause of liberty. With the former, the question was religion--the independence of the church and of Italy, menaced by the Germans and Saracens, to whom Manfred granted not less confidence than Frederick II; with the latter, honour and good faith towards an illustrious family, and the support of the aristocracy as well as of royalty; but both were more intent on avenging offences a thousand times repeated, and guarding against exile, and the confiscation of property.
