AGE OF THE COMMUNES Rise of the Free Cities.—The final gainers, however, by the war of investitures, were the Italians. The antagonism of the popes to the emperors, which became hereditary in the Sacred College, forced the former to assume the protectorate of the national cause. And on the other hand, during the 47 years' war, the com munes grew in self-reliance, strength and liberty. The age of real autonomy, signalized by the supremacy of consuls in the cities, had arrived.
In the republics, government was carried on by officers called consuls, varying in number according to custom and according to the division of the town into districts. These magistrates were originally appointed to control and protect the humbler classes. But, in proportion as the people gained more power, the consuls rose into importance, superseded the bishops and began to repre sent the city in transactions with its neighbours. Popes and emperors who needed the assistance of a city had to seek it from the consuls, and thus these officers gradually converted an obscure and indefinite authority into what resembles the presidency of a commonwealth. They were supported by a deliberative assembly, called credenza, chosen from the more distinguished citizens. In addition to this privy council, we find a gran consiglio, consisting of the burghers, and a still larger assembly called parlamento, which included the whole adult population. Though the institu tions of the communes varied in different localities, this is the type to which they all approximated. The privileged burghers formed the aristocracy of the town, who by their wealth, usually derived from trade and industry, and birth, held its affairs within their custody.
Under their consuls the Italian cities rose to a great height of prosperity and splendour. It is also to be noticed that the people now began to be conscious of their past. They recognized the fact that their blood was Latin as distinguished from Teutonic, and the study of Roman law received a new impulse. The very name consul, no less than the Romanizing character of the best archi tecture of the time, points to the same revival of antiquity.
The rise of the Lombard communes produced a sympathetic revolution in Rome. A monk named Arnold of Brescia stirred up the Romans to shake off the temporal sway of their bishop. Rome, ever mindful of her unique past, listened to Arnold's preaching. A senate was established, and the republic was proclaimed. The title of patrician was revived and offered to Conrad, king of Italy, but not crowned emperor. Conrad refused it, and the Romans conferred it upon one of their own nobles. Though these institu tions borrowed high-sounding titles from antiquity, they were in reality imitations of the Lombard civic system. The pope was unable to check this revolution, which is now chiefly interesting as further proof of the insurgence of the Latin as against the feudal elements in Italy at this period (see ROME: History).
The division of the country between the pope's and emperor's parties inflicted upon Italy the ineradicable curse of party-warfare. Rome attempted to ruin Tivoli, and Genoa Pisa; Milan fought with Cremona, Cremona with Crema, Pavia with Verona, Verona with Padua, Piacenza with Parma, Modena and Reggio with Bologna, Bologna and Faenza with Ravenna and Imola, Florence and Pisa with Lucca and Siena, and so on through the whole list of cities. The nearer the neighbours, the more rancorous and in ternecine was the strife. Italy was, in fact, too small for her children. As the towns expanded, they perceived that they must mutually exclude each other. The pope's cause and the emperor's cause were of comparatively little moment to Italian burghers; and the names of Guelph and Ghibelline, which before long began to be heard in every street, on every market-place, had no mean ing for them. These watchwords are said to have arisen in Ger many during the disputed succession of the empire between 1135 and 1152, when the Welf s of Bavaria opposed the Swabian princes of Waiblingen origin. But in Italy, although they were severally identified with the papal and imperial parties, they really served as symbols for jealousies which altered in complexion from time to time and place to place.
