From the middle of the twelfth century we have seen nearly all the towns of northern Italy shake off the imperial yoke. Towards the end of the thirteenth the emperor Rudolf, instead of disputing their independence, offered to sell it to them for money. In the franchised communes there could no longer be any pretension to enslave fellow-citizens, but one could be made of governing them. Riches became a title for taking part in authority, by reason of the greater interest which the rich had in the preservation and order of society. It may be seen that a right derived from wealth is less extended than one derived from landed property. But in towns there could hardly be landed property properly so called. One could occupy a house, but not have those lands which, by their extent, position, and the number of men cultivating them, give power to their possessor. Moreover, the privileged classes in towns distinguished themselves from those in the country by the moderation of their pretensions. The latter were always seen on horseback, clothed in armour, helmets on their heads, and bearing arms whose use they reserved to themselves. They always recalled the fact that their right was founded on their force and valiance. In towns this apparel could have no use; riches would bring clients, and seduction gain friends. Little by little the exercise of authority, in so far as it was prolonged, happy, and met with favour, became a right to new marks of confidence, these being the supposed debt of those governed to those governing, and also supposed in the latter an increase of experience, a transmission of knowledge, of good rules, and a just ambition to make a name illustrious. [Sidenote: [1300-1350 A.D.]] The success of some lords had excited the ambition of all. But in the large towns the mass of the population opposed a strong resistance to them. Milan obliged its patricians to be content with a part of the magistrature. After having excited general indignation by taking every office, the Milanese nobles saw themselves reduced to signing a treaty with the plebeians by which the latter were admitted to an equal share in all public functions, from an ambassador’s charge to that of public trumpeter. The prouder ones retired to their castles and revenged themselves for their nullity by devastating the country. But even these devastations augmented the strength of the towns--that is, their population. The inhabitants, dispersed in a country open to ravages from the lords, ran to seek shelter for their families or goods in a walled city. Lordly feudal tyranny peopled the towns where so much resentment fermented against it and where increased industry and riches finally furnished the people the means of crushing these small tyrants.
